We divide 730365 by 21
Our goal is to divide 730365 by 21.

Step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 21

Step 2:
21 goes into 73 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 63 from 73 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 21

Going ahead to step 3:
If we divide 100 by 21, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 84 away from 100, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 21

Step 4:
21 goes into 163 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 347.0
Subtract 147 from 163 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 21

Going ahead to step 5:
When dividing 166 by 21, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 3477.0
Subtracting 147 from 166 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 21

Step 6:
If we divide 195 by 21, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 34779.0
Deduct 189 from 195 and we're left with 6.
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 7:
When dividing 60 by 21, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 34779.2
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
If we divide 180 by 21, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 34779.28
Subtract 168 from 180 to 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 9:
120 divided by 21 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 34779.285
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.

Step 10:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 34779.2857
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 34779.28571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 12:
When dividing 90 by 21, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 34779.285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 34779.2857142
Subtract 42 from 60 to get 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 14:
If we divide 180 by 21, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 34779.28571428
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.

After the division, we end up with 34779.28571428 and a remainder of 1.2e-08.
