2953838 divided by 39 
The aim is to understand the frequency of 39 in 2953838.

On to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 39

Let's proceed to step 2:
The number 39 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 39

Going ahead to step 3:
The number 39 fits into 295 7 times, leaving a remainder of 22.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 273 from 295 and we're left with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 39

Going ahead to step 4:
39 can be fit into 223 5 times, resulting in a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 28 after subtracting 195 from 223.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 39

Going ahead to step 5:
39 can be fit into 288 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 757.0
If we subtract 273 from 288, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 39

Advancing to step 6:
When dividing 153 by 39, we get 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 7573.0
The remainder is 36 after subtracting 117 from 153.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 39

On to step 7:
If we divide 368 by 39, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 75739.0
If we take 351 away from 368, 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.

On to step 8:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 75739.4
Subtract 156 from 170 to get 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:
When dividing 140 by 39, we get 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 75739.43
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 10:
39 can be fit into 230 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 75739.435
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 11:
39 can be fit into 350 8 times, resulting in a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 75739.4358
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 12:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 75739.43589
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.

Step 13:
39 can be fit into 290 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 75739.435897
If we subtract 273 from 290, we 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.

On to step 14:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 75739.4358974
Subtracting 156 from 170 leaves us 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.

Let's proceed to step 15:
When dividing 140 by 39, we get 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 75739.43589743
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.

The final result is 75739.43589743 with a remainder of 2.3e-08.
