790481 divided by 39 
The aim is to understand the frequency of 39 in 790481.

Let's proceed to step 1:
If we divide 7 by 39, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 39

Going ahead to step 2:
39 goes into 79 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 78 from 79, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 39

Moving on to step 3:
10 divided by 39 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 39

Let's proceed to step 4:
39 can be fit into 104 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 202.0
Deduct 78 from 104 and we're left with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 39

Moving on to step 5:
268 divided by 39 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 2026.0
Deduct 234 from 268 and we're left with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 39

Going ahead to step 6:
The number 39 fits into 341 8 times, leaving a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 20268.0
The remainder is 29 after subtracting 312 from 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
When dividing 290 by 39, we get 7 with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 20268.7
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.

Moving on to step 8:
When dividing 170 by 39, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 20268.74
If we take 156 away from 170, we end up with 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:
39 can be fit into 140 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 20268.743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
The number 39 fits into 230 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 20268.7435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
If we divide 350 by 39, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 20268.74358
Subtract 312 from 350 to 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:
39 goes into 380 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 20268.743589
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.

On to step 13:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 20268.7435897
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.

Moving on to step 14:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 20268.74358974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 20268.74358974, with a leftover of 1.4e-08.
