638873 ÷ 72 
We're looking to find how many times 72 goes into 638873.

Moving on to step 1:
72 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 72

Moving on to step 2:
72 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 72

Moving on to step 3:
When dividing 638 by 72, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 576 from 638 and we're left with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 72

Moving on to step 4:
72 can be fit into 628 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 88.0
If we take 576 away from 628, we end up with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 72

On to step 5:
72 can be fit into 527 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 887.0
The remainder is 23 after subtracting 504 from 527.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 72

Going ahead to step 6:
72 goes into 233 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 8873.0
Subtract 216 from 233 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
72 goes into 170 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 8873.2
Subtract 144 from 170 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
The number 72 fits into 260 3 times, leaving a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 8873.23
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
440 divided by 72 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8873.236
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
72 goes into 80 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 8873.2361
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 72, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 8873.23611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 8873.23611 with a remaining 8e-06.
