We divide 636153 by 54
The aim is to understand the frequency of 54 in 636153.

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 (3) from the dividend, add it to 6, then carry on: 63 / 54

Advancing to step 2:
54 goes into 63 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 54 from 63 to get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 54

Advancing to step 3:
96 divided by 54 is 1 with a remainder of 42.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 54 from 96 leaves us with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 54

On to step 4:
54 goes into 421 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 117.0
Subtracting 378 from 421 leaves us with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 54

Moving on to step 5:
The number 54 fits into 435 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 1178.0
Subtract 432 from 435 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 54

Advancing to step 6:
If we divide 33 by 54, we get 0 and a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 11780.0
If we take 0 away from 33, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
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: 11780.6
Deduct 324 from 330 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.

Going ahead to step 8:
60 divided by 54 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 11780.61
Subtract 54 from 60 to 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.

On to step 9:
When dividing 60 by 54, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 11780.611
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.

The final outcome is 11780.611, with a leftover of 0.0006.
