121413 divided by 99 
We're looking to find how many times 99 goes into 121413.

Moving on to step 1:
If we divide 1 by 99, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 99

Moving on to step 2:
99 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 99

Let's proceed to step 3:
If we divide 121 by 99, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 99 from 121 to get 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 99

Step 4:
The number 99 fits into 224 2 times, leaving a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 198 from 224 to get 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 99

Advancing to step 5:
261 divided by 99 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we take 198 away from 261, we end up with 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 99

Going ahead to step 6:
99 can be fit into 633 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 1226.0
Deduct 594 from 633 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
390 divided by 99 is 3 with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 1226.3
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 8:
99 can be fit into 930 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 1226.39
If we take 891 away from 930, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
When dividing 390 by 99, we get 3 with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 1226.393
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 10:
99 goes into 930 9 times with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 1226.3939
If we take 891 away from 930, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 11:
When dividing 390 by 99, we get 3 with a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 1226.39393
Subtracting 297 from 390 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 12:
99 can be fit into 930 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 1226.393939
Subtracting 891 from 930 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
When dividing 390 by 99, we get 3 with a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 1226.3939393
Deduct 297 from 390 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 14:
99 can be fit into 930 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 1226.39393939
Subtracting 891 from 930 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 1226.39393939 with a remaining 3.9e-08.
