We're dividing 647232 by 39 
The aim is to understand the frequency of 39 in 647232.

Step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 39

On to step 2:
64 divided by 39 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 39 from 64 and we're left with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 39

Moving on to step 3:
39 goes into 257 6 times with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 234 from 257, we get 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 39

Moving on to step 4:
39 can be fit into 232 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 165.0
If we subtract 195 from 232, we get 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 39

Moving on to step 5:
39 can be fit into 373 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 1659.0
If we subtract 351 from 373, we get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 39

On to step 6:
The number 39 fits into 222 5 times, leaving a remainder of 27.
The next digit of our result is 5. 
Result so far: 16595.0
If we subtract 195 from 222, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 39, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 16595.6
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
When dividing 360 by 39, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 16595.69
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
90 divided by 39 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 16595.692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 39 fits into 120 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 16595.6923
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
39 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 16595.6923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 39 is 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 16595.692307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
270 divided by 39 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 16595.6923076
Subtract 234 from 270 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
If we divide 360 by 39, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 16595.69230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 16595.69230769 with a remainder of 9e-09.
