Let's divide 30124020 by 817
We want to figure out the number of times 30124020 can be divided by 817.

Moving on to step 1:
817 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 817

Let's proceed to step 2:
If we divide 30 by 817, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 817

On to step 3:
817 goes into 301 0 times with a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 301, we get 301.
Append the next digit (2) from the dividend to 301 and continue with: 3012 / 817

On to step 4:
If we divide 3012 by 817, we get 3 and a remainder of 561.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2451 away from 3012, we end up with 561.
Grab the next digit (4) from the dividend, add it to 561, then carry on: 5614 / 817

On to step 5:
When dividing 5614 by 817, we get 6 with a remainder of 712.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 712 after subtracting 4902 from 5614.
Append the next digit (0) from the dividend to 712 and continue with: 7120 / 817

Going ahead to step 6:
817 can be fit into 7120 8 times, resulting in a remainder of 584.
The next digit of our result is 8. 
Result so far: 368.0
Subtract 6536 from 7120 to get 584.
Include the next digit (2) from the dividend after 584, then repeat: 5842 / 817

Moving on to step 7:
The number 817 fits into 5842 7 times, leaving a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 3687.0
If we take 5719 away from 5842, we end up with 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 817

Moving on to step 8:
817 goes into 1230 1 times with a remainder of 413.
Write down 1 as next digit of the result. 
Result so far: 36871.0
If we take 817 away from 1230, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 9:
817 can be fit into 4130 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 36871.5
The remainder is 45 after subtracting 4085 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
817 can be fit into 450 0 times, resulting in a remainder of 450.
The next digit of our result is 0. 
Result so far: 36871.5
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 11:
If we divide 4500 by 817, we get 5 and a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 36871.505
Deduct 4085 from 4500 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 12:
If we divide 4150 by 817, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 36871.5055
If we take 4085 away from 4150, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 36871.5055 with a remainder of 0.00065.
