79407555 ÷ 313 
We want to divide 79407555 by 313.

Step 1:
When dividing 7 by 313, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 313

Going ahead to step 2:
313 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 313

Going ahead to step 3:
313 can be fit into 794 2 times, resulting in a remainder of 168.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 626 from 794 to get 168.
Bring next digit (0) of the dividend behind the 168 and repeat the process: 1680 / 313

On to step 4:
The number 313 fits into 1680 5 times, leaving a remainder of 115.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 1565 from 1680 to get 115.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 313

On to step 5:
313 can be fit into 1157 3 times, resulting in a remainder of 218.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
Subtracting 939 from 1157 leaves us with 218.
Append the next digit (5) from the dividend to 218 and continue with: 2185 / 313

On to step 6:
If we divide 2185 by 313, we get 6 and a remainder of 307.
The next digit of our result is 6. 
Result so far: 2536.0
Subtract 1878 from 2185 to get 307.
Bring next digit (5) of the dividend behind the 307 and repeat the process: 3075 / 313

Moving on to step 7:
The number 313 fits into 3075 9 times, leaving a remainder of 258.
Write down 9 as next digit of the result. 
Result so far: 25369.0
Subtracting 2817 from 3075 leaves us with 258.
Take the next digit (5) from the dividend and append it to 258, then repeat: 2585 / 313

Let's proceed to step 8:
313 goes into 2585 8 times with a remainder of 81.
Record the quotient 8 as the next digit in the result. 
Result so far: 253698.0
Subtracting 2504 from 2585 leaves us 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.

Let's proceed to step 9:
313 goes into 810 2 times with a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 253698.2
If we subtract 626 from 810, we get 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.
Use 5 as the next digit of our solution. 
Result so far: 253698.25
The remainder is 275 after subtracting 1565 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 11:
When dividing 2750 by 313, we get 8 with a remainder of 246.
The number 8 becomes the next digit in our result. 
Result so far: 253698.258
If we take 2504 away from 2750, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 12:
313 can be fit into 2460 7 times, resulting in a remainder of 269.
Write down 7 as next digit of the result. 
Result so far: 253698.2587
Subtract 2191 from 2460 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 13:
The number 313 fits into 2690 8 times, leaving a remainder of 186.
Put 8 as the next digit of the answer. 
Result so far: 253698.25878
The remainder is 186 after subtracting 2504 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
If we divide 1860 by 313, we get 5 and a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 253698.258785
Subtracting 1565 from 1860 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Step 15:
2950 divided by 313 is 9 with a remainder of 133.
The number 9 becomes the next digit in our result. 
Result so far: 253698.2587859
If we take 2817 away from 2950, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 16:
If we divide 1330 by 313, we get 4 and a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 253698.25878594
If we subtract 1252 from 1330, we get 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 253698.25878594 with a remainder of 7.8e-08.
