We look at the division of 15375689 by 198 
We want to figure out the number of times 15375689 can be divided by 198.

Step 1:
When dividing 1 by 198, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 198

Let's proceed to step 2:
When dividing 15 by 198, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 198

Advancing to step 3:
198 goes into 153 0 times with a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 153 to get 153.
Grab the next digit (7) from the dividend, add it to 153, then carry on: 1537 / 198

On to step 4:
1537 divided by 198 is 7 with a remainder of 151.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 1386 from 1537 to get 151.
Include the next digit (5) from the dividend after 151, then repeat: 1515 / 198

Let's proceed to step 5:
198 goes into 1515 7 times with a remainder of 129.
The next digit of our result is 7. 
Result so far: 77.0
If we subtract 1386 from 1515, we get 129.
Append the next digit (6) from the dividend to 129 and continue with: 1296 / 198

Step 6:
When dividing 1296 by 198, we get 6 with a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 776.0
If we subtract 1188 from 1296, we get 108.
Include the next digit (8) from the dividend after 108, then repeat: 1088 / 198

Advancing to step 7:
198 goes into 1088 5 times with a remainder of 98.
Record the quotient 5 as the next digit in the result. 
Result so far: 7765.0
Subtract 990 from 1088 to get 98.
Append the next digit (9) from the dividend to 98 and continue with: 989 / 198

On to step 8:
The number 198 fits into 989 4 times, leaving a remainder of 197.
Write down 4 as next digit of the result. 
Result so far: 77654.0
If we take 792 away from 989, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 9:
The number 198 fits into 1970 9 times, leaving a remainder of 188.
The number 9 becomes the next digit in our result. 
Result so far: 77654.9
If we take 1782 away from 1970, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 10:
When dividing 1880 by 198, we get 9 with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 77654.99
Subtract 1782 from 1880 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The quotient of the division is 77654.99, and the remainder is 0.098.
