734353 ÷ 21 
Let's see how many times 21 fits into 734353.

On to step 1:
If we divide 7 by 21, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 21

Step 2:
The number 21 fits into 73 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
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

Let's proceed to step 3:
When dividing 104 by 21, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 84 from 104 leaves us with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 21

Let's proceed to step 4:
When dividing 203 by 21, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
Subtract 189 from 203 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 21

Let's proceed to step 5:
21 can be fit into 145 6 times, resulting in a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 3496.0
The remainder is 19 after subtracting 126 from 145.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 21

Step 6:
When dividing 193 by 21, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 34969.0
Deduct 189 from 193 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
21 goes into 40 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 34969.1
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 34969.19
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 21, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 34969.19
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 34969.1904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 21, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 34969.19047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 34969.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 34969.1904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
190 divided by 21 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 34969.19047619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 34969.19047619 with a balance of 1e-09.
