We look at the division of 74503 by 81 
We want to divide 74503 by 81.

Going ahead to step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 81

Moving on to step 2:
81 can be fit into 74 0 times, resulting in a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 81

Moving on to step 3:
When dividing 745 by 81, we get 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 729 from 745 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 81

Moving on to step 4:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 81 from 160 to get 79.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 81

On to step 5:
81 goes into 793 9 times with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 919.0
If we subtract 729 from 793, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 6:
81 goes into 640 7 times with a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 919.7
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
81 goes into 730 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 919.79
If we subtract 729 from 730, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
81 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 919.79
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 81, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 919.7901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 919.79012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
If we divide 280 by 81, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 919.790123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
When dividing 370 by 81, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 919.7901234
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 13:
81 can be fit into 460 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 919.79012345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 919.79012345 with a remaining 5.5e-08.
