91149987 ÷ 790 
We want to figure out the number of times 91149987 can be divided by 790.

Going ahead to step 1:
The number 790 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 790

Step 2:
The number 790 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 790

Going ahead to step 3:
The number 790 fits into 911 1 times, leaving a remainder of 121.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 790 from 911, we get 121.
Fetch the next digit (4) from the dividend, attach it to 121 and continue: 1214 / 790

Going ahead to step 4:
The number 790 fits into 1214 1 times, leaving a remainder of 424.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 790 from 1214 leaves us with 424.
Fetch the next digit (9) from the dividend, attach it to 424 and continue: 4249 / 790

Let's proceed to step 5:
4249 divided by 790 is 5 with a remainder of 299.
Write down 5 as next digit of the result. 
Result so far: 115.0
If we take 3950 away from 4249, we end up with 299.
Append the next digit (9) from the dividend to 299 and continue with: 2999 / 790

On to step 6:
2999 divided by 790 is 3 with a remainder of 629.
The number 3 becomes the next digit in our result. 
Result so far: 1153.0
If we subtract 2370 from 2999, we get 629.
Include the next digit (8) from the dividend after 629, then repeat: 6298 / 790

Moving on to step 7:
If we divide 6298 by 790, we get 7 and a remainder of 768.
The next digit of our result is 7. 
Result so far: 11537.0
If we take 5530 away from 6298, we end up with 768.
Fetch the next digit (7) from the dividend, attach it to 768 and continue: 7687 / 790

On to step 8:
The number 790 fits into 7687 9 times, leaving a remainder of 577.
The number 9 becomes the next digit in our result. 
Result so far: 115379.0
The remainder is 577 after subtracting 7110 from 7687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 9:
5770 divided by 790 is 7 with a remainder of 240.
The next digit of our result is 7. 
Result so far: 115379.7
If we subtract 5530 from 5770, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
The number 790 fits into 2400 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 115379.73
Subtract 2370 from 2400 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 790 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 115379.73
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
The number 790 fits into 3000 3 times, leaving a remainder of 630.
Use 3 as the next digit of our solution. 
Result so far: 115379.7303
Subtract 2370 from 3000 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 13:
790 can be fit into 6300 7 times, resulting in a remainder of 770.
Put 7 as the next digit of the answer. 
Result so far: 115379.73037
If we take 5530 away from 6300, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 14:
790 can be fit into 7700 9 times, resulting in a remainder of 590.
The next digit of our result is 9. 
Result so far: 115379.730379
Subtract 7110 from 7700 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 15:
When dividing 5900 by 790, we get 7 with a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 115379.7303797
Deduct 5530 from 5900 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 16:
790 can be fit into 3700 4 times, resulting in a remainder of 540.
Write down 4 as next digit of the result. 
Result so far: 115379.73037974
The remainder is 540 after subtracting 3160 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

In conclusion, the division gives 115379.73037974 with a balance of 5.4e-07.
