We look at the division of 814716 by 39 
The aim is to understand the frequency of 39 in 814716.

Let's proceed to step 1:
If we divide 8 by 39, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 39

Advancing to step 2:
39 goes into 81 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 78 away from 81, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 39

Advancing to step 3:
39 goes into 34 0 times with a remainder of 34.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 34 to get 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 39

Going ahead to step 4:
When dividing 347 by 39, we get 8 with a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
If we take 312 away from 347, we end up with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 39

Going ahead to step 5:
If we divide 351 by 39, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 2089.0
If we subtract 351 from 351, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 39

Moving on to step 6:
39 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 20890.0
Deduct 0 from 6 and we're left with 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 7:
If we divide 60 by 39, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 20890.1
Subtracting 39 from 60 leaves us 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 8:
39 goes into 210 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 20890.15
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.

On to step 9:
150 divided by 39 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 20890.153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
39 goes into 330 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 20890.1538
Deduct 312 from 330 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 20890.15384
If we take 156 away from 180, we end up 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.

Going ahead to step 12:
39 goes into 240 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 20890.153846
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.

Let's proceed to step 13:
39 goes into 60 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 20890.1538461
The remainder is 21 after subtracting 39 from 60.
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 14:
The number 39 fits into 210 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 20890.15384615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 20890.15384615 with a balance of 1.5e-08.
