Let's divide 86870640 by 913
Our goal is to divide 86870640 by 913.

Going ahead to step 1:
913 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 913

On to step 2:
913 goes into 86 0 times with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 913

Step 3:
The number 913 fits into 868 0 times, leaving a remainder of 868.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 868 to get 868.
Fetch the next digit (7) from the dividend, attach it to 868 and continue: 8687 / 913

Let's proceed to step 4:
The number 913 fits into 8687 9 times, leaving a remainder of 470.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 8217 from 8687 and we're left with 470.
Include the next digit (0) from the dividend after 470, then repeat: 4700 / 913

Going ahead to step 5:
The number 913 fits into 4700 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtract 4565 from 4700 to get 135.
Include the next digit (6) from the dividend after 135, then repeat: 1356 / 913

Moving on to step 6:
913 goes into 1356 1 times with a remainder of 443.
The number 1 becomes the next digit in our result. 
Result so far: 951.0
Subtracting 913 from 1356 leaves us with 443.
Take the next digit (4) from the dividend and append it to 443, then repeat: 4434 / 913

Advancing to step 7:
913 goes into 4434 4 times with a remainder of 782.
Record the quotient 4 as the next digit in the result. 
Result so far: 9514.0
If we subtract 3652 from 4434, we get 782.
Include the next digit (0) from the dividend after 782, then repeat: 7820 / 913

Step 8:
The number 913 fits into 7820 8 times, leaving a remainder of 516.
Write down 8 as next digit of the result. 
Result so far: 95148.0
Deduct 7304 from 7820 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
913 goes into 5160 5 times with a remainder of 595.
Record the quotient 5 as the next digit in the result. 
Result so far: 95148.5
Deduct 4565 from 5160 and we're left with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Step 10:
When dividing 5950 by 913, we get 6 with a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 95148.56
The remainder is 472 after subtracting 5478 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 11:
If we divide 4720 by 913, we get 5 and a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 95148.565
If we subtract 4565 from 4720, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 12:
913 can be fit into 1550 1 times, resulting in a remainder of 637.
The next digit of our result is 1. 
Result so far: 95148.5651
If we subtract 913 from 1550, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Let's proceed to step 13:
When dividing 6370 by 913, we get 6 with a remainder of 892.
The next digit of our result is 6. 
Result so far: 95148.56516
Subtract 5478 from 6370 to get 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Moving on to step 14:
913 goes into 8920 9 times with a remainder of 703.
Put 9 as the next digit of the answer. 
Result so far: 95148.565169
The remainder is 703 after subtracting 8217 from 8920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Step 15:
913 can be fit into 7030 7 times, resulting in a remainder of 639.
The number 7 becomes the next digit in our result. 
Result so far: 95148.5651697
If we take 6391 away from 7030, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Advancing to step 16:
6390 divided by 913 is 6 with a remainder of 912.
Record the quotient 6 as the next digit in the result. 
Result so far: 95148.56516976
The remainder is 912 after subtracting 5478 from 6390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9120, and continue the process.

After the division, we end up with 95148.56516976 and a remainder of 9.12e-07.
