We're dividing 709949 by 21 
We want to divide 709949 by 21.

On to step 1:
7 divided by 21 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 21

Advancing to step 2:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 7 after subtracting 63 from 70.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 21

Moving on to step 3:
If we divide 79 by 21, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 63 from 79, we get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 21

Going ahead to step 4:
21 goes into 169 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 338.0
Subtract 168 from 169 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

Step 5:
21 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 3380.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 21

Moving on to step 6:
If we divide 149 by 21, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 33807.0
Deduct 147 from 149 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.

Going ahead to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 33807.0
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.

Going ahead to step 8:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 33807.09
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.

Advancing to step 9:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 33807.095
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.

Let's proceed to step 10:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 33807.0952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 21 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 33807.09523
If we subtract 63 from 80, we 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.

Let's proceed to step 12:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 33807.095238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
When dividing 20 by 21, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 33807.095238
If we take 0 away from 20, we end up 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 14:
If we divide 200 by 21, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 33807.09523809
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.

After the division, we end up with 33807.09523809 and a remainder of 1.1e-08.
