Let's divide 124358 by 39
The aim is to understand the frequency of 39 in 124358.

Moving on to step 1:
1 divided by 39 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 39

Let's proceed to step 2:
39 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 39

Step 3:
If we divide 124 by 39, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 117 from 124 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 39

Let's proceed to step 4:
If we divide 73 by 39, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 39 from 73 to get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 39

Advancing to step 5:
The number 39 fits into 345 8 times, leaving a remainder of 33.
The next digit of our result is 8. 
Result so far: 318.0
If we subtract 312 from 345, we get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 39

Advancing to step 6:
If we divide 338 by 39, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 3188.0
If we take 312 away from 338, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
260 divided by 39 is 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 3188.6
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
39 goes into 260 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 3188.66
Deduct 234 from 260 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 3188.66 with a remainder of 0.026.
