We look at the division of 30309896 by 936 
The aim is to understand the frequency of 936 in 30309896.

Going ahead to step 1:
The number 936 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 936

On to step 2:
936 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 936

Going ahead to step 3:
303 divided by 936 is 0 with a remainder of 303.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 303 and we're left with 303.
Include the next digit (0) from the dividend after 303, then repeat: 3030 / 936

On to step 4:
When dividing 3030 by 936, we get 3 with a remainder of 222.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2808 from 3030 leaves us with 222.
Fetch the next digit (9) from the dividend, attach it to 222 and continue: 2229 / 936

Let's proceed to step 5:
936 can be fit into 2229 2 times, resulting in a remainder of 357.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 1872 away from 2229, we end up with 357.
Grab the next digit (8) from the dividend, add it to 357, then carry on: 3578 / 936

Moving on to step 6:
3578 divided by 936 is 3 with a remainder of 770.
Write down 3 as next digit of the result. 
Result so far: 323.0
If we take 2808 away from 3578, we end up with 770.
Fetch the next digit (9) from the dividend, attach it to 770 and continue: 7709 / 936

Let's proceed to step 7:
When dividing 7709 by 936, we get 8 with a remainder of 221.
The next digit of our result is 8. 
Result so far: 3238.0
Deduct 7488 from 7709 and we're left with 221.
Fetch the next digit (6) from the dividend, attach it to 221 and continue: 2216 / 936

Step 8:
The number 936 fits into 2216 2 times, leaving a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 32382.0
If we take 1872 away from 2216, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 9:
If we divide 3440 by 936, we get 3 and a remainder of 632.
Record the quotient 3 as the next digit in the result. 
Result so far: 32382.3
The remainder is 632 after subtracting 2808 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 10:
When dividing 6320 by 936, we get 6 with a remainder of 704.
Put 6 as the next digit of the answer. 
Result so far: 32382.36
If we subtract 5616 from 6320, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Step 11:
The number 936 fits into 7040 7 times, leaving a remainder of 488.
Write down 7 as next digit of the result. 
Result so far: 32382.367
Deduct 6552 from 7040 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 12:
If we divide 4880 by 936, we get 5 and a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 32382.3675
If we subtract 4680 from 4880, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
936 goes into 2000 2 times with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 32382.36752
Subtracting 1872 from 2000 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 14:
936 can be fit into 1280 1 times, resulting in a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 32382.367521
Subtract 936 from 1280 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 15:
When dividing 3440 by 936, we get 3 with a remainder of 632.
The number 3 becomes the next digit in our result. 
Result so far: 32382.3675213
Subtract 2808 from 3440 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 16:
936 can be fit into 6320 6 times, resulting in a remainder of 704.
Use 6 as the next digit of our solution. 
Result so far: 32382.36752136
If we take 5616 away from 6320, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

After the division, we end up with 32382.36752136 and a remainder of 7.04e-07.
