We're dividing 726333 by 39 
The aim is to understand the frequency of 39 in 726333.

Going ahead to step 1:
If we divide 7 by 39, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 39

Step 2:
72 divided by 39 is 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 39 from 72, we get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 39

Moving on to step 3:
The number 39 fits into 336 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 24 after subtracting 312 from 336.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 39

Step 4:
243 divided by 39 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
If we subtract 234 from 243, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 39

Moving on to step 5:
The number 39 fits into 93 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 1862.0
If we take 78 away from 93, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 39

Going ahead to step 6:
If we divide 153 by 39, we get 3 and a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 18623.0
If we take 117 away from 153, we end up 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.

Step 7:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 18623.9
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.

Moving on to step 8:
When dividing 90 by 39, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 18623.92
Deduct 78 from 90 and we're left 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.

Let's proceed to step 9:
When dividing 120 by 39, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 18623.923
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 10:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 18623.923
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
When dividing 300 by 39, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 18623.92307
Subtract 273 from 300 to 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.

Moving on to step 12:
39 can be fit into 270 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 18623.923076
If we take 234 away from 270, we end up 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.

Going ahead to step 13:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 18623.9230769
Subtracting 351 from 360 leaves us 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.

Going ahead to step 14:
39 goes into 90 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 18623.92307692
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 18623.92307692 with a remaining 1.2e-08.
