Let's divide 648503 by 45
We want to divide 648503 by 45.

Moving on to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 45

Advancing to step 2:
64 divided by 45 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 64 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 45

Advancing to step 3:
The number 45 fits into 198 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 180 away from 198, we end up with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 45

Step 4:
When dividing 185 by 45, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 144.0
The remainder is 5 after subtracting 180 from 185.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 45

Moving on to step 5:
If we divide 50 by 45, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1441.0
Deduct 45 from 50 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 45

Let's proceed to step 6:
45 can be fit into 53 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 14411.0
If we subtract 45 from 53, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
80 divided by 45 is 1 with a remainder of 35.
The next digit of our result is 1. 
Result so far: 14411.1
If we subtract 45 from 80, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
45 goes into 350 7 times with a remainder of 35.
The next digit of our result is 7. 
Result so far: 14411.17
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 14411.177
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 14411.177 and a remainder of 0.0035.
