We divide 86857 by 72
We want to divide 86857 by 72.

Advancing to step 1:
The number 72 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 72

Going ahead to step 2:
The number 72 fits into 86 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 72 from 86 to get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 72

Step 3:
148 divided by 72 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 144 from 148 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 72

On to step 4:
The number 72 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtract 0 from 45 to get 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 72

Going ahead to step 5:
72 can be fit into 457 6 times, resulting in a remainder of 25.
The next digit of our result is 6. 
Result so far: 1206.0
Subtracting 432 from 457 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 6:
250 divided by 72 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 1206.3
Deduct 216 from 250 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
The number 72 fits into 340 4 times, leaving a remainder of 52.
The next digit of our result is 4. 
Result so far: 1206.34
Subtract 288 from 340 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
72 goes into 520 7 times with a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1206.347
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1206.3472
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
72 goes into 160 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 1206.34722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1206.34722 and a remainder of 1.6e-05.
