We divide 91798899 by 54
The aim is to understand the frequency of 54 in 91798899.

Advancing to step 1:
When dividing 9 by 54, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 54

Step 2:
When dividing 91 by 54, we get 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 54 from 91, we get 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 54

Step 3:
When dividing 377 by 54, we get 6 with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 324 from 377 leaves us with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 54

On to step 4:
54 goes into 539 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Subtract 486 from 539 to get 53.
Grab the next digit (8) from the dividend, add it to 53, then carry on: 538 / 54

Step 5:
When dividing 538 by 54, we get 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 1699.0
Subtracting 486 from 538 leaves us with 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 54

Let's proceed to step 6:
If we divide 528 by 54, we get 9 and a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 16999.0
Subtracting 486 from 528 leaves us with 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 54

Let's proceed to step 7:
54 can be fit into 429 7 times, resulting in a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 169997.0
If we take 378 away from 429, we end up with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 54

On to step 8:
The number 54 fits into 519 9 times, leaving a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1699979.0
Subtract 486 from 519 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
330 divided by 54 is 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 1699979.6
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 54 fits into 60 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1699979.61
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
60 divided by 54 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1699979.611
Deduct 54 from 60 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 1699979.611 with a remaining 0.0006.
