80111015 divided by 852 
Our goal is to divide 80111015 by 852.

Moving on to step 1:
When dividing 8 by 852, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 852

Step 2:
852 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 852

On to step 3:
852 goes into 801 0 times with a remainder of 801.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 801 and we're left with 801.
Append the next digit (1) from the dividend to 801 and continue with: 8011 / 852

On to step 4:
852 can be fit into 8011 9 times, resulting in a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 7668 away from 8011, we end up with 343.
Fetch the next digit (1) from the dividend, attach it to 343 and continue: 3431 / 852

Going ahead to step 5:
When dividing 3431 by 852, we get 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 94.0
Subtracting 3408 from 3431 leaves us with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 852

Going ahead to step 6:
If we divide 230 by 852, we get 0 and a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 940.0
The remainder is 230 after subtracting 0 from 230.
Include the next digit (1) from the dividend after 230, then repeat: 2301 / 852

Going ahead to step 7:
If we divide 2301 by 852, we get 2 and a remainder of 597.
Put 2 as the next digit of the answer. 
Result so far: 9402.0
If we subtract 1704 from 2301, we get 597.
Bring next digit (5) of the dividend behind the 597 and repeat the process: 5975 / 852

Moving on to step 8:
The number 852 fits into 5975 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 94027.0
If we subtract 5964 from 5975, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
If we divide 110 by 852, we get 0 and a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 94027.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
If we divide 1100 by 852, we get 1 and a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 94027.01
If we subtract 852 from 1100, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 11:
The number 852 fits into 2480 2 times, leaving a remainder of 776.
The number 2 becomes the next digit in our result. 
Result so far: 94027.012
The remainder is 776 after subtracting 1704 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 12:
When dividing 7760 by 852, we get 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 94027.0129
If we take 7668 away from 7760, we end up 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.

Let's proceed to step 13:
852 can be fit into 920 1 times, resulting in a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 94027.01291
Subtract 852 from 920 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
680 divided by 852 is 0 with a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 94027.01291
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 15:
When dividing 6800 by 852, we get 7 with a remainder of 836.
The next digit of our result is 7. 
Result so far: 94027.0129107
Subtract 5964 from 6800 to get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Step 16:
8360 divided by 852 is 9 with a remainder of 692.
Record the quotient 9 as the next digit in the result. 
Result so far: 94027.01291079
Subtract 7668 from 8360 to get 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

After the division, we end up with 94027.01291079 and a remainder of 6.92e-07.
