837372 ÷ 54 
The aim is to understand the frequency of 54 in 837372.

Going ahead to step 1:
8 divided by 54 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 54

Moving on to step 2:
54 goes into 83 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 54 from 83, we get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 54

Moving on to step 3:
The number 54 fits into 297 5 times, leaving a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 270 from 297 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 54

Step 4:
273 divided by 54 is 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 155.0
Subtracting 270 from 273 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 54

Going ahead to step 5:
54 goes into 37 0 times with a remainder of 37.
The next digit of our result is 0. 
Result so far: 1550.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 54

Advancing to step 6:
54 can be fit into 372 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 15506.0
If we take 324 away from 372, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
54 can be fit into 480 8 times, resulting in a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 15506.8
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
480 divided by 54 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 15506.88
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 15506.88 and a remainder of 0.048.
