79786561 divided by 315 
We want to divide 79786561 by 315.

Going ahead to step 1:
7 divided by 315 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 315

Moving on to step 2:
315 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 315

Let's proceed to step 3:
315 goes into 797 2 times with a remainder of 167.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 630 from 797 leaves us with 167.
Fetch the next digit (8) from the dividend, attach it to 167 and continue: 1678 / 315

On to step 4:
1678 divided by 315 is 5 with a remainder of 103.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 1575 from 1678 to get 103.
Take the next digit (6) from the dividend and append it to 103, then repeat: 1036 / 315

Moving on to step 5:
315 goes into 1036 3 times with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 253.0
If we subtract 945 from 1036, we get 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 315

On to step 6:
315 goes into 915 2 times with a remainder of 285.
Write down 2 as next digit of the result. 
Result so far: 2532.0
If we take 630 away from 915, we end up with 285.
Fetch the next digit (6) from the dividend, attach it to 285 and continue: 2856 / 315

Moving on to step 7:
315 can be fit into 2856 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 25329.0
Deduct 2835 from 2856 and we're left with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 315

Going ahead to step 8:
When dividing 211 by 315, we get 0 with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 253290.0
The remainder is 211 after subtracting 0 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
315 goes into 2110 6 times with a remainder of 220.
The next digit of our result is 6. 
Result so far: 253290.6
If we subtract 1890 from 2110, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
315 can be fit into 2200 6 times, resulting in a remainder of 310.
Write down 6 as next digit of the result. 
Result so far: 253290.66
Subtracting 1890 from 2200 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 253290.66 and a remainder of 0.31.
