We divide 803318 by 53
The aim is to understand the frequency of 53 in 803318.

Step 1:
8 divided by 53 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 53

Going ahead to step 2:
When dividing 80 by 53, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 53 from 80 to get 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 53

Going ahead to step 3:
When dividing 273 by 53, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 265 away from 273, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 53

Advancing to step 4:
If we divide 83 by 53, we get 1 and a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
Subtract 53 from 83 to get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 53

Step 5:
301 divided by 53 is 5 with a remainder of 36.
The number 5 becomes the next digit in our result. 
Result so far: 1515.0
The remainder is 36 after subtracting 265 from 301.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 53

Let's proceed to step 6:
53 goes into 368 6 times with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 15156.0
Subtracting 318 from 368 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
If we divide 500 by 53, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 15156.9
Subtract 477 from 500 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
53 can be fit into 230 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 15156.94
The remainder is 18 after subtracting 212 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
If we divide 180 by 53, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 15156.943
Subtracting 159 from 180 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
53 goes into 210 3 times with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 15156.9433
If we subtract 159 from 210, we 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.

The final outcome is 15156.9433, with a leftover of 0.00051.
