Let's divide 624986 by 39
The aim is to understand the frequency of 39 in 624986.

Moving on to step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 39

Going ahead to step 2:
39 can be fit into 62 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 39 from 62 leaves us with 23.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 39

Step 3:
234 divided by 39 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 234 from 234 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 39

Moving on to step 4:
If we divide 9 by 39, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 160.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 39

Let's proceed to step 5:
The number 39 fits into 98 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 1602.0
If we subtract 78 from 98, we get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 39

Moving on to step 6:
The number 39 fits into 206 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 16025.0
Subtracting 195 from 206 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
If we divide 110 by 39, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 16025.2
If we take 78 away from 110, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
If we divide 320 by 39, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 16025.28
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
39 can be fit into 80 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 16025.282
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
When dividing 20 by 39, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16025.282
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 39 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 16025.28205
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
If we divide 50 by 39, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 16025.282051
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
110 divided by 39 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 16025.2820512
Subtract 78 from 110 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 39, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 16025.28205128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 16025.28205128 with a balance of 8e-09.
