734393 ÷ 21 
We want to divide 734393 by 21.

On to step 1:
21 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 21

On to step 2:
21 can be fit into 73 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 63 away from 73, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 21

Moving on to step 3:
104 divided by 21 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 84 from 104 leaves us with 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 21

Advancing to step 4:
The number 21 fits into 203 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 349.0
Deduct 189 from 203 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 21

Moving on to step 5:
If we divide 149 by 21, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 3497.0
Subtract 147 from 149 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 21

Step 6:
If we divide 23 by 21, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 34971.0
If we take 21 away from 23, we end up 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.

On to step 7:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 34971.0
Deduct 0 from 20 and we're left 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.

On to step 8:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 34971.09
Subtracting 189 from 200 leaves us 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.

On to step 9:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 34971.095
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.
Write down 2 as next digit of the result. 
Result so far: 34971.0952
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.

Going ahead to step 11:
The number 21 fits into 80 3 times, leaving a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 34971.09523
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.

Let's proceed to step 12:
If we divide 170 by 21, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 34971.095238
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.

Let's proceed to step 13:
21 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 34971.095238
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.

On to step 14:
When dividing 200 by 21, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 34971.09523809
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.

The final result is 34971.09523809 with a remainder of 1.1e-08.
