We divide 124145 by 99
We're looking to find how many times 99 goes into 124145.

Going ahead to step 1:
The number 99 fits into 1 0 times, leaving 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 99

Let's proceed to step 2:
If we divide 12 by 99, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 99

On to step 3:
When dividing 124 by 99, we get 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 99 from 124 leaves us with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 99

Going ahead to step 4:
99 can be fit into 251 2 times, resulting in a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 198 from 251 leaves us with 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 99

Going ahead to step 5:
The number 99 fits into 534 5 times, leaving a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 495 from 534, we get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 99

Going ahead to step 6:
395 divided by 99 is 3 with a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 1253.0
Subtracting 297 from 395 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 7:
If we divide 980 by 99, we get 9 and a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 1253.9
Deduct 891 from 980 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 8:
When dividing 890 by 99, we get 8 with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 1253.98
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 9:
When dividing 980 by 99, we get 9 with a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 1253.989
If we subtract 891 from 980, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 10:
99 can be fit into 890 8 times, resulting in a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 1253.9898
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
99 goes into 980 9 times with a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 1253.98989
The remainder is 89 after subtracting 891 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 12:
890 divided by 99 is 8 with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 1253.989898
Subtract 792 from 890 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 13:
The number 99 fits into 980 9 times, leaving a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 1253.9898989
If we take 891 away from 980, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 14:
99 can be fit into 890 8 times, resulting in a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 1253.98989898
If we take 792 away from 890, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 1253.98989898, with a leftover of 9.8e-08.
