79142 divided by 39 
The aim is to understand the frequency of 39 in 79142.

Going ahead to step 1:
The number 39 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 39

Moving on to step 2:
79 divided by 39 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 78 away from 79, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 39

Advancing to step 3:
The number 39 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 39

Let's proceed to step 4:
When dividing 114 by 39, we get 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we subtract 78 from 114, we get 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 39

On to step 5:
When dividing 362 by 39, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2029.0
Subtract 351 from 362 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 6:
When dividing 110 by 39, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2029.2
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
39 can be fit into 320 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 2029.28
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 39, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2029.282
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
39 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2029.282
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
When dividing 200 by 39, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2029.28205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 39 fits into 50 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2029.282051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
39 can be fit into 110 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 2029.2820512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
39 goes into 320 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 2029.28205128
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 2029.28205128 with a remainder of 8e-09.
