72662579 ÷ 198 
The aim is to understand the frequency of 198 in 72662579.

On to step 1:
7 divided by 198 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 198

Going ahead to step 2:
198 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 198

Let's proceed to step 3:
198 can be fit into 726 3 times, resulting in a remainder of 132.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 594 from 726 to get 132.
Take the next digit (6) from the dividend and append it to 132, then repeat: 1326 / 198

Moving on to step 4:
198 goes into 1326 6 times with a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 138 after subtracting 1188 from 1326.
Include the next digit (2) from the dividend after 138, then repeat: 1382 / 198

On to step 5:
198 can be fit into 1382 6 times, resulting in a remainder of 194.
Write down 6 as next digit of the result. 
Result so far: 366.0
The remainder is 194 after subtracting 1188 from 1382.
Append the next digit (5) from the dividend to 194 and continue with: 1945 / 198

Going ahead to step 6:
1945 divided by 198 is 9 with a remainder of 163.
The number 9 becomes the next digit in our result. 
Result so far: 3669.0
Subtracting 1782 from 1945 leaves us with 163.
Take the next digit (7) from the dividend and append it to 163, then repeat: 1637 / 198

Going ahead to step 7:
The number 198 fits into 1637 8 times, leaving a remainder of 53.
The next digit of our result is 8. 
Result so far: 36698.0
Subtracting 1584 from 1637 leaves us with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 198

Going ahead to step 8:
If we divide 539 by 198, we get 2 and a remainder of 143.
The next digit of our result is 2. 
Result so far: 366982.0
Subtract 396 from 539 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
198 goes into 1430 7 times with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 366982.7
The remainder is 44 after subtracting 1386 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
The number 198 fits into 440 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 366982.72
Subtract 396 from 440 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
The number 198 fits into 440 2 times, leaving a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 366982.722
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 366982.722 with a remaining 0.0044.
