We're dividing 792407 by 39 
The aim is to understand the frequency of 39 in 792407.

Step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 39

Let's proceed to step 2:
39 can be fit into 79 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 78 from 79.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 39

Step 3:
If we divide 12 by 39, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 39

Step 4:
39 goes into 124 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 203.0
Subtract 117 from 124 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 39

Let's proceed to step 5:
70 divided by 39 is 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 2031.0
If we take 39 away from 70, we end up with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 39

Let's proceed to step 6:
317 divided by 39 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 20318.0
Subtracting 312 from 317 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 20318.1
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
39 goes into 110 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 20318.12
Deduct 78 from 110 and we're left with 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 9:
39 goes into 320 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 20318.128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 39 fits into 80 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 20318.1282
Subtracting 78 from 80 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.

On to step 11:
39 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 20318.1282
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.

Let's proceed to step 12:
39 goes into 200 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 20318.128205
Subtracting 195 from 200 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
When dividing 50 by 39, we get 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 20318.1282051
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
110 divided by 39 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 20318.12820512
If we take 78 away from 110, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 20318.12820512 with a remainder of 3.2e-08.
