216643 divided by 30 
We want to figure out the number of times 216643 can be divided by 30.

Advancing to step 1:
2 divided by 30 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 30

Moving on to step 2:
30 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 30

Let's proceed to step 3:
30 can be fit into 216 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 210 from 216 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 30

Going ahead to step 4:
30 goes into 66 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 72.0
If we take 60 away from 66, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 30

On to step 5:
When dividing 64 by 30, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 722.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 30

Advancing to step 6:
The number 30 fits into 43 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 7221.0
The remainder is 13 after subtracting 30 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 30, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 7221.4
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 7221.43
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 7221.433
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 7221.433 and a remainder of 0.001.
