We look at the division of 79531311 by 948 
We want to divide 79531311 by 948.

On to step 1:
The number 948 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 948

On to step 2:
When dividing 79 by 948, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Fetch the next digit (5) from the dividend, attach it to 79 and continue: 795 / 948

Let's proceed to step 3:
948 goes into 795 0 times with a remainder of 795.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 795 after subtracting 0 from 795.
Include the next digit (3) from the dividend after 795, then repeat: 7953 / 948

Moving on to step 4:
948 can be fit into 7953 8 times, resulting in a remainder of 369.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 7584 from 7953 to get 369.
Fetch the next digit (1) from the dividend, attach it to 369 and continue: 3691 / 948

Going ahead to step 5:
The number 948 fits into 3691 3 times, leaving a remainder of 847.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 847 after subtracting 2844 from 3691.
Include the next digit (3) from the dividend after 847, then repeat: 8473 / 948

On to step 6:
948 can be fit into 8473 8 times, resulting in a remainder of 889.
Use 8 as the next digit of our solution. 
Result so far: 838.0
If we take 7584 away from 8473, we end up with 889.
Bring next digit (1) of the dividend behind the 889 and repeat the process: 8891 / 948

Step 7:
8891 divided by 948 is 9 with a remainder of 359.
Write down 9 as next digit of the result. 
Result so far: 8389.0
Deduct 8532 from 8891 and we're left with 359.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 948

Step 8:
3591 divided by 948 is 3 with a remainder of 747.
Put 3 as the next digit of the answer. 
Result so far: 83893.0
The remainder is 747 after subtracting 2844 from 3591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Going ahead to step 9:
If we divide 7470 by 948, we get 7 and a remainder of 834.
Record the quotient 7 as the next digit in the result. 
Result so far: 83893.7
Subtract 6636 from 7470 to get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Moving on to step 10:
When dividing 8340 by 948, we get 8 with a remainder of 756.
The number 8 becomes the next digit in our result. 
Result so far: 83893.78
Subtract 7584 from 8340 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Step 11:
948 goes into 7560 7 times with a remainder of 924.
The next digit of our result is 7. 
Result so far: 83893.787
Subtract 6636 from 7560 to get 924.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9240, and continue the process.

On to step 12:
9240 divided by 948 is 9 with a remainder of 708.
The next digit of our result is 9. 
Result so far: 83893.7879
Subtract 8532 from 9240 to get 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Going ahead to step 13:
7080 divided by 948 is 7 with a remainder of 444.
The number 7 becomes the next digit in our result. 
Result so far: 83893.78797
If we subtract 6636 from 7080, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 14:
When dividing 4440 by 948, we get 4 with a remainder of 648.
Record the quotient 4 as the next digit in the result. 
Result so far: 83893.787974
The remainder is 648 after subtracting 3792 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 15:
948 can be fit into 6480 6 times, resulting in a remainder of 792.
Record the quotient 6 as the next digit in the result. 
Result so far: 83893.7879746
If we take 5688 away from 6480, we end up with 792.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Going ahead to step 16:
The number 948 fits into 7920 8 times, leaving a remainder of 336.
The next digit of our result is 8. 
Result so far: 83893.78797468
Subtracting 7584 from 7920 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final result is 83893.78797468 with a remainder of 3.36e-07.
