73504171 divided by 485 
Our goal is to divide 73504171 by 485.

Step 1:
485 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 485

Going ahead to step 2:
The number 485 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 485

Moving on to step 3:
485 can be fit into 735 1 times, resulting in a remainder of 250.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 485 from 735, we get 250.
Fetch the next digit (0) from the dividend, attach it to 250 and continue: 2500 / 485

On to step 4:
485 goes into 2500 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 2425 away from 2500, we end up with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 485

Moving on to step 5:
754 divided by 485 is 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Deduct 485 from 754 and we're left with 269.
Append the next digit (1) from the dividend to 269 and continue with: 2691 / 485

On to step 6:
The number 485 fits into 2691 5 times, leaving a remainder of 266.
Use 5 as the next digit of our solution. 
Result so far: 1515.0
Subtract 2425 from 2691 to get 266.
Append the next digit (7) from the dividend to 266 and continue with: 2667 / 485

Advancing to step 7:
485 goes into 2667 5 times with a remainder of 242.
The next digit of our result is 5. 
Result so far: 15155.0
The remainder is 242 after subtracting 2425 from 2667.
Fetch the next digit (1) from the dividend, attach it to 242 and continue: 2421 / 485

On to step 8:
2421 divided by 485 is 4 with a remainder of 481.
Put 4 as the next digit of the answer. 
Result so far: 151554.0
If we subtract 1940 from 2421, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 9:
4810 divided by 485 is 9 with a remainder of 445.
The number 9 becomes the next digit in our result. 
Result so far: 151554.9
Subtracting 4365 from 4810 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 10:
The number 485 fits into 4450 9 times, leaving a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 151554.99
If we subtract 4365 from 4450, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The quotient of the division is 151554.99, and the remainder is 0.085.
