We divide 651680 by 30
We want to figure out the number of times 651680 can be divided by 30.

Let's proceed to step 1:
6 divided by 30 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 30

Step 2:
30 can be fit into 65 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 60 from 65.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 30

Let's proceed to step 3:
If we divide 51 by 30, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 30 from 51 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 30

Moving on to step 4:
If we divide 216 by 30, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
The remainder is 6 after subtracting 210 from 216.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 30

Advancing to step 5:
The number 30 fits into 68 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2172.0
If we take 60 away from 68, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 30

Step 6:
30 goes into 80 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 21722.0
Deduct 60 from 80 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 30 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 21722.6
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 21722.66
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 21722.66, with a leftover of 0.02.
