We're dividing 88391 by 39 
The aim is to understand the frequency of 39 in 88391.

Advancing to step 1:
39 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 39

Step 2:
88 divided by 39 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 78 from 88 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 39

Going ahead to step 3:
If we divide 103 by 39, we get 2 and a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 78 from 103 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 39

Moving on to step 4:
If we divide 259 by 39, we get 6 and a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
The remainder is 25 after subtracting 234 from 259.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 39

On to step 5:
39 goes into 251 6 times with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 2266.0
If we take 234 away from 251, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 6:
When dividing 170 by 39, we get 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 2266.4
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 39 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 2266.43
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
If we divide 230 by 39, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2266.435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
The number 39 fits into 350 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 2266.4358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
39 goes into 380 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 2266.43589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2266.435897
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
If we divide 170 by 39, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 2266.4358974
If we subtract 156 from 170, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
39 goes into 140 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 2266.43589743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 2266.43589743 with a balance of 2.3e-08.
