We look at the division of 450369 by 36 
We want to divide 450369 by 36.

Moving on to step 1:
36 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 36

Going ahead to step 2:
When dividing 45 by 36, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 36 from 45 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 36

Step 3:
If we divide 90 by 36, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 72 from 90 and we're left with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 36

Going ahead to step 4:
The number 36 fits into 183 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 180 from 183 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 36

Moving on to step 5:
When dividing 36 by 36, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1251.0
Deduct 36 from 36 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 36

On to step 6:
The number 36 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 12510.0
Subtract 0 from 9 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 36, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 12510.2
Deduct 72 from 90 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.

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: 12510.25
The remainder is 0 after subtracting 180 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 36 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12510.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
36 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12510.25
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.

The final outcome is 12510.25, with a leftover of 0.0.
