824581 divided by 54 
The aim is to understand the frequency of 54 in 824581.

Advancing to step 1:
If we divide 8 by 54, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 54

Advancing to step 2:
The number 54 fits into 82 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 54 from 82 and we're left with 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 54

Advancing to step 3:
If we divide 284 by 54, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 270 from 284 leaves us with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 54

Advancing to step 4:
54 goes into 145 2 times with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we take 108 away from 145, we end up with 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 54

Step 5:
The number 54 fits into 378 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 1527.0
Subtract 378 from 378 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 54

Moving on to step 6:
When dividing 1 by 54, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 15270.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 54 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15270.0
Subtracting 0 from 10 leaves us 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 8:
54 goes into 100 1 times with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 15270.01
If we subtract 54 from 100, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
460 divided by 54 is 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 15270.018
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.

Step 10:
The number 54 fits into 280 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 15270.0185
Subtracting 270 from 280 leaves us 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.

On to step 11:
54 can be fit into 100 1 times, resulting in a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 15270.01851
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.

On to step 12:
54 goes into 460 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 15270.018518
Deduct 432 from 460 and we're left 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.

Let's proceed to step 13:
54 goes into 280 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15270.0185185
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 14:
54 can be fit into 100 1 times, resulting in a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 15270.01851851
Subtract 54 from 100 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 15270.01851851, and the remainder is 4.6e-08.
