We're dividing 638403 by 36 
We're looking to find how many times 36 goes into 638403.

Let's proceed to step 1:
If we divide 6 by 36, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 36

Moving on to step 2:
63 divided by 36 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 36 from 63 leaves us with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 36

Advancing to step 3:
If we divide 278 by 36, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 252 from 278 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 36

Let's proceed to step 4:
264 divided by 36 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we subtract 252 from 264, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 36

On to step 5:
36 can be fit into 120 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1773.0
The remainder is 12 after subtracting 108 from 120.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 36

Going ahead to step 6:
123 divided by 36 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 17733.0
If we take 108 away from 123, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 36 fits into 150 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 17733.4
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 36, we get 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 17733.41
Deduct 36 from 60 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
If we divide 240 by 36, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 17733.416
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
The number 36 fits into 240 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 17733.4166
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 17733.4166, and the remainder is 0.00024.
