We divide 803144 by 53
Let's see how many times 53 fits into 803144.

Advancing to 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 53

Moving on to step 2:
53 goes into 80 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 27 after subtracting 53 from 80.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 53

Moving on to step 3:
When dividing 273 by 53, we get 5 with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 265 from 273 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 53

Going ahead to step 4:
When dividing 81 by 53, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 151.0
Deduct 53 from 81 and we're left with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 53

On to step 5:
53 can be fit into 284 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 1515.0
Subtracting 265 from 284 leaves us with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 53

Moving on to step 6:
53 can be fit into 194 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 15153.0
The remainder is 35 after subtracting 159 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
350 divided by 53 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 15153.6
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.

Going ahead to step 8:
53 can be fit into 320 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 15153.66
Subtract 318 from 320 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 15153.66 and a remainder of 0.002.
