We look at the division of 15877697 by 198 
We want to divide 15877697 by 198.

On to step 1:
When dividing 1 by 198, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 198

On to step 2:
15 divided by 198 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 198

Let's proceed to step 3:
158 divided by 198 is 0 with a remainder of 158.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Append the next digit (7) from the dividend to 158 and continue with: 1587 / 198

Going ahead to step 4:
The number 198 fits into 1587 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 1584 from 1587, we get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 198

On to step 5:
The number 198 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 37 to get 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 198

Moving on to step 6:
When dividing 376 by 198, we get 1 with a remainder of 178.
The next digit of our result is 1. 
Result so far: 801.0
If we subtract 198 from 376, we get 178.
Fetch the next digit (9) from the dividend, attach it to 178 and continue: 1789 / 198

On to step 7:
When dividing 1789 by 198, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 8019.0
If we take 1782 away from 1789, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 198

Let's proceed to step 8:
198 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 80190.0
If we subtract 0 from 77, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 9:
If we divide 770 by 198, we get 3 and a remainder of 176.
Record the quotient 3 as the next digit in the result. 
Result so far: 80190.3
Subtract 594 from 770 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
198 goes into 1760 8 times with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 80190.38
Subtract 1584 from 1760 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
198 can be fit into 1760 8 times, resulting in a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 80190.388
Subtracting 1584 from 1760 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Our division results in 80190.388 with a remaining 0.0176.
