491149 ÷ 53 
The aim is to understand the frequency of 53 in 491149.

On to step 1:
If we divide 4 by 53, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 53

Moving on to step 2:
If we divide 49 by 53, we get 0 and a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 53

Moving on to step 3:
When dividing 491 by 53, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 477 away from 491, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 53

Let's proceed to step 4:
If we divide 141 by 53, we get 2 and a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtracting 106 from 141 leaves us with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 53

Let's proceed to step 5:
53 goes into 354 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 926.0
The remainder is 36 after subtracting 318 from 354.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 53

Step 6:
The number 53 fits into 369 6 times, leaving a remainder of 51.
The next digit of our result is 6. 
Result so far: 9266.0
Subtract 318 from 369 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
53 goes into 510 9 times with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 9266.9
Subtracting 477 from 510 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
53 goes into 330 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 9266.96
The remainder is 12 after subtracting 318 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 53 fits into 120 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 9266.962
If we take 106 away from 120, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
53 goes into 140 2 times with a remainder of 34.
The next digit of our result is 2. 
Result so far: 9266.9622
If we subtract 106 from 140, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 9266.9622 and a remainder of 0.00034.
