Let's divide 658350 by 21
Let's see how many times 21 fits into 658350.

Advancing to step 1:
The number 21 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 21

Going ahead to step 2:
If we divide 65 by 21, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 2 after subtracting 63 from 65.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 21

Advancing to step 3:
21 can be fit into 28 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 21 away from 28, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 21

On to step 4:
The number 21 fits into 73 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Subtract 63 from 73 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 21

Going ahead to step 5:
The number 21 fits into 105 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3135.0
If we take 105 away from 105, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 21

Step 6:
The number 21 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 31350.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
When dividing 0 by 21, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31350.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 21, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31350.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 31350.0 with a remaining 0.0.
