We're dividing 680649 by 39 
The aim is to understand the frequency of 39 in 680649.

Step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 39

Step 2:
68 divided by 39 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 39 from 68 to get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 39

Let's proceed to step 3:
39 goes into 290 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 273 away from 290, we end up with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 39

On to step 4:
The number 39 fits into 176 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 174.0
Subtract 156 from 176 to get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 39

Moving on to step 5:
The number 39 fits into 204 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 1745.0
If we subtract 195 from 204, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 39

Moving on to step 6:
39 goes into 99 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 17452.0
Subtract 78 from 99 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 39 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17452.5
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 17452.53
Deduct 117 from 150 and we're left 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.

Advancing to step 9:
39 goes into 330 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 17452.538
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:
180 divided by 39 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 17452.5384
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 17452.53846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
If we divide 60 by 39, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 17452.538461
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.

Step 13:
When dividing 210 by 39, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17452.5384615
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
When dividing 150 by 39, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 17452.53846153
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.

The final outcome is 17452.53846153, with a leftover of 3.3e-08.
