30980368 divided by 817 
We want to figure out the number of times 30980368 can be divided by 817.

Advancing to step 1:
3 divided by 817 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 817

On to step 2:
When dividing 30 by 817, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 817

Going ahead to step 3:
If we divide 309 by 817, we get 0 and a remainder of 309.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 309 and we're left with 309.
Include the next digit (8) from the dividend after 309, then repeat: 3098 / 817

On to step 4:
When dividing 3098 by 817, we get 3 with a remainder of 647.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 647 after subtracting 2451 from 3098.
Take the next digit (0) from the dividend and append it to 647, then repeat: 6470 / 817

Moving on to step 5:
817 goes into 6470 7 times with a remainder of 751.
The next digit of our result is 7. 
Result so far: 37.0
If we take 5719 away from 6470, we end up with 751.
Bring next digit (3) of the dividend behind the 751 and repeat the process: 7513 / 817

Going ahead to step 6:
817 goes into 7513 9 times with a remainder of 160.
The number 9 becomes the next digit in our result. 
Result so far: 379.0
The remainder is 160 after subtracting 7353 from 7513.
Append the next digit (6) from the dividend to 160 and continue with: 1606 / 817

Moving on to step 7:
If we divide 1606 by 817, we get 1 and a remainder of 789.
The number 1 becomes the next digit in our result. 
Result so far: 3791.0
If we subtract 817 from 1606, we get 789.
Grab the next digit (8) from the dividend, add it to 789, then carry on: 7898 / 817

Going ahead to step 8:
817 can be fit into 7898 9 times, resulting in a remainder of 545.
The number 9 becomes the next digit in our result. 
Result so far: 37919.0
If we subtract 7353 from 7898, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Moving on to step 9:
The number 817 fits into 5450 6 times, leaving a remainder of 548.
Put 6 as the next digit of the answer. 
Result so far: 37919.6
If we subtract 4902 from 5450, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 10:
817 goes into 5480 6 times with a remainder of 578.
Put 6 as the next digit of the answer. 
Result so far: 37919.66
If we take 4902 away from 5480, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

In conclusion, the division gives 37919.66 with a balance of 0.578.
