We're dividing 900602 by 39 
The aim is to understand the frequency of 39 in 900602.

Going ahead to step 1:
If we divide 9 by 39, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 39

Moving on to step 2:
The number 39 fits into 90 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 12 after subtracting 78 from 90.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 39

Let's proceed to step 3:
120 divided by 39 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 117 from 120 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 39

Going ahead to step 4:
36 divided by 39 is 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 230.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 39

Moving on to step 5:
The number 39 fits into 360 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2309.0
Subtracting 351 from 360 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 39

On to step 6:
39 goes into 92 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 23092.0
Subtracting 78 from 92 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.

Advancing to step 7:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23092.3
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 8:
When dividing 230 by 39, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 23092.35
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.

On to step 9:
350 divided by 39 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 23092.358
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.

Going ahead to step 10:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 23092.3589
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.

Moving on to step 11:
39 can be fit into 290 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 23092.35897
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.

Let's proceed to step 12:
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: 23092.358974
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.

Moving on to step 13:
The number 39 fits into 140 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 23092.3589743
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.

Step 14:
If we divide 230 by 39, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 23092.35897435
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.

The final outcome is 23092.35897435, with a leftover of 3.5e-08.
