We're dividing 198151 by 25 
Let's see how many times 25 fits into 198151.

Advancing to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 25

Going ahead to step 2:
19 divided by 25 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 25

Let's proceed to step 3:
When dividing 198 by 25, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 175 from 198 to get 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 25

Step 4:
231 divided by 25 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we subtract 225 from 231, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 25

Going ahead to step 5:
The number 25 fits into 65 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 792.0
If we subtract 50 from 65, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 25

Step 6:
25 goes into 151 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 7926.0
Subtract 150 from 151 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 25, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7926.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 7926.04
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7926.04
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7926.04
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 7926.04 and a remainder of 0.0.
