329815 ÷ 39 
The aim is to understand the frequency of 39 in 329815.

Going ahead to step 1:
3 divided by 39 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 39

On to step 2:
The number 39 fits into 32 0 times, leaving a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 39

Advancing to step 3:
39 can be fit into 329 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 312 away from 329, we end up with 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 39

Moving on to step 4:
39 goes into 178 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtract 156 from 178 to get 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 39

Going ahead to step 5:
39 goes into 221 5 times with a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 845.0
If we take 195 away from 221, we end up with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 39

Let's proceed to step 6:
When dividing 265 by 39, we get 6 with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 8456.0
The remainder is 31 after subtracting 234 from 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
310 divided by 39 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 8456.7
Deduct 273 from 310 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
39 goes into 370 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 8456.79
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
39 can be fit into 190 4 times, resulting in a remainder of 34.
The next digit of our result is 4. 
Result so far: 8456.794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
When dividing 340 by 39, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 8456.7948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
If we divide 280 by 39, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 8456.79487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
When dividing 70 by 39, we get 1 with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 8456.794871
If we subtract 39 from 70, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
39 goes into 310 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 8456.7948717
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 14:
If we divide 370 by 39, we get 9 and a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 8456.79487179
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 8456.79487179 with a balance of 1.9e-08.
