The number 198 fits into 1199 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 25426.0
The remainder is 11 after subtracting 1188 from 1199.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 198

Going ahead to step 8:
198 can be fit into 112 0 times, resulting in a remainder of 112.
Put 0 as the next digit of the answer. 
Result so far: 254260.0
The remainder is 112 after subtracting 0 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
If we divide 1300 by 198, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 254260.56
Subtract 1188 from 1300 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
When dividing 1120 by 198, we get 5 with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 254260.565
If we subtract 990 from 1120, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 12:
If we divide 1300 by 198, we get 6 and a remainder of 112.
The next digit of our result is 6. 
Result so far: 254260.5656
Subtract 1188 from 1300 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
1120 divided by 198 is 5 with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 254260.56565
Subtracting 990 from 1120 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
If we divide 1300 by 198, we get 6 and a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 254260.565656
Subtract 1188 from 1300 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 15:
The number 198 fits into 1120 5 times, leaving a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 254260.5656565
The remainder is 130 after subtracting 990 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 16:
198 can be fit into 1300 6 times, resulting in a remainder of 112.
Put 6 as the next digit of the answer. 
Result so far: 254260.56565656
