We're dividing 813823 by 53 
We want to divide 813823 by 53.

Going ahead 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

On to step 2:
When dividing 81 by 53, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 53 from 81 and we're left with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 53

Moving on to step 3:
283 divided by 53 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 265 from 283 and we're left with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 53

Going ahead to step 4:
When dividing 188 by 53, we get 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 29 after subtracting 159 from 188.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 53

Let's proceed to step 5:
If we divide 292 by 53, we get 5 and a remainder of 27.
The next digit of our result is 5. 
Result so far: 1535.0
If we take 265 away from 292, we end up with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 53

Going ahead to step 6:
53 goes into 273 5 times with a remainder of 8.
The next digit of our result is 5. 
Result so far: 15355.0
If we take 265 away from 273, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
53 goes into 80 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 15355.1
Subtract 53 from 80 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
53 goes into 270 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 15355.15
If we take 265 away from 270, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 53 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 15355.15
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 53 fits into 500 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 15355.1509
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
The number 53 fits into 230 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 15355.15094
If we take 212 away from 230, we end up 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.

Let's proceed to step 12:
180 divided by 53 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 15355.150943
The remainder is 21 after subtracting 159 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
53 can be fit into 210 3 times, resulting in a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 15355.1509433
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 15355.1509433, with a leftover of 5.1e-07.
