966936 divided by 39 
The aim is to understand the frequency of 39 in 966936.

Going ahead to step 1:
39 goes into 9 0 times with 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.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 39

Moving on to step 2:
The number 39 fits into 96 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 78 away from 96, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 39

Moving on to step 3:
When dividing 186 by 39, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 156 away from 186, we end up with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 39

Let's proceed to step 4:
309 divided by 39 is 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 247.0
The remainder is 36 after subtracting 273 from 309.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 39

Let's proceed to step 5:
363 divided by 39 is 9 with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 2479.0
If we take 351 away from 363, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 39

Advancing to step 6:
126 divided by 39 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 24793.0
Subtracting 117 from 126 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 39 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 24793.2
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
When dividing 120 by 39, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 24793.23
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 39 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 24793.23
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
39 can be fit into 300 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 24793.2307
If we subtract 273 from 300, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
When dividing 270 by 39, we get 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 24793.23076
If we subtract 234 from 270, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
360 divided by 39 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 24793.230769
Deduct 351 from 360 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 24793.2307692
Deduct 78 from 90 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
120 divided by 39 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 24793.23076923
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 24793.23076923 with a remainder of 3e-09.
