Let's divide 260134 by 21
Let's see how many times 21 fits into 260134.

On to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 21

Going ahead to step 2:
26 divided by 21 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 21 from 26 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 21

Advancing to step 3:
If we divide 50 by 21, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 8 after subtracting 42 from 50.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

On to step 4:
81 divided by 21 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 123.0
The remainder is 18 after subtracting 63 from 81.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 21

Advancing to step 5:
21 can be fit into 183 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 1238.0
The remainder is 15 after subtracting 168 from 183.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 21

Moving on to step 6:
21 goes into 154 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 12387.0
The remainder is 7 after subtracting 147 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 21 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 12387.3
If we subtract 63 from 70, 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.

Advancing to step 8:
The number 21 fits into 70 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 12387.33
If we take 63 away from 70, we end up 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.

In conclusion, the division gives 12387.33 with a balance of 0.007.
