We look at the division of 719259 by 21 
We're looking to find how many times 21 goes into 719259.

Let's proceed to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
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

Step 2:
21 goes into 71 3 times with a remainder of 8.
The number 3 becomes the next digit in our 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

On to step 3:
21 can be fit into 89 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 84 from 89 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 21

Step 4:
52 divided by 21 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Deduct 42 from 52 and we're left with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 21

On to step 5:
If we divide 105 by 21, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3425.0
If we take 105 away from 105, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 21

Let's proceed to step 6:
If we divide 9 by 21, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 34250.0
If we take 0 away from 9, we end up 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.

On to step 7:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 34250.4
Deduct 84 from 90 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.

Step 8:
21 goes into 60 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 34250.42
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
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: 34250.428
Subtracting 168 from 180 leaves us 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.

On to step 10:
If we divide 120 by 21, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 34250.4285
Deduct 105 from 120 and we're left 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 11:
150 divided by 21 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 34250.42857
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.

On to step 12:
30 divided by 21 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 34250.428571
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.

Advancing to step 13:
If we divide 90 by 21, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 34250.4285714
Subtracting 84 from 90 leaves us 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.

On to step 14:
If we divide 60 by 21, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 34250.42857142
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.

The quotient of the division is 34250.42857142, and the remainder is 1.8e-08.
