The aim is to understand the frequency of 198 in 15712447.

Step 1:
1 divided by 198 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 198

Advancing to step 2:
When dividing 15 by 198, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 198

Going ahead to step 3:
198 goes into 157 0 times with a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 157, we get 157.
Append the next digit (1) from the dividend to 157 and continue with: 1571 / 198

Advancing to step 4:
When dividing 1571 by 198, we get 7 with a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 1386 away from 1571, we end up with 185.
Fetch the next digit (2) from the dividend, attach it to 185 and continue: 1852 / 198

Let's proceed to step 5:
When dividing 1852 by 198, we get 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 70 after subtracting 1782 from 1852.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 198

On to step 6:
The number 198 fits into 704 3 times, leaving a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 793.0
Subtracting 594 from 704 leaves us with 110.
Include the next digit (4) from the dividend after 110, then repeat: 1104 / 198

Let's proceed to step 7:
The number 198 fits into 1104 5 times, leaving a remainder of 114.
Put 5 as the next digit of the answer. 
Result so far: 7935.0
If we subtract 990 from 1104, we get 114.
Fetch the next digit (7) from the dividend, attach it to 114 and continue: 1147 / 198

Advancing to step 8:
1147 divided by 198 is 5 with a remainder of 157.
Record the quotient 5 as the next digit in the result. 
Result so far: 79355.0
Subtract 990 from 1147 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
The number 198 fits into 1570 7 times, leaving a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 79355.7
Subtract 1386 from 1570 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 10:
If we divide 1840 by 198, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 79355.79
Subtract 1782 from 1840 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
580 divided by 198 is 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 79355.792
The remainder is 184 after subtracting 396 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 12:
198 can be fit into 1840 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 79355.7929
If we take 1782 away from 1840, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
198 can be fit into 580 2 times, resulting in a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 79355.79292
Subtract 396 from 580 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 14:
The number 198 fits into 1840 9 times, leaving a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 79355.792929
Deduct 1782 from 1840 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 15:
The number 198 fits into 580 2 times, leaving a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 79355.7929292
Subtract 396 from 580 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 16:
1840 divided by 198 is 9 with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 79355.79292929
Subtracting 1782 from 1840 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.
