86743950 ÷ 54 
The aim is to understand the frequency of 54 in 86743950.

Moving on to step 1:
When dividing 8 by 54, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 54

Moving on to step 2:
The number 54 fits into 86 1 times, leaving a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 54 from 86 and we're left with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 54

Let's proceed to step 3:
327 divided by 54 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 324 from 327, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 54

Let's proceed to step 4:
When dividing 34 by 54, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 54

Going ahead to step 5:
When dividing 343 by 54, we get 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 1606.0
Subtracting 324 from 343 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 54

On to step 6:
When dividing 199 by 54, we get 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 16063.0
The remainder is 37 after subtracting 162 from 199.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 54

Going ahead to step 7:
375 divided by 54 is 6 with a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 160636.0
The remainder is 51 after subtracting 324 from 375.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 54

Going ahead to step 8:
510 divided by 54 is 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 1606369.0
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
54 can be fit into 240 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 1606369.4
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
54 goes into 240 4 times with a remainder of 24.
The next digit of our result is 4. 
Result so far: 1606369.44
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1606369.44 and a remainder of 0.024.
