We're dividing 80131303 by 53 
Let's see how many times 53 fits into 80131303.

Going ahead to step 1:
8 divided by 53 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 53

Moving on to step 2:
53 goes into 80 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 53 away from 80, we end up with 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 53

Advancing to step 3:
The number 53 fits into 271 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 265 from 271, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 53

Let's proceed to step 4:
63 divided by 53 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtract 53 from 63 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 53

Let's proceed to step 5:
53 can be fit into 101 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
If we take 53 away from 101, we end up with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 53

Let's proceed to step 6:
53 goes into 483 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 15119.0
Subtracting 477 from 483 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 53

Step 7:
60 divided by 53 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 151191.0
If we take 53 away from 60, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 53

Step 8:
If we divide 73 by 53, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1511911.0
If we subtract 53 from 73, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 53, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 1511911.3
Subtract 159 from 200 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
53 goes into 410 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 1511911.37
Subtract 371 from 410 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
The number 53 fits into 390 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 1511911.377
Deduct 371 from 390 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 1511911.377 with a remaining 0.0019.
