We look at the division of 61791 by 54 
The aim is to understand the frequency of 54 in 61791.

Going ahead to step 1:
When dividing 6 by 54, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 54

On to step 2:
If we divide 61 by 54, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 54 from 61 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 54

On to step 3:
The number 54 fits into 77 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 54 from 77 leaves us with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 54

Moving on to step 4:
The number 54 fits into 239 4 times, leaving a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 216 away from 239, we end up with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 54

Step 5:
When dividing 231 by 54, we get 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 1144.0
Subtracting 216 from 231 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
150 divided by 54 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 1144.2
Deduct 108 from 150 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
54 can be fit into 420 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 1144.27
The remainder is 42 after subtracting 378 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
54 can be fit into 420 7 times, resulting in a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 1144.277
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 1144.277 with a balance of 0.0042.
