We look at the division of 732730 by 21 
We want to figure out the number of times 732730 can be divided by 21.

Advancing to step 1:
21 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

Moving on to step 2:
When dividing 73 by 21, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 63 from 73 leaves us with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 21

On to step 3:
The number 21 fits into 102 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 84 from 102, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 21

Advancing to step 4:
When dividing 187 by 21, we get 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 348.0
If we take 168 away from 187, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 21

Moving on to step 5:
When dividing 193 by 21, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 3489.0
Subtracting 189 from 193 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 21

Advancing to step 6:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 34891.0
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 7:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 34891.9
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 34891.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 34891.904
If we take 84 away from 100, we end up 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.

Let's proceed to step 10:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 34891.9047
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
21 can be fit into 130 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 34891.90476
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.

On to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 34891.904761
Subtract 21 from 40 to 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.

Moving on to step 13:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 34891.9047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 34891.9047619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 34891.9047619 with a remaining 1e-08.
