Let's divide 102897 by 86
Our goal is to divide 102897 by 86.

Moving on to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 86

Advancing to step 2:
10 divided by 86 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 86

Going ahead to step 3:
When dividing 102 by 86, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 86 from 102 to get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 86

Step 4:
If we divide 168 by 86, we get 1 and a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 82 after subtracting 86 from 168.
Append the next digit (9) from the dividend to 82 and continue with: 829 / 86

On to step 5:
829 divided by 86 is 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 119.0
The remainder is 55 after subtracting 774 from 829.
Fetch the next digit (7) from the dividend, attach it to 55 and continue: 557 / 86

Advancing to step 6:
If we divide 557 by 86, we get 6 and a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 1196.0
Deduct 516 from 557 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
86 goes into 410 4 times with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 1196.4
Subtract 344 from 410 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1196.47
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
580 divided by 86 is 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1196.476
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 10:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1196.4767
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
If we divide 380 by 86, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 1196.47674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
If we divide 360 by 86, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1196.476744
If we subtract 344 from 360, 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.

After the division, we end up with 1196.476744 and a remainder of 1.6e-06.
