We divide 250927 by 21
We want to divide 250927 by 21.

Step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 21

Advancing to step 2:
21 goes into 25 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 21 from 25 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 21

Advancing to step 3:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 19 after subtracting 21 from 40.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 21

On to step 4:
The number 21 fits into 199 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 189 from 199, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 21

On to step 5:
When dividing 102 by 21, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 1194.0
If we subtract 84 from 102, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 21

Advancing to step 6:
When dividing 187 by 21, we get 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 11948.0
If we subtract 168 from 187, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 11948.9
Subtract 189 from 190 to 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.

Going ahead to step 8:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 11948.9
If we take 0 away from 10, we end up 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.

Let's proceed to step 9:
100 divided by 21 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 11948.904
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.

Let's proceed to step 10:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 11948.9047
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 11:
The number 21 fits into 130 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 11948.90476
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.

Going ahead to step 12:
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: 11948.904761
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 13:
190 divided by 21 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 11948.9047619
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.

Advancing to step 14:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11948.9047619
If we take 0 away from 10, we end up 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.

The quotient of the division is 11948.9047619, and the remainder is 1e-08.
