We look at the division of 607385 by 39 
The aim is to understand the frequency of 39 in 607385.

On to step 1:
When dividing 6 by 39, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 39

On to step 2:
39 goes into 60 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 21 after subtracting 39 from 60.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 39

Moving on to step 3:
217 divided by 39 is 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 195 away from 217, we end up with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 39

Going ahead to step 4:
39 goes into 223 5 times with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtract 195 from 223 to get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 39

Going ahead to step 5:
288 divided by 39 is 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1557.0
Subtract 273 from 288 to get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 39

Going ahead to step 6:
155 divided by 39 is 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 15573.0
Subtracting 117 from 155 leaves us 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.

Let's proceed to step 7:
If we divide 380 by 39, we get 9 and a remainder of 29.
The next digit of our result is 9. 
Result so far: 15573.9
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.

Step 8:
290 divided by 39 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 15573.97
Subtract 273 from 290 to 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.

On to step 9:
170 divided by 39 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 15573.974
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.

Advancing to step 10:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 15573.9743
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.

Let's proceed to step 11:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 15573.97435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
When dividing 350 by 39, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 15573.974358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
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: 15573.9743589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 14:
The number 39 fits into 290 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 15573.97435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 15573.97435897, with a leftover of 1.7e-08.
