We're dividing 9357 by 43 
The aim is to understand the frequency of 43 in 9357.

Going ahead to step 1:
9 divided by 43 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 43

Advancing to step 2:
The number 43 fits into 93 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 7 after subtracting 86 from 93.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 43

On to step 3:
The number 43 fits into 75 1 times, leaving a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 43 from 75 leaves us with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 43

Moving on to step 4:
327 divided by 43 is 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 217.0
Subtracting 301 from 327 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 5:
If we divide 260 by 43, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 217.6
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
The number 43 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 217.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
The number 43 fits into 200 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 217.604
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
43 goes into 280 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 217.6046
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
The number 43 fits into 220 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 217.60465
If we take 215 away from 220, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 43, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 217.604651
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
70 divided by 43 is 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 217.6046511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 217.6046511 and a remainder of 2.7e-07.
