We're dividing 158279 by 39 
The aim is to understand the frequency of 39 in 158279.

On to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 39

Going ahead to step 2:
When dividing 15 by 39, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 39

Advancing to step 3:
When dividing 158 by 39, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 156 away from 158, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 39

On to step 4:
If we divide 22 by 39, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 39

On to step 5:
227 divided by 39 is 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 405.0
Subtract 195 from 227 to get 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 39

Step 6:
The number 39 fits into 329 8 times, leaving a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 4058.0
Deduct 312 from 329 and we're left 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.

Let's proceed to step 7:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4058.4
Subtract 156 from 170 to 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.

Advancing to step 8:
140 divided by 39 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 4058.43
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4058.435
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.

Moving on to step 10:
350 divided by 39 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 4058.4358
If we subtract 312 from 350, we get 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 11:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 4058.43589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
If we divide 290 by 39, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 4058.435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 13:
39 goes into 170 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4058.4358974
Deduct 156 from 170 and we're left with 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 14:
If we divide 140 by 39, we get 3 and a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 4058.43589743
If we subtract 117 from 140, we get 23.
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 4058.43589743 with a balance of 2.3e-08.
