290080 ÷ 39 
The aim is to understand the frequency of 39 in 290080.

Going ahead to step 1:
39 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 39

Moving on to step 2:
39 can be fit into 29 0 times, resulting in a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 39

Advancing to step 3:
When dividing 290 by 39, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 273 from 290 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 39

Let's proceed to step 4:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 74.0
If we subtract 156 from 170, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 39

Going ahead to step 5:
When dividing 148 by 39, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 743.0
The remainder is 31 after subtracting 117 from 148.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 39

Advancing to step 6:
When dividing 310 by 39, we get 7 with a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 7437.0
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.

Going ahead to step 7:
370 divided by 39 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 7437.9
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.

Let's proceed to step 8:
If we divide 190 by 39, we get 4 and a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 7437.94
If we take 156 away from 190, we end up 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 9:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 7437.948
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
280 divided by 39 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 7437.9487
Deduct 273 from 280 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
39 can be fit into 70 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 7437.94871
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.

Advancing to step 12:
When dividing 310 by 39, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 7437.948717
The remainder is 37 after subtracting 273 from 310.
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 13:
The number 39 fits into 370 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 7437.9487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
190 divided by 39 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 7437.94871794
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 7437.94871794 with a balance of 3.4e-08.
