We look at the division of 80447703 by 253 
Our goal is to divide 80447703 by 253.

Step 1:
The number 253 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 253

Step 2:
253 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 253

On to step 3:
253 goes into 804 3 times with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 759 away from 804, we end up with 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 253

Advancing to step 4:
The number 253 fits into 454 1 times, leaving a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 253 from 454, we get 201.
Fetch the next digit (7) from the dividend, attach it to 201 and continue: 2017 / 253

Step 5:
2017 divided by 253 is 7 with a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 317.0
The remainder is 246 after subtracting 1771 from 2017.
Append the next digit (7) from the dividend to 246 and continue with: 2467 / 253

On to step 6:
2467 divided by 253 is 9 with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 3179.0
The remainder is 190 after subtracting 2277 from 2467.
Include the next digit (0) from the dividend after 190, then repeat: 1900 / 253

Let's proceed to step 7:
When dividing 1900 by 253, we get 7 with a remainder of 129.
The next digit of our result is 7. 
Result so far: 31797.0
The remainder is 129 after subtracting 1771 from 1900.
Grab the next digit (3) from the dividend, add it to 129, then carry on: 1293 / 253

Moving on to step 8:
253 goes into 1293 5 times with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 317975.0
Subtracting 1265 from 1293 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
The number 253 fits into 280 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 317975.1
The remainder is 27 after subtracting 253 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
If we divide 270 by 253, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 317975.11
If we take 253 away from 270, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 317975.11 with a remainder of 0.017.
