Let's divide 754784 by 39
The aim is to understand the frequency of 39 in 754784.

Step 1:
39 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 39

On to step 2:
If we divide 75 by 39, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 39 from 75 to get 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 39

Moving on to step 3:
364 divided by 39 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 351 from 364, we get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 39

Moving on to step 4:
39 goes into 137 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 193.0
The remainder is 20 after subtracting 117 from 137.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 39

Advancing to step 5:
The number 39 fits into 208 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 1935.0
If we subtract 195 from 208, we get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 39

Let's proceed to step 6:
When dividing 134 by 39, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 19353.0
If we take 117 away from 134, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 39, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 19353.4
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.

Step 8:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 19353.43
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 19353.435
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 10:
39 goes into 350 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 19353.4358
If we subtract 312 from 350, we 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.

Let's proceed to step 11:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 19353.43589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
39 goes into 290 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 19353.435897
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.

On to step 13:
If we divide 170 by 39, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 19353.4358974
The remainder is 14 after subtracting 156 from 170.
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 14:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 19353.43589743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 19353.43589743 and a remainder of 2.3e-08.
