We're dividing 125807 by 54 
The aim is to understand the frequency of 54 in 125807.

Moving on to step 1:
The number 54 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 54

Step 2:
54 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 54

On to step 3:
54 goes into 125 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 108 from 125, we get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 54

Advancing to step 4:
54 goes into 178 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 162 from 178, we get 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 54

Let's proceed to step 5:
54 goes into 160 2 times with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
Deduct 108 from 160 and we're left with 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 54

Let's proceed to step 6:
When dividing 527 by 54, we get 9 with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 2329.0
If we subtract 486 from 527, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
54 goes into 410 7 times with a remainder of 32.
The next digit of our result is 7. 
Result so far: 2329.7
The remainder is 32 after subtracting 378 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
The number 54 fits into 320 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2329.75
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
When dividing 500 by 54, we get 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 2329.759
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
When dividing 140 by 54, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2329.7592
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
54 goes into 320 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2329.75925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
When dividing 500 by 54, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 2329.759259
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
If we divide 140 by 54, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 2329.7592592
The remainder is 32 after subtracting 108 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
320 divided by 54 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 2329.75925925
The remainder is 50 after subtracting 270 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 2329.75925925 with a remaining 5e-08.
