700580 divided by 54 
The aim is to understand the frequency of 54 in 700580.

Moving on to step 1:
54 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 54

Let's proceed to step 2:
When dividing 70 by 54, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 54 from 70, we get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 54

Advancing to step 3:
If we divide 160 by 54, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 108 away from 160, we end up with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 54

On to step 4:
If we divide 525 by 54, we get 9 and a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 39 after subtracting 486 from 525.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 54

Step 5:
When dividing 398 by 54, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 1297.0
The remainder is 20 after subtracting 378 from 398.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 54

Advancing to step 6:
When dividing 200 by 54, we get 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 12973.0
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.

Advancing to step 7:
The number 54 fits into 380 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 12973.7
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.

Advancing to step 8:
54 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12973.7
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.

Step 9:
200 divided by 54 is 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 12973.703
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.

Step 10:
If we divide 380 by 54, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 12973.7037
Subtracting 378 from 380 leaves us 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.

Step 11:
When dividing 20 by 54, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12973.7037
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.

Let's proceed to step 12:
The number 54 fits into 200 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 12973.703703
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.

Let's proceed to step 13:
If we divide 380 by 54, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 12973.7037037
The remainder is 2 after subtracting 378 from 380.
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 14:
20 divided by 54 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12973.7037037
Subtracting 0 from 20 leaves us 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.

The final outcome is 12973.7037037, with a leftover of 2e-08.
