911206 ÷ 53 
The aim is to understand the frequency of 53 in 911206.

Step 1:
When dividing 9 by 53, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 53

Advancing to step 2:
The number 53 fits into 91 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 38 after subtracting 53 from 91.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 53

Step 3:
53 goes into 381 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 10 after subtracting 371 from 381.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 53

Let's proceed to step 4:
53 goes into 102 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 171.0
Subtracting 53 from 102 leaves us with 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 53

Let's proceed to step 5:
If we divide 490 by 53, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1719.0
The remainder is 13 after subtracting 477 from 490.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 53

Let's proceed to step 6:
53 goes into 136 2 times with a remainder of 30.
The next digit of our result is 2. 
Result so far: 17192.0
Subtract 106 from 136 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 53 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 17192.5
If we take 265 away from 300, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
350 divided by 53 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 17192.56
Subtract 318 from 350 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
The number 53 fits into 320 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 17192.566
If we take 318 away from 320, we end up 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.

Our division results in 17192.566 with a remaining 0.0002.
