We divide 121658 by 99
Let's see how many times 99 fits into 121658.

Going ahead to step 1:
99 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up 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:
When dividing 12 by 99, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 99

On to step 3:
99 can be fit into 121 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 99 from 121, we get 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 99

Advancing to step 4:
When dividing 226 by 99, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 28 after subtracting 198 from 226.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 99

Step 5:
If we divide 285 by 99, we get 2 and a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 198 from 285 leaves us with 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 99

Moving on to step 6:
99 can be fit into 878 8 times, resulting in a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 1228.0
Subtracting 792 from 878 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 7:
860 divided by 99 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 1228.8
If we take 792 away from 860, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
99 can be fit into 680 6 times, resulting in a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 1228.86
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
99 goes into 860 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 1228.868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
99 goes into 680 6 times with a remainder of 86.
The next digit of our result is 6. 
Result so far: 1228.8686
Deduct 594 from 680 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 11:
The number 99 fits into 860 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 1228.86868
Subtract 792 from 860 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
The number 99 fits into 680 6 times, leaving a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 1228.868686
Deduct 594 from 680 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
When dividing 860 by 99, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 1228.8686868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 14:
99 can be fit into 680 6 times, resulting in a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 1228.86868686
If we take 594 away from 680, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 1228.86868686, with a leftover of 8.6e-08.
