365697 ÷ 39 
The aim is to understand the frequency of 39 in 365697.

On to step 1:
3 divided by 39 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 39

Let's proceed to step 2:
36 divided by 39 is 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 39

On to step 3:
If we divide 365 by 39, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 351 from 365 and we're left with 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 39

Step 4:
The number 39 fits into 146 3 times, leaving a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
The remainder is 29 after subtracting 117 from 146.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 39

Moving on to step 5:
39 can be fit into 299 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 937.0
Deduct 273 from 299 and we're left with 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 39

Step 6:
39 can be fit into 267 6 times, resulting in a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 9376.0
Subtract 234 from 267 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
If we divide 330 by 39, we get 8 and a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 9376.8
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
180 divided by 39 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 9376.84
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 9376.846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 39, we get 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 9376.8461
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
210 divided by 39 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 9376.84615
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 9376.846153
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
39 goes into 330 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 9376.8461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
When dividing 180 by 39, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 9376.84615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 9376.84615384, with a leftover of 2.4e-08.
