Let's divide 91025294 by 79
We want to divide 91025294 by 79.

Step 1:
If we divide 9 by 79, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 79

Advancing to step 2:
When dividing 91 by 79, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 79 from 91 leaves us with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 79

Going ahead to step 3:
120 divided by 79 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 79 from 120 to get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 79

Advancing to step 4:
If we divide 412 by 79, we get 5 and a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Subtracting 395 from 412 leaves us with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 79

Going ahead to step 5:
When dividing 175 by 79, we get 2 with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 1152.0
Deduct 158 from 175 and we're left with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 79

Moving on to step 6:
When dividing 172 by 79, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 11522.0
Deduct 158 from 172 and we're left with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 79

Going ahead to step 7:
79 goes into 149 1 times with a remainder of 70.
The next digit of our result is 1. 
Result so far: 115221.0
If we subtract 79 from 149, we get 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 79

Advancing to step 8:
704 divided by 79 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 1152218.0
If we subtract 632 from 704, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
79 can be fit into 720 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1152218.9
Subtracting 711 from 720 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
90 divided by 79 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1152218.91
If we take 79 away from 90, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
When dividing 110 by 79, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1152218.911
Subtracting 79 from 110 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 1152218.911 with a remainder of 0.0031.
