We're dividing 900201 by 12 
We're looking to find how many times 12 goes into 900201.

On to step 1:
12 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 12

Let's proceed to step 2:
12 goes into 90 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 84 away from 90, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

Step 3:
When dividing 60 by 12, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 60 from 60 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 12

On to step 4:
12 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 750.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 12

On to step 5:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 7501.0
If we take 12 away from 20, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 12

Moving on to step 6:
81 divided by 12 is 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 75016.0
If we subtract 72 from 81, we 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.

On to step 7:
90 divided by 12 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 75016.7
If we subtract 84 from 90, we 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.

Step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 75016.75
If we take 60 away from 60, 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.

Advancing to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 75016.75
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.

Moving on to step 10:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 75016.75
If we take 0 away from 0, 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.

Our division results in 75016.75 with a remaining 0.0.
