We're dividing 661503 by 36 
Our goal is to divide 661503 by 36.

On to step 1:
The number 36 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 36

Moving on to step 2:
When dividing 66 by 36, we get 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 36 from 66 to get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 36

Let's proceed to step 3:
When dividing 301 by 36, we get 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 288 away from 301, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 36

Moving on to step 4:
When dividing 135 by 36, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Subtracting 108 from 135 leaves us with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 36

Moving on to step 5:
36 can be fit into 270 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 1837.0
Deduct 252 from 270 and we're left with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 36

Step 6:
When dividing 183 by 36, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 18375.0
Subtracting 180 from 183 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 36, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 18375.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
36 goes into 300 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 18375.08
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 36 fits into 120 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 18375.083
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
36 can be fit into 120 3 times, resulting in a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 18375.0833
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 18375.0833 and a remainder of 0.00012.
