We're dividing 545077 by 21 
Let's see how many times 21 fits into 545077.

On to step 1:
21 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 21

Step 2:
If we divide 54 by 21, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 42 from 54 leaves us with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 21

Let's proceed to step 3:
The number 21 fits into 125 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 105 from 125 to get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 21

On to step 4:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 259.0
Subtract 189 from 200 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 21

On to step 5:
When dividing 117 by 21, we get 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 2595.0
Subtract 105 from 117 to get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 21

Going ahead to step 6:
When dividing 127 by 21, we get 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 25956.0
If we take 126 away from 127, we end up 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.

Advancing to step 7:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 25956.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 25956.04
Subtract 84 from 100 to 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.

Step 9:
21 goes into 160 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 25956.047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 25956.0476
Subtracting 126 from 130 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 11:
21 can be fit into 40 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 25956.04761
If we take 21 away from 40, we end up 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 12:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 25956.047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 25956.047619
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.

Moving on to step 14:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 25956.04761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 25956.04761904 with a balance of 1.6e-08.
