We look at the division of 80931782 by 315 
We want to figure out the number of times 80931782 can be divided by 315.

On to step 1:
If we divide 8 by 315, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 315

Going ahead to step 2:
When dividing 80 by 315, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 315

Moving on to step 3:
315 can be fit into 809 2 times, resulting in a remainder of 179.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 179 after subtracting 630 from 809.
Fetch the next digit (3) from the dividend, attach it to 179 and continue: 1793 / 315

Step 4:
315 goes into 1793 5 times with a remainder of 218.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1575 from 1793 to get 218.
Fetch the next digit (1) from the dividend, attach it to 218 and continue: 2181 / 315

Step 5:
The number 315 fits into 2181 6 times, leaving a remainder of 291.
Write down 6 as next digit of the result. 
Result so far: 256.0
The remainder is 291 after subtracting 1890 from 2181.
Fetch the next digit (7) from the dividend, attach it to 291 and continue: 2917 / 315

Going ahead to step 6:
2917 divided by 315 is 9 with a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 2569.0
Subtracting 2835 from 2917 leaves us with 82.
Append the next digit (8) from the dividend to 82 and continue with: 828 / 315

Going ahead to step 7:
When dividing 828 by 315, we get 2 with a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 25692.0
The remainder is 198 after subtracting 630 from 828.
Append the next digit (2) from the dividend to 198 and continue with: 1982 / 315

Moving on to step 8:
If we divide 1982 by 315, we get 6 and a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 256926.0
The remainder is 92 after subtracting 1890 from 1982.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 9:
The number 315 fits into 920 2 times, leaving a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 256926.2
Subtracting 630 from 920 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
315 goes into 2900 9 times with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 256926.29
Deduct 2835 from 2900 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
315 goes into 650 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 256926.292
Deduct 630 from 650 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
315 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 256926.292
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
If we divide 2000 by 315, we get 6 and a remainder of 110.
Put 6 as the next digit of the answer. 
Result so far: 256926.29206
If we subtract 1890 from 2000, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 14:
315 goes into 1100 3 times with a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 256926.292063
Subtract 945 from 1100 to 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.

Let's proceed to step 15:
When dividing 1550 by 315, we get 4 with a remainder of 290.
The number 4 becomes the next digit in our result. 
Result so far: 256926.2920634
Deduct 1260 from 1550 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 16:
315 can be fit into 2900 9 times, resulting in a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 256926.29206349
Deduct 2835 from 2900 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 256926.29206349, and the remainder is 6.5e-08.
