We divide 717848 by 21
Let's see how many times 21 fits into 717848.

On to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 21

Moving on to step 2:
The number 21 fits into 71 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 8 after subtracting 63 from 71.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 21

Moving on to step 3:
21 goes into 87 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 3 after subtracting 84 from 87.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 21

Advancing to step 4:
38 divided by 21 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 341.0
The remainder is 17 after subtracting 21 from 38.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 21

Advancing to step 5:
21 goes into 174 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 3418.0
The remainder is 6 after subtracting 168 from 174.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 21

Step 6:
When dividing 68 by 21, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 34183.0
Subtract 63 from 68 to 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.

Moving on to step 7:
21 goes into 50 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 34183.2
Deduct 42 from 50 and we're left 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.

Moving on to step 8:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 34183.23
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 34183.238
If we subtract 168 from 170, we get 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:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 34183.238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 34183.23809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
When dividing 110 by 21, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 34183.238095
Deduct 105 from 110 and we're left 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.

On to step 13:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 34183.2380952
Subtracting 42 from 50 leaves us 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.

On to step 14:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 34183.23809523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The quotient of the division is 34183.23809523, and the remainder is 1.7e-08.
