Let's divide 815397 by 53
Our goal is to divide 815397 by 53.

Moving on to step 1:
53 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 53

Moving on to step 2:
If we divide 81 by 53, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 53 from 81 and we're left with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 53

Step 3:
If we divide 285 by 53, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 265 from 285, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 53

Step 4:
53 can be fit into 203 3 times, resulting in a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 159 from 203 to get 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 53

Moving on to step 5:
53 goes into 449 8 times with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 1538.0
If we subtract 424 from 449, we get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 53

Going ahead to step 6:
When dividing 257 by 53, we get 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 15384.0
Subtract 212 from 257 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
53 can be fit into 450 8 times, resulting in a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 15384.8
Subtracting 424 from 450 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
53 can be fit into 260 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 15384.84
The remainder is 48 after subtracting 212 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
The number 53 fits into 480 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 15384.849
Deduct 477 from 480 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
53 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 15384.849
If we subtract 0 from 30, we get 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 11:
If we divide 300 by 53, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 15384.84905
The remainder is 35 after subtracting 265 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 12:
53 goes into 350 6 times with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 15384.849056
If we take 318 away from 350, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
53 goes into 320 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 15384.8490566
Deduct 318 from 320 and we're left 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.

The quotient of the division is 15384.8490566, and the remainder is 2e-08.
