Let's divide 87544451 by 54
The aim is to understand the frequency of 54 in 87544451.

Moving on to step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 54

Going ahead to step 2:
87 divided by 54 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 54 from 87 to get 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 54

Advancing to step 3:
If we divide 335 by 54, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 324 away from 335, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 54

Going ahead to step 4:
54 goes into 114 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we take 108 away from 114, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 54

Step 5:
If we divide 64 by 54, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1621.0
If we subtract 54 from 64, we get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 54

Step 6:
The number 54 fits into 104 1 times, leaving a remainder of 50.
The next digit of our result is 1. 
Result so far: 16211.0
Subtract 54 from 104 to get 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 54

Let's proceed to step 7:
505 divided by 54 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 162119.0
Deduct 486 from 505 and we're left with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 54

Going ahead to step 8:
54 goes into 191 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 1621193.0
Subtracting 162 from 191 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
The number 54 fits into 290 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1621193.5
Deduct 270 from 290 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
The number 54 fits into 200 3 times, leaving a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 1621193.53
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
54 can be fit into 380 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1621193.537
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
When dividing 20 by 54, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1621193.537
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
200 divided by 54 is 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 1621193.53703
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
380 divided by 54 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1621193.537037
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
If we divide 20 by 54, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1621193.537037
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
54 can be fit into 200 3 times, resulting in a remainder of 38.
The next digit of our result is 3. 
Result so far: 1621193.53703703
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 1621193.53703703 with a remainder of 3.8e-08.
