Let's divide 58978 by 39
The aim is to understand the frequency of 39 in 58978.

Moving on to step 1:
39 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 39

Moving on to step 2:
58 divided by 39 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 39 from 58 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 39

Going ahead to step 3:
The number 39 fits into 199 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 195 from 199 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 39

Step 4:
The number 39 fits into 47 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we subtract 39 from 47, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 39

Moving on to step 5:
39 can be fit into 88 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 1512.0
The remainder is 10 after subtracting 78 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
If we divide 100 by 39, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 1512.2
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 39, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1512.25
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1512.256
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 39 fits into 160 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1512.2564
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
39 goes into 40 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1512.25641
Subtracting 39 from 40 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
When dividing 10 by 39, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1512.25641
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
The number 39 fits into 100 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1512.2564102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
If we divide 220 by 39, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1512.25641025
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 1512.25641025 with a remaining 2.5e-08.
