We look at the division of 80263604 by 531 
We want to divide 80263604 by 531.

Advancing to step 1:
8 divided by 531 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 531

Let's proceed to step 2:
531 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 531

Advancing to step 3:
531 can be fit into 802 1 times, resulting in a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 531 from 802 leaves us with 271.
Include the next digit (6) from the dividend after 271, then repeat: 2716 / 531

Going ahead to step 4:
If we divide 2716 by 531, we get 5 and a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 2655 from 2716 and we're left with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 531

Moving on to step 5:
When dividing 613 by 531, we get 1 with a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we subtract 531 from 613, we get 82.
Include the next digit (6) from the dividend after 82, then repeat: 826 / 531

Step 6:
531 can be fit into 826 1 times, resulting in a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 1511.0
The remainder is 295 after subtracting 531 from 826.
Grab the next digit (0) from the dividend, add it to 295, then carry on: 2950 / 531

On to step 7:
The number 531 fits into 2950 5 times, leaving a remainder of 295.
The next digit of our result is 5. 
Result so far: 15115.0
If we subtract 2655 from 2950, we get 295.
Append the next digit (4) from the dividend to 295 and continue with: 2954 / 531

Step 8:
The number 531 fits into 2954 5 times, leaving a remainder of 299.
The number 5 becomes the next digit in our result. 
Result so far: 151155.0
If we take 2655 away from 2954, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 9:
2990 divided by 531 is 5 with a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 151155.5
Subtracting 2655 from 2990 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 10:
531 can be fit into 3350 6 times, resulting in a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 151155.56
Subtract 3186 from 3350 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
531 goes into 1640 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 151155.563
Deduct 1593 from 1640 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
531 can be fit into 470 0 times, resulting in a remainder of 470.
Put 0 as the next digit of the answer. 
Result so far: 151155.563
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 13:
531 can be fit into 4700 8 times, resulting in a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 151155.56308
Deduct 4248 from 4700 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 14:
If we divide 4520 by 531, we get 8 and a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 151155.563088
If we take 4248 away from 4520, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Our division results in 151155.563088 with a remaining 2.72e-05.
