We look at the division of 816430 by 53 
We're looking to find how many times 53 goes into 816430.

Step 1:
The number 53 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 53

Going ahead to step 2:
53 goes into 81 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 53 from 81 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 53

Step 3:
The number 53 fits into 286 5 times, leaving a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 21 after subtracting 265 from 286.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 53

On to step 4:
53 goes into 214 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 154.0
Subtract 212 from 214 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 53

Moving on to step 5:
23 divided by 53 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 1540.0
If we subtract 0 from 23, we get 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 53

On to step 6:
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: 15404.0
Deduct 212 from 230 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
53 can be fit into 180 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 15404.3
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
53 goes into 210 3 times with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 15404.33
If we take 159 away from 210, we end up with 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 result is 15404.33 with a remainder of 0.051.
