7452 ÷ 39 
The aim is to understand the frequency of 39 in 7452.

Step 1:
39 goes into 7 0 times with 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.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 39

Advancing to step 2:
39 goes into 74 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 39 from 74 and we're left with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 39

Let's proceed to step 3:
39 can be fit into 355 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 351 from 355 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 39

Going ahead to step 4:
42 divided by 39 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Deduct 39 from 42 and we're left with 3.
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 5:
30 divided by 39 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 191.0
Deduct 0 from 30 and we're left with 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 6:
39 goes into 300 7 times with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 191.07
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
39 goes into 270 6 times with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 191.076
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.

Let's proceed to step 8:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 191.0769
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.

Let's proceed to step 9:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 191.07692
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.

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: 191.076923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 39 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 191.076923
Deduct 0 from 30 and we're left with 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:
If we divide 300 by 39, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 191.07692307
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.

The final result is 191.07692307 with a remainder of 2.7e-08.
