We divide 719730 by 21
Let's see how many times 21 fits into 719730.

Advancing to step 1:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 21

Moving on to step 2:
21 can be fit into 71 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 63 from 71 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 21

Moving on to step 3:
The number 21 fits into 89 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 84 from 89, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 21

Moving on to step 4:
The number 21 fits into 57 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtract 42 from 57 to get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 21

On to step 5:
153 divided by 21 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 3427.0
Subtract 147 from 153 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 21

Advancing to step 6:
60 divided by 21 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 34272.0
Deduct 42 from 60 and we're left with 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 7:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 34272.8
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.

Let's proceed to step 8:
The number 21 fits into 120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 34272.85
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
21 can be fit into 150 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 34272.857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 21, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 34272.8571
Subtracting 21 from 30 leaves us with 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 11:
If we divide 90 by 21, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 34272.85714
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.

Let's proceed to step 12:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 34272.857142
If we take 42 away from 60, we end up with 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 13:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 34272.8571428
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.

Let's proceed to step 14:
120 divided by 21 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 34272.85714285
If we take 105 away from 120, we end up 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.

The final outcome is 34272.85714285, with a leftover of 1.5e-08.
