We divide 547401 by 21
We're looking to find how many times 21 goes into 547401.

Advancing to step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 21

On to step 2:
The number 21 fits into 54 2 times, leaving a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 42 away from 54, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 21

On to step 3:
21 can be fit into 127 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 1 after subtracting 126 from 127.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 21

On to step 4:
14 divided by 21 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
If we subtract 0 from 14, we get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 21

Let's proceed to step 5:
When dividing 140 by 21, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 2606.0
Subtract 126 from 140 to get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 21

On to step 6:
21 can be fit into 141 6 times, resulting in a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 26066.0
Deduct 126 from 141 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 26066.7
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 26066.71
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
If we divide 90 by 21, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 26066.714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 26066.7142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 26066.71428
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
If we divide 120 by 21, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 26066.714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 26066.7142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
30 divided by 21 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 26066.71428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 26066.71428571, and the remainder is 9e-09.
