665018 ÷ 39 
The aim is to understand the frequency of 39 in 665018.

Moving on to step 1:
39 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 39

Going ahead to step 2:
If we divide 66 by 39, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 39 from 66 to get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 39

Let's proceed to step 3:
If we divide 275 by 39, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 273 away from 275, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 39

Let's proceed to step 4:
20 divided by 39 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 170.0
If we take 0 away from 20, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 39

Going ahead to step 5:
When dividing 201 by 39, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 1705.0
Subtracting 195 from 201 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Step 6:
39 can be fit into 68 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 17051.0
If we take 39 away from 68, we end up 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 7:
290 divided by 39 is 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17051.7
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.

Advancing to step 8:
39 goes into 170 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 17051.74
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.

Going ahead to step 9:
If we divide 140 by 39, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 17051.743
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.

Step 10:
39 goes into 230 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 17051.7435
If we subtract 195 from 230, we get 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 11:
350 divided by 39 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 17051.74358
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 12:
When dividing 380 by 39, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 17051.743589
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.

Moving on to step 13:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 17051.7435897
Subtract 273 from 290 to get 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 14:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 17051.74358974
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.

In conclusion, the division gives 17051.74358974 with a balance of 1.4e-08.
