We're dividing 124242 by 99 
We want to figure out the number of times 124242 can be divided by 99.

Step 1:
If we divide 1 by 99, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 99

Advancing to step 2:
99 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 99

Moving on to step 3:
If we divide 124 by 99, we get 1 and a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 99 from 124 and we're left with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 99

Advancing to step 4:
If we divide 252 by 99, we get 2 and a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 198 from 252, we get 54.
Take the next digit (4) from the dividend and append it to 54, then repeat: 544 / 99

Moving on to step 5:
When dividing 544 by 99, we get 5 with a remainder of 49.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 495 from 544 leaves us with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 99

On to step 6:
If we divide 492 by 99, we get 4 and a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 1254.0
The remainder is 96 after subtracting 396 from 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 7:
99 goes into 960 9 times with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 1254.9
The remainder is 69 after subtracting 891 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
When dividing 690 by 99, we get 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 1254.96
If we take 594 away from 690, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 9:
960 divided by 99 is 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 1254.969
Deduct 891 from 960 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
When dividing 690 by 99, we get 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 1254.9696
Deduct 594 from 690 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
The number 99 fits into 960 9 times, leaving a remainder of 69.
The next digit of our result is 9. 
Result so far: 1254.96969
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
When dividing 690 by 99, we get 6 with a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 1254.969696
If we take 594 away from 690, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
The number 99 fits into 960 9 times, leaving a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 1254.9696969
Deduct 891 from 960 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 14:
690 divided by 99 is 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 1254.96969696
Subtracting 594 from 690 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 1254.96969696, with a leftover of 9.6e-08.
