21558846 divided by 30 
We want to figure out the number of times 21558846 can be divided by 30.

On to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 30

Step 2:
When dividing 21 by 30, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 30

On to step 3:
30 can be fit into 215 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 210 from 215, we get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 30

On to step 4:
30 goes into 55 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 25 after subtracting 30 from 55.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 30

Let's proceed to step 5:
258 divided by 30 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 718.0
Subtracting 240 from 258 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 30

On to step 6:
The number 30 fits into 188 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 7186.0
Deduct 180 from 188 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 30

Moving on to step 7:
30 goes into 84 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 71862.0
Subtract 60 from 84 to get 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 30

Step 8:
246 divided by 30 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 718628.0
Deduct 240 from 246 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.

Let's proceed to step 9:
If we divide 60 by 30, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 718628.2
Subtracting 60 from 60 leaves us 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 10:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 718628.2
Deduct 0 from 0 and we're left 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.

Let's proceed to step 11:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 718628.2
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 718628.2, and the remainder is 0.0.
