Let's divide 631419 by 12
We're looking to find how many times 12 goes into 631419.

Advancing to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Going ahead to step 2:
If we divide 63 by 12, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 60 from 63, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 12

Advancing to step 3:
If we divide 31 by 12, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtract 24 from 31 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 12

On to step 4:
74 divided by 12 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 526.0
If we take 72 away from 74, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 12

Advancing to step 5:
When dividing 21 by 12, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 5261.0
If we subtract 12 from 21, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 12

Let's proceed to step 6:
99 divided by 12 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 52618.0
If we subtract 96 from 99, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 12 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 52618.2
If we take 24 away from 30, we end up with 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.
Write down 5 as next digit of the result. 
Result so far: 52618.25
If we subtract 60 from 60, 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.

Advancing to step 9:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52618.25
Subtracting 0 from 0 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.

On to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52618.25
Deduct 0 from 0 and we're left 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 52618.25 with a remaining 0.0.
