You are watching: What is 21 divided by 3 Here us will present you step-by-step with in-depth explanation how to calculation 21 separated by 3 using long division.Before friend continue, note that in the trouble 21 split by 3, the number are identified as follows:21 = dividend3 = divisorStep 1:Start by setting it up with the divisor 3 top top the left next andthe dividend 21 top top the right side prefer this:
 3 ⟌ 2 1
Step 2:
The divisor (3) goes into the very first digit the the dividend (2), 0 time(s). Therefore, put 0 on top:
 0 3 ⟌ 2 1
Step 3:
Multiply the divisor by the an outcome in the previous step (3 x 0 = 0) and write the answer below the dividend.
 0 3 ⟌ 2 1 0
Step 4:
Subtract the an outcome in the previous step from the first digit the the dividend (2 - 0 = 2) and also write the prize below.
 0 3 ⟌ 2 1 - 0 2
Step 5:
Move under the 2nd digit of the dividend (1) prefer this:
 0 3 ⟌ 2 1 - 0 2 1
Step 6:
The divisor (3) goes right into the bottom number (21), 7 time(s).

Therefore, put 7 top top top:
 0 7 3 ⟌ 2 1 - 0 2 1
Step 7:
Multiply the divisor by the result in the previous step (3 x 7 = 21) and also write that answer in ~ the bottom:
 0 7 3 ⟌ 2 1 - 0 2 1 2 1
Step 8:
Subtract the result in the previous step from the number written over it. (21 - 21 = 0) andwrite the answer at the bottom.
 0 7 3 ⟌ 2 1 - 0 2 1 - 2 1 0
You space done, since there space no an ext digits to move down from the dividend.The prize is the peak number and also the remainder is the bottom number.Therefore, the answer come 21 separated by 3 calculated using Long department is:7
