We look at the division of 274946 by 21 
We're looking to find how many times 21 goes into 274946.

Advancing to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 21

Let's proceed to step 2:
21 can be fit into 27 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 21 from 27.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 21

On to step 3:
If we divide 64 by 21, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 63 from 64 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 21

Step 4:
19 divided by 21 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 21

On to step 5:
The number 21 fits into 194 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1309.0
The remainder is 5 after subtracting 189 from 194.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 21

Let's proceed to step 6:
56 divided by 21 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 13092.0
If we take 42 away from 56, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
21 goes into 140 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 13092.6
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
The number 21 fits into 140 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 13092.66
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 13092.66, with a leftover of 0.014.
