Let's divide 86971252 by 163
We want to divide 86971252 by 163.

Step 1:
When dividing 8 by 163, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 163

Going ahead to step 2:
163 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 163

Moving on to step 3:
163 can be fit into 869 5 times, resulting in a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 54 after subtracting 815 from 869.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 163

Moving on to step 4:
163 can be fit into 547 3 times, resulting in a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 53.0
Deduct 489 from 547 and we're left with 58.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 163

Advancing to step 5:
The number 163 fits into 581 3 times, leaving a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 533.0
If we subtract 489 from 581, we get 92.
Grab the next digit (2) from the dividend, add it to 92, then carry on: 922 / 163

Going ahead to step 6:
When dividing 922 by 163, we get 5 with a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 5335.0
Subtract 815 from 922 to get 107.
Include the next digit (5) from the dividend after 107, then repeat: 1075 / 163

On to step 7:
If we divide 1075 by 163, we get 6 and a remainder of 97.
The next digit of our result is 6. 
Result so far: 53356.0
Subtract 978 from 1075 to get 97.
Append the next digit (2) from the dividend to 97 and continue with: 972 / 163

Moving on to step 8:
When dividing 972 by 163, we get 5 with a remainder of 157.
Put 5 as the next digit of the answer. 
Result so far: 533565.0
Subtracting 815 from 972 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
If we divide 1570 by 163, we get 9 and a remainder of 103.
Use 9 as the next digit of our solution. 
Result so far: 533565.9
The remainder is 103 after subtracting 1467 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 10:
When dividing 1030 by 163, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 533565.96
Deduct 978 from 1030 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
When dividing 520 by 163, we get 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 533565.963
Deduct 489 from 520 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
310 divided by 163 is 1 with a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 533565.9631
Subtract 163 from 310 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 13:
1470 divided by 163 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 533565.96319
Subtract 1467 from 1470 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
163 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 533565.96319
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
When dividing 300 by 163, we get 1 with a remainder of 137.
Record the quotient 1 as the next digit in the result. 
Result so far: 533565.9631901
The remainder is 137 after subtracting 163 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 16:
163 can be fit into 1370 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 533565.96319018
Subtracting 1304 from 1370 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 533565.96319018 and a remainder of 6.6e-08.
