We look at the division of 229138 by 21 
We want to divide 229138 by 21.

Let's proceed to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

On to step 2:
22 divided by 21 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 21 from 22.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 21

Going ahead to step 3:
If we divide 19 by 21, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 19, we get 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 21

On to step 4:
When dividing 191 by 21, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we subtract 189 from 191, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 21

Let's proceed to step 5:
23 divided by 21 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1091.0
Subtracting 21 from 23 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 21

Moving on to step 6:
21 can be fit into 28 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 10911.0
If we subtract 21 from 28, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
21 goes into 70 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10911.3
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.

Going ahead to step 8:
When dividing 70 by 21, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 10911.33
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.

After the division, we end up with 10911.33 and a remainder of 0.007.
