We look at the division of 601515 by 39 
The aim is to understand the frequency of 39 in 601515.

Advancing to step 1:
39 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 39

Step 2:
When dividing 60 by 39, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 21 after subtracting 39 from 60.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 39

Moving on to step 3:
39 goes into 211 5 times with a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 195 from 211 to get 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 39

On to step 4:
When dividing 165 by 39, we get 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Deduct 156 from 165 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 39

Going ahead to step 5:
91 divided by 39 is 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 1542.0
Subtracting 78 from 91 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 39

Moving on to step 6:
When dividing 135 by 39, we get 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 15423.0
Subtracting 117 from 135 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
When dividing 180 by 39, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15423.4
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
39 goes into 240 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 15423.46
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.

Step 9:
When dividing 60 by 39, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 15423.461
If we subtract 39 from 60, we 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.

Let's proceed to step 10:
39 goes into 210 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15423.4615
The remainder is 15 after subtracting 195 from 210.
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 11:
The number 39 fits into 150 3 times, leaving a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 15423.46153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
330 divided by 39 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 15423.461538
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.

On to step 13:
39 can be fit into 180 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 15423.4615384
If we subtract 156 from 180, we get 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 14:
When dividing 240 by 39, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 15423.46153846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 15423.46153846, with a leftover of 6e-09.
