Let's divide 621113 by 53
The aim is to understand the frequency of 53 in 621113.

Going ahead to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 53

Advancing to step 2:
62 divided by 53 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 53 from 62, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 53

On to step 3:
53 can be fit into 91 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 53 from 91, we get 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 53

Let's proceed to step 4:
The number 53 fits into 381 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Deduct 371 from 381 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 53

Let's proceed to step 5:
If we divide 101 by 53, we get 1 and a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1171.0
The remainder is 48 after subtracting 53 from 101.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 53

Going ahead to step 6:
53 goes into 483 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 11719.0
Subtract 477 from 483 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 53, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 11719.1
Subtracting 53 from 60 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
53 goes into 70 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11719.11
Subtracting 53 from 70 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 11719.11, with a leftover of 0.017.
