639224 divided by 54 
The aim is to understand the frequency of 54 in 639224.

Let's proceed to step 1:
54 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 54

Going ahead to step 2:
63 divided by 54 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 54 from 63 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 54

Step 3:
54 goes into 99 1 times with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 54 from 99 leaves us with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 54

Advancing to step 4:
If we divide 452 by 54, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 118.0
Subtract 432 from 452 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 54

Moving on to step 5:
The number 54 fits into 202 3 times, leaving a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 1183.0
Subtracting 162 from 202 leaves us with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 54

On to step 6:
When dividing 404 by 54, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 11837.0
If we take 378 away from 404, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 54 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 11837.4
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
When dividing 440 by 54, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11837.48
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
54 goes into 80 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 11837.481
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
If we divide 260 by 54, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11837.4814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
If we divide 440 by 54, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 11837.48148
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
54 can be fit into 80 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 11837.481481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
If we divide 260 by 54, we get 4 and a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 11837.4814814
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
54 can be fit into 440 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 11837.48148148
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 11837.48148148, and the remainder is 8e-09.
