We're dividing 214900 by 21 
Our goal is to divide 214900 by 21.

Advancing to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 21

Let's proceed to step 2:
21 divided by 21 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 21 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 21

Advancing to step 3:
The number 21 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 21

On to step 4:
49 divided by 21 is 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 7 after subtracting 42 from 49.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 21

Going ahead to step 5:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1023.0
Deduct 63 from 70 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 21

On to step 6:
When dividing 70 by 21, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 10233.0
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 21, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10233.3
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
When dividing 70 by 21, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 10233.33
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 10233.33, with a leftover of 0.007.
