Let's divide 266401 by 12
Our goal is to divide 266401 by 12.

On to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 12

On to step 2:
12 can be fit into 26 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 24 from 26 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 12

Going ahead to step 3:
If we divide 26 by 12, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 12

Going ahead to step 4:
12 goes into 24 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 222.0
Subtract 24 from 24 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 12

Moving on to step 5:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2220.0
If we subtract 0 from 0, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 12

Advancing to step 6:
If we divide 1 by 12, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 22200.0
Subtracting 0 from 1 leaves us 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.

On to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 22200.0
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.

Going ahead to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 22200.08
Subtracting 96 from 100 leaves us 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.

Let's proceed to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 22200.083
Subtract 36 from 40 to 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.

Let's proceed to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 22200.0833
Deduct 36 from 40 and we're left 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 final outcome is 22200.0833, with a leftover of 4e-05.
