We look at the division of 759565 by 54 
The aim is to understand the frequency of 54 in 759565.

Let's proceed to step 1:
When dividing 7 by 54, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 54

On to step 2:
54 goes into 75 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 54 from 75, we get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 54

Going ahead to step 3:
54 can be fit into 219 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 216 from 219 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 54

Advancing to step 4:
35 divided by 54 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
If we subtract 0 from 35, we get 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 54

Going ahead to step 5:
If we divide 356 by 54, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1406.0
The remainder is 32 after subtracting 324 from 356.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 54

Moving on to step 6:
The number 54 fits into 325 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 14066.0
Deduct 324 from 325 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
54 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 14066.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 54 fits into 100 1 times, leaving a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 14066.01
If we take 54 away from 100, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
54 goes into 460 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 14066.018
If we subtract 432 from 460, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
54 can be fit into 280 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 14066.0185
Deduct 270 from 280 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 54 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 14066.01851
Deduct 54 from 100 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
The number 54 fits into 460 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 14066.018518
Subtracting 432 from 460 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 54 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 14066.0185185
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
54 goes into 100 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 14066.01851851
Deduct 54 from 100 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 14066.01851851 and a remainder of 4.6e-08.
