252217 ÷ 39 
The aim is to understand the frequency of 39 in 252217.

Moving on to step 1:
The number 39 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 39

Step 2:
When dividing 25 by 39, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 39

Step 3:
252 divided by 39 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 234 away from 252, we end up with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 39

Step 4:
If we divide 182 by 39, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 26 after subtracting 156 from 182.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 39

On to step 5:
39 can be fit into 261 6 times, resulting in a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 646.0
Subtract 234 from 261 to get 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 39

Going ahead to step 6:
If we divide 277 by 39, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 6467.0
The remainder is 4 after subtracting 273 from 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 39, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 6467.1
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 6467.1
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
39 goes into 100 2 times with a remainder of 22.
The next digit of our result is 2. 
Result so far: 6467.102
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
39 goes into 220 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6467.1025
Subtracting 195 from 220 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
The number 39 fits into 250 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 6467.10256
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
The number 39 fits into 160 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 6467.102564
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
39 can be fit into 40 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 6467.1025641
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
If we divide 10 by 39, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6467.1025641
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 6467.1025641 with a remainder of 1e-08.
