We divide 90116839 by 198
The aim is to understand the frequency of 198 in 90116839.

Let's proceed to step 1:
The number 198 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 198

Advancing to step 2:
90 divided by 198 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 198

On to step 3:
198 goes into 901 4 times with a remainder of 109.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 792 from 901 leaves us with 109.
Take the next digit (1) from the dividend and append it to 109, then repeat: 1091 / 198

Advancing to step 4:
When dividing 1091 by 198, we get 5 with a remainder of 101.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 990 from 1091 to get 101.
Bring next digit (6) of the dividend behind the 101 and repeat the process: 1016 / 198

Going ahead to step 5:
198 goes into 1016 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 455.0
The remainder is 26 after subtracting 990 from 1016.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 198

Moving on to step 6:
198 goes into 268 1 times with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 4551.0
Subtracting 198 from 268 leaves us with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 198

Moving on to step 7:
The number 198 fits into 703 3 times, leaving a remainder of 109.
Put 3 as the next digit of the answer. 
Result so far: 45513.0
If we take 594 away from 703, we end up with 109.
Fetch the next digit (9) from the dividend, attach it to 109 and continue: 1099 / 198

Going ahead to step 8:
The number 198 fits into 1099 5 times, leaving a remainder of 109.
The next digit of our result is 5. 
Result so far: 455135.0
Subtracting 990 from 1099 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 9:
When dividing 1090 by 198, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 455135.5
Deduct 990 from 1090 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
198 goes into 1000 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 455135.55
Deduct 990 from 1000 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 455135.55 and a remainder of 0.01.
