Let's divide 664221 by 36
Our goal is to divide 664221 by 36.

Advancing to step 1:
The number 36 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 36

Let's proceed to step 2:
When dividing 66 by 36, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 36 from 66 and we're left with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 36

On to step 3:
When dividing 304 by 36, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we take 288 away from 304, we end up with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 36

Advancing to step 4:
36 can be fit into 162 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 184.0
If we take 144 away from 162, we end up with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 36

Step 5:
36 goes into 182 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 1845.0
Subtract 180 from 182 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 36

Moving on to step 6:
21 divided by 36 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 18450.0
Deduct 0 from 21 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
If we divide 210 by 36, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 18450.5
Deduct 180 from 210 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.

Step 8:
When dividing 300 by 36, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 18450.58
If we take 288 away from 300, we end up 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.

Let's proceed to step 9:
If we divide 120 by 36, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 18450.583
Subtracting 108 from 120 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.

Moving on to step 10:
36 goes into 120 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 18450.5833
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.

The quotient of the division is 18450.5833, and the remainder is 0.00012.
