We're dividing 99790501 by 869 
We want to figure out the number of times 99790501 can be divided by 869.

On to step 1:
869 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 869

Moving on to step 2:
869 can be fit into 99 0 times, resulting in a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 869

Advancing to step 3:
869 can be fit into 997 1 times, resulting in a remainder of 128.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 869 from 997 to get 128.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 869

On to step 4:
869 can be fit into 1289 1 times, resulting in a remainder of 420.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 869 from 1289, we get 420.
Take the next digit (0) from the dividend and append it to 420, then repeat: 4200 / 869

Going ahead to step 5:
If we divide 4200 by 869, we get 4 and a remainder of 724.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Deduct 3476 from 4200 and we're left with 724.
Grab the next digit (5) from the dividend, add it to 724, then carry on: 7245 / 869

Advancing to step 6:
869 can be fit into 7245 8 times, resulting in a remainder of 293.
The number 8 becomes the next digit in our result. 
Result so far: 1148.0
If we take 6952 away from 7245, we end up with 293.
Grab the next digit (0) from the dividend, add it to 293, then carry on: 2930 / 869

On to step 7:
2930 divided by 869 is 3 with a remainder of 323.
The next digit of our result is 3. 
Result so far: 11483.0
If we subtract 2607 from 2930, we get 323.
Bring next digit (1) of the dividend behind the 323 and repeat the process: 3231 / 869

Advancing to step 8:
3231 divided by 869 is 3 with a remainder of 624.
The number 3 becomes the next digit in our result. 
Result so far: 114833.0
The remainder is 624 after subtracting 2607 from 3231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Going ahead to step 9:
If we divide 6240 by 869, we get 7 and a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 114833.7
If we take 6083 away from 6240, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 10:
869 can be fit into 1570 1 times, resulting in a remainder of 701.
The number 1 becomes the next digit in our result. 
Result so far: 114833.71
Subtracting 869 from 1570 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Going ahead to step 11:
If we divide 7010 by 869, we get 8 and a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 114833.718
Subtract 6952 from 7010 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
When dividing 580 by 869, we get 0 with a remainder of 580.
The next digit of our result is 0. 
Result so far: 114833.718
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 13:
869 goes into 5800 6 times with a remainder of 586.
Put 6 as the next digit of the answer. 
Result so far: 114833.71806
The remainder is 586 after subtracting 5214 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 14:
When dividing 5860 by 869, we get 6 with a remainder of 646.
Write down 6 as next digit of the result. 
Result so far: 114833.718066
Deduct 5214 from 5860 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

The final outcome is 114833.718066, with a leftover of 6.46e-05.
