768625 ÷ 54 
The aim is to understand the frequency of 54 in 768625.

Let's proceed to step 1:
If we divide 7 by 54, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 54

Moving on to step 2:
When dividing 76 by 54, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 22 after subtracting 54 from 76.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 54

On to step 3:
54 goes into 228 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 216 from 228 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 54

Going ahead to step 4:
54 goes into 126 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we subtract 108 from 126, we get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 54

Advancing to step 5:
54 goes into 182 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1423.0
Subtract 162 from 182 to get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 54

Going ahead to step 6:
When dividing 205 by 54, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 14233.0
If we take 162 away from 205, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
If we divide 430 by 54, we get 7 and a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 14233.7
Deduct 378 from 430 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
520 divided by 54 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 14233.79
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
340 divided by 54 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 14233.796
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
54 goes into 160 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 14233.7962
If we take 108 away from 160, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
54 goes into 520 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 14233.79629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
The number 54 fits into 340 6 times, leaving a remainder of 16.
The next digit of our result is 6. 
Result so far: 14233.796296
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 54 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 14233.7962962
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
54 goes into 520 9 times with a remainder of 34.
The next digit of our result is 9. 
Result so far: 14233.79629629
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 14233.79629629 with a balance of 3.4e-08.
