733739 divided by 21 
We're looking to find how many times 21 goes into 733739.

Step 1:
21 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

On to step 2:
When dividing 73 by 21, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 63 from 73 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 21

Let's proceed to step 3:
103 divided by 21 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 84 from 103, we get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 21

Step 4:
21 goes into 197 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
Subtracting 189 from 197 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 21

Advancing to step 5:
83 divided by 21 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3493.0
Subtracting 63 from 83 leaves us with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 21

Let's proceed to step 6:
209 divided by 21 is 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 34939.0
If we subtract 189 from 209, 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.

Advancing to step 7:
200 divided by 21 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 34939.9
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.

Moving on to step 8:
The number 21 fits into 110 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 34939.95
Subtracting 105 from 110 leaves us 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 9:
21 goes into 50 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 34939.952
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 10:
21 can be fit into 80 3 times, resulting in a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 34939.9523
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 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 34939.95238
Subtract 168 from 170 to 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.

Going ahead to step 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 34939.95238
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.

Advancing to step 13:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 34939.9523809
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.

On to step 14:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 34939.95238095
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 quotient of the division is 34939.95238095, and the remainder is 5e-09.
