We look at the division of 764247 by 39 
The aim is to understand the frequency of 39 in 764247.

Step 1:
7 divided by 39 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 39

Step 2:
The number 39 fits into 76 1 times, leaving a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 37 after subtracting 39 from 76.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 39

Advancing to step 3:
If we divide 374 by 39, we get 9 and a remainder of 23.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 351 from 374 leaves us with 23.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 39

Let's proceed to step 4:
39 can be fit into 232 5 times, resulting in a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 195.0
If we subtract 195 from 232, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 39

Let's proceed to step 5:
The number 39 fits into 374 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 1959.0
Subtracting 351 from 374 leaves us with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 39

Let's proceed to step 6:
39 can be fit into 237 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 19596.0
The remainder is 3 after subtracting 234 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 39, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 19596.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 39, we get 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 19596.07
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
If we divide 270 by 39, we get 6 and a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 19596.076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 10:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 19596.0769
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
If we divide 90 by 39, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 19596.07692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 19596.076923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 19596.076923
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
39 can be fit into 300 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 19596.07692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 19596.07692307, with a leftover of 2.7e-08.
