501127 ÷ 21 
We want to divide 501127 by 21.

Advancing to step 1:
The number 21 fits into 5 0 times, leaving 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 (0) from the dividend to 5 and continue with: 50 / 21

Let's proceed to step 2:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 42 from 50 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 21

On to step 3:
When dividing 81 by 21, we get 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 63 from 81 to get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 21

Let's proceed to step 4:
21 goes into 181 8 times with a remainder of 13.
The next digit of our result is 8. 
Result so far: 238.0
The remainder is 13 after subtracting 168 from 181.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 21

Step 5:
When dividing 132 by 21, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 2386.0
Deduct 126 from 132 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Let's proceed to step 6:
If we divide 67 by 21, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 23863.0
If we take 63 away from 67, we end up 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.

On to step 7:
When dividing 40 by 21, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 23863.1
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.

Step 8:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 23863.19
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.

Moving on to step 9:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 23863.19
Subtract 0 from 10 to get 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 10:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 23863.1904
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:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 23863.19047
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:
If we divide 130 by 21, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 23863.190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
21 goes into 40 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 23863.1904761
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.

Step 14:
190 divided by 21 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 23863.19047619
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.

Our division results in 23863.19047619 with a remaining 1e-09.
