78808433 divided by 53 
The aim is to understand the frequency of 53 in 78808433.

Let's proceed to step 1:
When dividing 7 by 53, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 53

Step 2:
When dividing 78 by 53, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 25 after subtracting 53 from 78.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 53

Advancing to step 3:
The number 53 fits into 258 4 times, leaving a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 46 after subtracting 212 from 258.
Fetch the next digit (0) from the dividend, attach it to 46 and continue: 460 / 53

Moving on to step 4:
If we divide 460 by 53, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 148.0
Subtracting 424 from 460 leaves us with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 53

On to step 5:
When dividing 368 by 53, we get 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 1486.0
The remainder is 50 after subtracting 318 from 368.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 53

On to step 6:
The number 53 fits into 504 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 14869.0
Deduct 477 from 504 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 53

Moving on to step 7:
The number 53 fits into 273 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 148695.0
If we subtract 265 from 273, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 53

Step 8:
The number 53 fits into 83 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1486951.0
If we take 53 away from 83, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 53 fits into 300 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1486951.5
Subtracting 265 from 300 leaves us 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.

Moving on to step 10:
When dividing 350 by 53, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1486951.56
If we subtract 318 from 350, we 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.

Moving on to step 11:
53 can be fit into 320 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 1486951.566
The remainder is 2 after subtracting 318 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 1486951.566, with a leftover of 0.0002.
