274474 divided by 21 
Let's see how many times 21 fits into 274474.

Step 1:
2 divided by 21 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Step 2:
27 divided by 21 is 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 21 away from 27, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 21

Moving on to step 3:
The number 21 fits into 64 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 63 from 64 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 21

Going ahead to step 4:
21 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 130.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 21

Advancing to step 5:
21 goes into 147 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1307.0
Subtract 147 from 147 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 21

On to step 6:
If we divide 4 by 21, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 13070.0
Subtracting 0 from 4 leaves us 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.

Moving on to step 7:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 13070.1
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
When dividing 190 by 21, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 13070.19
Deduct 189 from 190 and we're left 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.

Moving on to step 9:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 13070.19
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 13070.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
21 goes into 160 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 13070.19047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
When dividing 130 by 21, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 13070.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 13070.1904761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 13070.19047619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 13070.19047619 with a balance of 1e-09.
