We look at the division of 372696 by 54 
The aim is to understand the frequency of 54 in 372696.

Going ahead to step 1:
54 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 54

Moving on to step 2:
When dividing 37 by 54, we get 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 54

Step 3:
54 goes into 372 6 times with a remainder of 48.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 48 after subtracting 324 from 372.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 54

Advancing to step 4:
When dividing 486 by 54, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 0 after subtracting 486 from 486.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 54

Moving on to step 5:
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: 690.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 54

Advancing to step 6:
When dividing 96 by 54, we get 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 6901.0
Deduct 54 from 96 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.

Going ahead to step 7:
If we divide 420 by 54, we get 7 and a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 6901.7
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.

Going ahead to step 8:
54 goes into 420 7 times with a remainder of 42.
The next digit of our result is 7. 
Result so far: 6901.77
Deduct 378 from 420 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.

Our division results in 6901.77 with a remaining 0.042.
