451503 ÷ 36 
Let's see how many times 36 fits into 451503.

Advancing to step 1:
36 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 36

Moving on to step 2:
If we divide 45 by 36, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 36 from 45.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 36

Step 3:
The number 36 fits into 91 2 times, leaving a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 72 from 91 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 36

Step 4:
36 goes into 195 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 180 from 195 leaves us with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 36

On to step 5:
The number 36 fits into 150 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 1254.0
If we take 144 away from 150, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 36

Moving on to step 6:
When dividing 63 by 36, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 12541.0
Subtract 36 from 63 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 36 fits into 270 7 times, leaving a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 12541.7
Deduct 252 from 270 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 36 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 12541.75
If we take 180 away from 180, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 36 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12541.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 36 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12541.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12541.75 with a remaining 0.0.
