We look at the division of 80455074 by 803 
We want to divide 80455074 by 803.

On to step 1:
When dividing 8 by 803, we get 0 with 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.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 803

Step 2:
80 divided by 803 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 803

Let's proceed to step 3:
If we divide 804 by 803, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 803 away from 804, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 803

Going ahead to step 4:
If we divide 15 by 803, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 15, we get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 803

Step 5:
803 can be fit into 155 0 times, resulting in a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 155, we end up with 155.
Bring next digit (0) of the dividend behind the 155 and repeat the process: 1550 / 803

Step 6:
When dividing 1550 by 803, we get 1 with a remainder of 747.
Use 1 as the next digit of our solution. 
Result so far: 1001.0
Deduct 803 from 1550 and we're left with 747.
Include the next digit (7) from the dividend after 747, then repeat: 7477 / 803

Advancing to step 7:
7477 divided by 803 is 9 with a remainder of 250.
Record the quotient 9 as the next digit in the result. 
Result so far: 10019.0
If we subtract 7227 from 7477, we get 250.
Include the next digit (4) from the dividend after 250, then repeat: 2504 / 803

Going ahead to step 8:
2504 divided by 803 is 3 with a remainder of 95.
Write down 3 as next digit of the result. 
Result so far: 100193.0
Subtract 2409 from 2504 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
803 goes into 950 1 times with a remainder of 147.
The next digit of our result is 1. 
Result so far: 100193.1
The remainder is 147 after subtracting 803 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 10:
When dividing 1470 by 803, we get 1 with a remainder of 667.
Put 1 as the next digit of the answer. 
Result so far: 100193.11
If we subtract 803 from 1470, we get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

The final result is 100193.11 with a remainder of 0.667.
