Let's divide 79151521 by 313
We want to figure out the number of times 79151521 can be divided by 313.

Moving on to step 1:
If we divide 7 by 313, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 313

Let's proceed to step 2:
79 divided by 313 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 313

Step 3:
The number 313 fits into 791 2 times, leaving a remainder of 165.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 626 from 791 leaves us with 165.
Grab the next digit (5) from the dividend, add it to 165, then carry on: 1655 / 313

Going ahead to step 4:
If we divide 1655 by 313, we get 5 and a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 90 after subtracting 1565 from 1655.
Fetch the next digit (1) from the dividend, attach it to 90 and continue: 901 / 313

Advancing to step 5:
313 goes into 901 2 times with a remainder of 275.
The next digit of our result is 2. 
Result so far: 252.0
Subtracting 626 from 901 leaves us with 275.
Grab the next digit (5) from the dividend, add it to 275, then carry on: 2755 / 313

Advancing to step 6:
The number 313 fits into 2755 8 times, leaving a remainder of 251.
Write down 8 as next digit of the result. 
Result so far: 2528.0
The remainder is 251 after subtracting 2504 from 2755.
Bring next digit (2) of the dividend behind the 251 and repeat the process: 2512 / 313

Going ahead to step 7:
The number 313 fits into 2512 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 25288.0
Deduct 2504 from 2512 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 313

Advancing to step 8:
When dividing 81 by 313, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 252880.0
If we take 0 away from 81, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
810 divided by 313 is 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 252880.2
If we take 626 away from 810, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 10:
When dividing 1840 by 313, we get 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 252880.25
Deduct 1565 from 1840 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
The number 313 fits into 2750 8 times, leaving a remainder of 246.
The next digit of our result is 8. 
Result so far: 252880.258
If we subtract 2504 from 2750, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 12:
2460 divided by 313 is 7 with a remainder of 269.
The next digit of our result is 7. 
Result so far: 252880.2587
Subtracting 2191 from 2460 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 13:
2690 divided by 313 is 8 with a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 252880.25878
If we subtract 2504 from 2690, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 14:
The number 313 fits into 1860 5 times, leaving a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 252880.258785
The remainder is 295 after subtracting 1565 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 15:
313 can be fit into 2950 9 times, resulting in a remainder of 133.
The next digit of our result is 9. 
Result so far: 252880.2587859
The remainder is 133 after subtracting 2817 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Moving on to step 16:
If we divide 1330 by 313, we get 4 and a remainder of 78.
The next digit of our result is 4. 
Result so far: 252880.25878594
Deduct 1252 from 1330 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 252880.25878594 with a remainder of 7.8e-08.
