408850 divided by 39 
The aim is to understand the frequency of 39 in 408850.

Let's proceed to step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 39

Let's proceed to step 2:
The number 39 fits into 40 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 40 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 39

Going ahead to step 3:
39 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 39

Advancing to step 4:
188 divided by 39 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtracting 156 from 188 leaves us with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 39

Moving on to step 5:
39 goes into 325 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 1048.0
Subtract 312 from 325 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 39

On to step 6:
When dividing 130 by 39, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 10483.0
Deduct 117 from 130 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 39 fits into 130 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 10483.3
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
When dividing 130 by 39, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 10483.33
Subtracting 117 from 130 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 10483.33 with a balance of 0.013.
