209893 ÷ 12 
We're looking to find how many times 12 goes into 209893.

Let's proceed to step 1:
12 can be fit into 2 0 times, resulting in 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 (0) from the dividend, add it to 2, then carry on: 20 / 12

Advancing to step 2:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 12 from 20 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

Going ahead to step 3:
If we divide 89 by 12, we get 7 and a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 84 away from 89, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

Step 4:
The number 12 fits into 58 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
Deduct 48 from 58 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 12

Moving on to step 5:
12 can be fit into 109 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1749.0
Subtracting 108 from 109 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 12

Going ahead to step 6:
12 goes into 13 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 17491.0
If we take 12 away from 13, 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.

Step 7:
10 divided by 12 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 17491.0
If we take 0 away from 10, we end up 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:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 17491.08
If we take 96 away from 100, 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.

Step 9:
12 goes into 40 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 17491.083
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.

Moving on to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 17491.0833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 17491.0833 with a remaining 4e-05.
