We're dividing 406284 by 39 
The aim is to understand the frequency of 39 in 406284.

Moving on to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 39

Let's proceed to step 2:
39 can be fit into 40 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 39 from 40 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 39

Advancing to step 3:
39 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 39

Moving on to step 4:
The number 39 fits into 162 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtract 156 from 162 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 39

Going ahead to step 5:
39 can be fit into 68 1 times, resulting in a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1041.0
If we take 39 away from 68, we end up with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 39

Moving on to step 6:
294 divided by 39 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 10417.0
Subtracting 273 from 294 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.

Going ahead to step 7:
210 divided by 39 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10417.5
If we take 195 away from 210, we end up 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.

Moving on to step 8:
39 can be fit into 150 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 10417.53
Subtracting 117 from 150 leaves us 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.

Going ahead to step 9:
39 goes into 330 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 10417.538
If we subtract 312 from 330, we get 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 10:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 10417.5384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
39 goes into 240 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 10417.53846
Deduct 234 from 240 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.

On to step 12:
When dividing 60 by 39, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 10417.538461
If we take 39 away from 60, we end up 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 13:
210 divided by 39 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10417.5384615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
If we divide 150 by 39, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 10417.53846153
Subtract 117 from 150 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 10417.53846153, with a leftover of 3.3e-08.
