We look at the division of 9369399 by 332 
The aim is to understand the frequency of 332 in 9369399.

On to step 1:
332 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 332

Let's proceed to step 2:
332 goes into 93 0 times with a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 93 after subtracting 0 from 93.
Append the next digit (6) from the dividend to 93 and continue with: 936 / 332

On to step 3:
332 goes into 936 2 times with a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 664 from 936 to get 272.
Grab the next digit (9) from the dividend, add it to 272, then carry on: 2729 / 332

Going ahead to step 4:
332 goes into 2729 8 times with a remainder of 73.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 2656 from 2729 to get 73.
Fetch the next digit (3) from the dividend, attach it to 73 and continue: 733 / 332

Advancing to step 5:
The number 332 fits into 733 2 times, leaving a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 282.0
If we subtract 664 from 733, we get 69.
Fetch the next digit (9) from the dividend, attach it to 69 and continue: 699 / 332

Going ahead to step 6:
699 divided by 332 is 2 with a remainder of 35.
The next digit of our result is 2. 
Result so far: 2822.0
Subtract 664 from 699 to get 35.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 332

Let's proceed to step 7:
332 goes into 359 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 28221.0
The remainder is 27 after subtracting 332 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
270 divided by 332 is 0 with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 28221.0
If we subtract 0 from 270, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 9:
The number 332 fits into 2700 8 times, leaving a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 28221.08
Subtract 2656 from 2700 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
332 can be fit into 440 1 times, resulting in a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 28221.081
The remainder is 108 after subtracting 332 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
1080 divided by 332 is 3 with a remainder of 84.
The next digit of our result is 3. 
Result so far: 28221.0813
If we subtract 996 from 1080, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
332 goes into 840 2 times with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 28221.08132
Deduct 664 from 840 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
The number 332 fits into 1760 5 times, leaving a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 28221.081325
Subtract 1660 from 1760 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
1000 divided by 332 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 28221.0813253
If we subtract 996 from 1000, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 15:
332 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 28221.0813253
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 28221.0813253 and a remainder of 4e-08.
