709736 ÷ 21 
Let's see how many times 21 fits into 709736.

Advancing to step 1:
7 divided by 21 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 21

Step 2:
The number 21 fits into 70 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 7 after subtracting 63 from 70.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 21

Let's proceed to step 3:
21 goes into 79 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
The remainder is 16 after subtracting 63 from 79.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 21

Let's proceed to step 4:
When dividing 167 by 21, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
Subtract 147 from 167 to get 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 21

Step 5:
The number 21 fits into 203 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 3379.0
If we take 189 away from 203, we end up with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 21

Advancing to step 6:
21 goes into 146 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 33796.0
Subtracting 126 from 146 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.

Advancing to step 7:
When dividing 200 by 21, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 33796.9
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.

Step 8:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 33796.95
Subtract 105 from 110 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.

Advancing to step 9:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 33796.952
Subtract 42 from 50 to 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.

Going ahead to step 10:
80 divided by 21 is 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 33796.9523
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.

Advancing to step 11:
170 divided by 21 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 33796.95238
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.

Advancing to step 12:
20 divided by 21 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 33796.95238
If we subtract 0 from 20, we get 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 13:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 33796.9523809
Deduct 189 from 200 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.

Going ahead to step 14:
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: 33796.95238095
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.

The final result is 33796.95238095 with a remainder of 5e-09.
