We're dividing 260491 by 39 
The aim is to understand the frequency of 39 in 260491.

On to step 1:
39 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 39

Moving on to step 2:
26 divided by 39 is 0 with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 39

Let's proceed to step 3:
When dividing 260 by 39, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 234 from 260 to get 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 39

On to step 4:
39 can be fit into 264 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtracting 234 from 264 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 39

Let's proceed to step 5:
39 goes into 309 7 times with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 667.0
Deduct 273 from 309 and we're left with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 39

Step 6:
If we divide 361 by 39, we get 9 and a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 6679.0
If we subtract 351 from 361, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 39, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 6679.2
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
39 goes into 220 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6679.25
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
250 divided by 39 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 6679.256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 39, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 6679.2564
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 6679.25641
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
10 divided by 39 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6679.25641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 39, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 6679.2564102
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
220 divided by 39 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6679.25641025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 6679.25641025 with a remainder of 2.5e-08.
