490485 ÷ 39 
The aim is to understand the frequency of 39 in 490485.

Moving on to step 1:
39 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 39

Step 2:
39 can be fit into 49 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 39 from 49 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 39

Step 3:
39 goes into 100 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 78 away from 100, we end up with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 39

Going ahead to step 4:
The number 39 fits into 224 5 times, leaving a remainder of 29.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 29 after subtracting 195 from 224.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 39

Step 5:
The number 39 fits into 298 7 times, leaving a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 1257.0
Subtracting 273 from 298 leaves us with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 39

Advancing to step 6:
The number 39 fits into 255 6 times, leaving a remainder of 21.
The next digit of our result is 6. 
Result so far: 12576.0
The remainder is 21 after subtracting 234 from 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 39 fits into 210 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 12576.5
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 12576.53
Subtracting 117 from 150 leaves us 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 9:
39 can be fit into 330 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 12576.538
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 39 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 12576.5384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 12576.53846
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.

Let's proceed to step 12:
60 divided by 39 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 12576.538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12576.5384615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
150 divided by 39 is 3 with a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 12576.53846153
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.

In conclusion, the division gives 12576.53846153 with a balance of 3.3e-08.
