We divide 233159 by 39
The aim is to understand the frequency of 39 in 233159.

Let's proceed to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 39

On to step 2:
39 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 39

Moving on to step 3:
If we divide 233 by 39, we get 5 and a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 195 from 233 leaves us with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 39

Step 4:
39 can be fit into 381 9 times, resulting in a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Deduct 351 from 381 and we're left with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 39

Step 5:
The number 39 fits into 305 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 597.0
Subtract 273 from 305 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 39

Moving on to step 6:
39 can be fit into 329 8 times, resulting in a remainder of 17.
The next digit of our result is 8. 
Result so far: 5978.0
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.

Going ahead to step 7:
39 goes into 170 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 5978.4
Subtracting 156 from 170 leaves us 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.

On to step 8:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 5978.43
Subtracting 117 from 140 leaves us 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.

Let's proceed to step 9:
39 goes into 230 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5978.435
Deduct 195 from 230 and we're left 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.

On to step 10:
350 divided by 39 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 5978.4358
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.

On to step 11:
If we divide 380 by 39, we get 9 and a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 5978.43589
Deduct 351 from 380 and we're left 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.

Going ahead to step 12:
39 can be fit into 290 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 5978.435897
If we take 273 away from 290, 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 13:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 5978.4358974
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.

Let's proceed 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: 5978.43589743
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.

The final outcome is 5978.43589743, with a leftover of 2.3e-08.
