68744 divided by 21 
We're looking to find how many times 21 goes into 68744.

On to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 21

On to step 2:
21 goes into 68 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 63 from 68 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 21

On to step 3:
The number 21 fits into 57 2 times, leaving a remainder of 15.
The next digit of our result is 2. 
Result so far: 32.0
If we subtract 42 from 57, we get 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 21

Going ahead to step 4:
The number 21 fits into 154 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 327.0
If we take 147 away from 154, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 21

Moving on to step 5:
If we divide 74 by 21, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3273.0
Deduct 63 from 74 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 6:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3273.5
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 21, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 3273.52
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3273.523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
If we divide 170 by 21, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 3273.5238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3273.5238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 21, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3273.523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3273.5238095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 3273.52380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 3273.52380952, and the remainder is 8e-09.
