We're dividing 256017 by 39 
The aim is to understand the frequency of 39 in 256017.

Going ahead to step 1:
39 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 39

On to step 2:
39 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 39

On to step 3:
When dividing 256 by 39, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 234 from 256 to get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 39

Step 4:
39 can be fit into 220 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtract 195 from 220 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 39

Advancing to step 5:
39 can be fit into 251 6 times, resulting in a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 656.0
If we subtract 234 from 251, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 39

Advancing to step 6:
If we divide 177 by 39, we get 4 and a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 6564.0
Subtract 156 from 177 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
210 divided by 39 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 6564.5
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 39, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 6564.53
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
When dividing 330 by 39, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 6564.538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
39 can be fit into 180 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 6564.5384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 39, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6564.53846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 6564.538461
Deduct 39 from 60 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
If we divide 210 by 39, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6564.5384615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 6564.53846153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 6564.53846153, with a leftover of 3.3e-08.
