We're dividing 80171209 by 538 
Our goal is to divide 80171209 by 538.

Going ahead to step 1:
8 divided by 538 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 538

Advancing to step 2:
When dividing 80 by 538, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 538

Advancing to step 3:
801 divided by 538 is 1 with a remainder of 263.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 538 from 801, we get 263.
Include the next digit (7) from the dividend after 263, then repeat: 2637 / 538

Step 4:
2637 divided by 538 is 4 with a remainder of 485.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 2152 away from 2637, we end up with 485.
Grab the next digit (1) from the dividend, add it to 485, then carry on: 4851 / 538

Going ahead to step 5:
When dividing 4851 by 538, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 149.0
If we take 4842 away from 4851, we end up with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 538

Let's proceed to step 6:
538 can be fit into 92 0 times, resulting in a remainder of 92.
The next digit of our result is 0. 
Result so far: 1490.0
Subtract 0 from 92 to get 92.
Take the next digit (0) from the dividend and append it to 92, then repeat: 920 / 538

On to step 7:
538 can be fit into 920 1 times, resulting in a remainder of 382.
Put 1 as the next digit of the answer. 
Result so far: 14901.0
Subtract 538 from 920 to get 382.
Bring next digit (9) of the dividend behind the 382 and repeat the process: 3829 / 538

Moving on to step 8:
538 goes into 3829 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 149017.0
The remainder is 63 after subtracting 3766 from 3829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
If we divide 630 by 538, we get 1 and a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 149017.1
Subtracting 538 from 630 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
When dividing 920 by 538, we get 1 with a remainder of 382.
Record the quotient 1 as the next digit in the result. 
Result so far: 149017.11
Deduct 538 from 920 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

The final result is 149017.11 with a remainder of 0.382.
