256968 divided by 21 
We want to divide 256968 by 21.

Let's proceed to step 1:
21 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 21

Let's proceed to step 2:
25 divided by 21 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 21 from 25 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 21

Going ahead to step 3:
When dividing 46 by 21, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 4 after subtracting 42 from 46.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 21

Going ahead to step 4:
49 divided by 21 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 42 from 49 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 21

Going ahead to step 5:
76 divided by 21 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 1223.0
If we subtract 63 from 76, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 21

Let's proceed to step 6:
When dividing 138 by 21, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 12236.0
Deduct 126 from 138 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.

Moving on to step 7:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12236.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 12236.57
If we take 147 away from 150, we end up 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.

On to step 9:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 12236.571
Subtract 21 from 30 to 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.

Advancing to step 10:
90 divided by 21 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 12236.5714
If we take 84 away from 90, we end up with 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 11:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 12236.57142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 12236.571428
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.

Let's proceed to step 13:
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: 12236.5714285
Subtract 105 from 120 to get 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 14:
The number 21 fits into 150 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 12236.57142857
Deduct 147 from 150 and we're left 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.

After the division, we end up with 12236.57142857 and a remainder of 3e-09.
