833257 ÷ 39 
The aim is to understand the frequency of 39 in 833257.

Step 1:
39 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 39

Moving on to step 2:
The number 39 fits into 83 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 78 from 83.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 39

Moving on to step 3:
The number 39 fits into 53 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 14 after subtracting 39 from 53.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 39

Moving on to step 4:
If we divide 142 by 39, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Deduct 117 from 142 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 39

Step 5:
255 divided by 39 is 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 2136.0
Subtracting 234 from 255 leaves us with 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 39

Step 6:
217 divided by 39 is 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 21365.0
The remainder is 22 after subtracting 195 from 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
220 divided by 39 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 21365.5
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.

Moving on to step 8:
When dividing 250 by 39, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 21365.56
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.

Step 9:
39 goes into 160 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 21365.564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
39 can be fit into 40 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21365.5641
Deduct 39 from 40 and we're left 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 11:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 21365.5641
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.

Let's proceed to step 12:
100 divided by 39 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 21365.564102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
39 can be fit into 220 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 21365.5641025
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.

Advancing to step 14:
If we divide 250 by 39, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 21365.56410256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 21365.56410256 with a remaining 1.6e-08.
