125125 divided by 99 
We want to divide 125125 by 99.

Going ahead to step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 99

Advancing to step 2:
The number 99 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 99

Let's proceed to step 3:
125 divided by 99 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 99 from 125 and we're left with 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 99

Let's proceed to step 4:
261 divided by 99 is 2 with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 198 from 261 to get 63.
Include the next digit (2) from the dividend after 63, then repeat: 632 / 99

Moving on to step 5:
99 goes into 632 6 times with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we subtract 594 from 632, we get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 99

Moving on to step 6:
The number 99 fits into 385 3 times, leaving a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 1263.0
If we take 297 away from 385, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 7:
When dividing 880 by 99, we get 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 1263.8
If we subtract 792 from 880, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 8:
880 divided by 99 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 1263.88
If we take 792 away from 880, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 1263.88 and a remainder of 0.088.
