We look at the division of 59639025 by 54 
The aim is to understand the frequency of 54 in 59639025.

On to step 1:
If we divide 5 by 54, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 54

On to step 2:
59 divided by 54 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 5 after subtracting 54 from 59.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 54

Step 3:
56 divided by 54 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 54 from 56, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 54

Going ahead to step 4:
23 divided by 54 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
Subtract 0 from 23 to get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 54

Moving on to step 5:
239 divided by 54 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 1104.0
If we subtract 216 from 239, we get 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 54

Advancing to step 6:
The number 54 fits into 230 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 11044.0
Subtract 216 from 230 to get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 54

Advancing to step 7:
54 can be fit into 142 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 110442.0
If we subtract 108 from 142, we get 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 54

Step 8:
54 goes into 345 6 times with a remainder of 21.
The next digit of our result is 6. 
Result so far: 1104426.0
The remainder is 21 after subtracting 324 from 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 54, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 1104426.3
Deduct 162 from 210 and we're left 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 10:
480 divided by 54 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 1104426.38
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.

Going ahead to step 11:
480 divided by 54 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 1104426.388
Deduct 432 from 480 and we're left 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 1104426.388 and a remainder of 0.0048.
