485252 divided by 39 
The aim is to understand the frequency of 39 in 485252.

Going ahead to step 1:
If we divide 4 by 39, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 39

Let's proceed to step 2:
39 goes into 48 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 9 after subtracting 39 from 48.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 39

On to step 3:
When dividing 95 by 39, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 78 from 95, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 39

Going ahead to step 4:
39 goes into 172 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 124.0
If we subtract 156 from 172, we get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 39

Going ahead to step 5:
When dividing 165 by 39, we get 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 1244.0
The remainder is 9 after subtracting 156 from 165.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 39

Going ahead to step 6:
92 divided by 39 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 12442.0
If we take 78 away from 92, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 39, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 12442.3
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
When dividing 230 by 39, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 12442.35
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
39 can be fit into 350 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 12442.358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
39 can be fit into 380 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 12442.3589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
290 divided by 39 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 12442.35897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
When dividing 170 by 39, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 12442.358974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 12442.3589743
Subtract 117 from 140 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
39 goes into 230 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12442.35897435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 12442.35897435, and the remainder is 3.5e-08.
