We look at the division of 709776 by 21 
We want to divide 709776 by 21.

Moving 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
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 21

Moving on to step 2:
When dividing 70 by 21, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 63 from 70 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 21

Step 3:
If we divide 79 by 21, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 16 after subtracting 63 from 79.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 21

Going ahead to step 4:
167 divided by 21 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 337.0
Subtract 147 from 167 to get 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 21

Let's proceed to step 5:
207 divided by 21 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 3379.0
If we subtract 189 from 207, we get 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 21

Let's proceed to step 6:
21 can be fit into 186 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 33798.0
Deduct 168 from 186 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 7:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33798.8
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.

Going ahead to step 8:
When dividing 120 by 21, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 33798.85
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
150 divided by 21 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 33798.857
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 10:
If we divide 30 by 21, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 33798.8571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 33798.85714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 21, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 33798.857142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
21 goes into 180 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33798.8571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
120 divided by 21 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 33798.85714285
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 33798.85714285 with a remainder of 1.5e-08.
