212353 divided by 12 
We want to figure out the number of times 212353 can be divided by 12.

Advancing to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 12

Step 2:
12 can be fit into 21 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 12 from 21 leaves us with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 12

Advancing to step 3:
The number 12 fits into 92 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 84 from 92 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 12

Going ahead to step 4:
12 goes into 83 6 times with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 176.0
The remainder is 11 after subtracting 72 from 83.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 12

Going ahead to step 5:
The number 12 fits into 115 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 1769.0
Subtract 108 from 115 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 12

Advancing to step 6:
73 divided by 12 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 17696.0
If we take 72 away from 73, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 12 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 17696.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 17696.08
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 17696.083
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 17696.0833
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 17696.0833, and the remainder is 4e-05.
