Let's divide 91004 by 53
The aim is to understand the frequency of 53 in 91004.

On to step 1:
The number 53 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 53

On to step 2:
53 can be fit into 91 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 53 from 91 to get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 53

Advancing to step 3:
380 divided by 53 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 371 from 380, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 53

On to step 4:
53 goes into 90 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 171.0
Subtract 53 from 90 to get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 53

Step 5:
The number 53 fits into 374 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1717.0
Subtracting 371 from 374 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
53 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1717.0
If we subtract 0 from 30, we 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.

On to step 7:
53 can be fit into 300 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1717.05
Deduct 265 from 300 and we're left 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.

Let's proceed to step 8:
53 goes into 350 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1717.056
Subtracting 318 from 350 leaves us with 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:
If we divide 320 by 53, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1717.0566
Subtracting 318 from 320 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.

After the division, we end up with 1717.0566 and a remainder of 2e-05.
