We're dividing 9133163 by 209 
The aim is to understand the frequency of 209 in 9133163.

Advancing to step 1:
9 divided by 209 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 209

Advancing to step 2:
The number 209 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (3) from the dividend, attach it to 91 and continue: 913 / 209

On to step 3:
209 goes into 913 4 times with a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 836 from 913 leaves us with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 209

Let's proceed to step 4:
The number 209 fits into 773 3 times, leaving a remainder of 146.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 146 after subtracting 627 from 773.
Include the next digit (1) from the dividend after 146, then repeat: 1461 / 209

Going ahead to step 5:
209 goes into 1461 6 times with a remainder of 207.
Put 6 as the next digit of the answer. 
Result so far: 436.0
Subtract 1254 from 1461 to get 207.
Include the next digit (6) from the dividend after 207, then repeat: 2076 / 209

Advancing to step 6:
2076 divided by 209 is 9 with a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 4369.0
Subtracting 1881 from 2076 leaves us with 195.
Fetch the next digit (3) from the dividend, attach it to 195 and continue: 1953 / 209

Let's proceed to step 7:
209 can be fit into 1953 9 times, resulting in a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 43699.0
The remainder is 72 after subtracting 1881 from 1953.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
When dividing 720 by 209, we get 3 with a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 43699.3
Subtracting 627 from 720 leaves us with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 9:
209 can be fit into 930 4 times, resulting in a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 43699.34
Subtracting 836 from 930 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
The number 209 fits into 940 4 times, leaving a remainder of 104.
The next digit of our result is 4. 
Result so far: 43699.344
Subtracting 836 from 940 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 43699.344, and the remainder is 0.0104.
