Let's divide 909398 by 39
The aim is to understand the frequency of 39 in 909398.

Step 1:
The number 39 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 39

Moving on to step 2:
If we divide 90 by 39, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 78 from 90 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 39

Let's proceed to step 3:
The number 39 fits into 129 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 117 from 129 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 39

Let's proceed to step 4:
The number 39 fits into 123 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 233.0
If we take 117 away from 123, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 39

Advancing to step 5:
39 can be fit into 69 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 2331.0
Subtract 39 from 69 to get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 39

Moving on to step 6:
The number 39 fits into 308 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 23317.0
If we take 273 away from 308, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 39 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 23317.8
If we take 312 away from 350, we end up with 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 8:
When dividing 380 by 39, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 23317.89
If we subtract 351 from 380, we 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.

On to step 9:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 23317.897
If we take 273 away from 290, 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.

Step 10:
170 divided by 39 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 23317.8974
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.

Step 11:
If we divide 140 by 39, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23317.89743
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.

Advancing to step 12:
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: 23317.897435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
39 can be fit into 350 8 times, resulting in a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 23317.8974358
Deduct 312 from 350 and we're left with 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 14:
When dividing 380 by 39, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 23317.89743589
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 23317.89743589, and the remainder is 2.9e-08.
