We look at the division of 750961 by 39 
The aim is to understand the frequency of 39 in 750961.

On to step 1:
39 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 39

Going ahead to step 2:
The number 39 fits into 75 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 39 from 75 leaves us with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 39

Advancing to step 3:
39 can be fit into 360 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 351 from 360 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 39

Advancing to step 4:
39 can be fit into 99 2 times, resulting in a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
If we take 78 away from 99, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 39

Step 5:
39 goes into 216 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 1925.0
If we take 195 away from 216, we end up with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 39

Moving on to step 6:
When dividing 211 by 39, we get 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 19255.0
Subtracting 195 from 211 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.

Let's proceed to step 7:
If we divide 160 by 39, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 19255.4
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.

Advancing to step 8:
When dividing 40 by 39, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 19255.41
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.

Advancing to step 9:
The number 39 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 19255.41
Subtract 0 from 10 to 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.

Advancing to step 10:
100 divided by 39 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 19255.4102
Subtracting 78 from 100 leaves us 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 11:
If we divide 220 by 39, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 19255.41025
The remainder is 25 after subtracting 195 from 220.
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 12:
The number 39 fits into 250 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 19255.410256
If we take 234 away from 250, we end up 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.

Let's proceed to step 13:
39 can be fit into 160 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 19255.4102564
If we take 156 away from 160, we end up 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.

Going ahead to step 14:
40 divided by 39 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 19255.41025641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 19255.41025641 with a balance of 1e-09.
