We look at the division of 25570603 by 198 
We want to divide 25570603 by 198.

Advancing to step 1:
198 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 198

On to step 2:
25 divided by 198 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 198

Going ahead to step 3:
198 can be fit into 255 1 times, resulting in a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 198 from 255 to get 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 198

Moving on to step 4:
The number 198 fits into 577 2 times, leaving a remainder of 181.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 396 away from 577, we end up with 181.
Bring next digit (0) of the dividend behind the 181 and repeat the process: 1810 / 198

Let's proceed to step 5:
198 goes into 1810 9 times with a remainder of 28.
The next digit of our result is 9. 
Result so far: 129.0
If we take 1782 away from 1810, we end up with 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 198

Step 6:
198 goes into 286 1 times with a remainder of 88.
The next digit of our result is 1. 
Result so far: 1291.0
If we take 198 away from 286, we end up with 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 198

Advancing to step 7:
880 divided by 198 is 4 with a remainder of 88.
The next digit of our result is 4. 
Result so far: 12914.0
Subtracting 792 from 880 leaves us with 88.
Grab the next digit (3) from the dividend, add it to 88, then carry on: 883 / 198

Let's proceed to step 8:
198 can be fit into 883 4 times, resulting in a remainder of 91.
Write down 4 as next digit of the result. 
Result so far: 129144.0
If we take 792 away from 883, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 9:
198 goes into 910 4 times with a remainder of 118.
Record the quotient 4 as the next digit in the result. 
Result so far: 129144.4
If we subtract 792 from 910, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
198 can be fit into 1180 5 times, resulting in a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 129144.45
If we subtract 990 from 1180, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 11:
198 can be fit into 1900 9 times, resulting in a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 129144.459
Deduct 1782 from 1900 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 12:
When dividing 1180 by 198, we get 5 with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 129144.4595
The remainder is 190 after subtracting 990 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 13:
1900 divided by 198 is 9 with a remainder of 118.
Use 9 as the next digit of our solution. 
Result so far: 129144.45959
If we take 1782 away from 1900, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 14:
198 goes into 1180 5 times with a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 129144.459595
Subtracting 990 from 1180 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
198 goes into 1900 9 times with a remainder of 118.
Write down 9 as next digit of the result. 
Result so far: 129144.4595959
Subtracting 1782 from 1900 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 16:
198 can be fit into 1180 5 times, resulting in a remainder of 190.
The next digit of our result is 5. 
Result so far: 129144.45959595
If we subtract 990 from 1180, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final result is 129144.45959595 with a remainder of 1.9e-07.
