873422 ÷ 53 
The aim is to understand the frequency of 53 in 873422.

Moving on to step 1:
If we divide 8 by 53, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 53

Let's proceed to step 2:
53 goes into 87 1 times with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 53 from 87 leaves us with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 53

Let's proceed to step 3:
If we divide 343 by 53, we get 6 and a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 318 away from 343, we end up with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 53

Let's proceed to step 4:
The number 53 fits into 254 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we take 212 away from 254, we end up with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 53

Let's proceed to step 5:
53 goes into 422 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1647.0
If we subtract 371 from 422, we get 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 53

On to step 6:
If we divide 512 by 53, we get 9 and a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 16479.0
Subtract 477 from 512 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
When dividing 350 by 53, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 16479.6
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.

Going ahead to step 8:
53 can be fit into 320 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 16479.66
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.

After the division, we end up with 16479.66 and a remainder of 0.002.
