We're dividing 636999 by 12 
We want to divide 636999 by 12.

Let's proceed to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 12

Advancing to step 2:
The number 12 fits into 63 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we take 60 away from 63, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 12

Let's proceed to step 3:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 53.0
The remainder is 0 after subtracting 36 from 36.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Step 4:
When dividing 9 by 12, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 530.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Going ahead to step 5:
12 can be fit into 99 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 5308.0
Deduct 96 from 99 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 12

Going ahead to step 6:
12 can be fit into 39 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 53083.0
If we take 36 away from 39, we end up 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.

On to step 7:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 53083.2
Subtract 24 from 30 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 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 53083.25
Subtracting 60 from 60 leaves us 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.

Let's proceed to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 53083.25
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.

Moving on to step 10:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53083.25
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.

The quotient of the division is 53083.25, and the remainder is 0.0.
