We're dividing 623284 by 30 
We want to figure out the number of times 623284 can be divided by 30.

On 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.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 30

Moving on to step 2:
30 can be fit into 62 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 60 from 62, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 30

Moving on to step 3:
30 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 23, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 30

On to step 4:
The number 30 fits into 232 7 times, leaving a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Deduct 210 from 232 and we're left with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 30

On to step 5:
30 goes into 228 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 2077.0
Deduct 210 from 228 and we're left with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 30

Step 6:
The number 30 fits into 184 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 20776.0
The remainder is 4 after subtracting 180 from 184.
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 7:
If we divide 40 by 30, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 20776.1
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 20776.13
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.

Going ahead to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 20776.133
Subtracting 90 from 100 leaves us 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.

The final outcome is 20776.133, with a leftover of 0.001.
