We look at the division of 30790781 by 878 
We want to divide 30790781 by 878.

On to step 1:
878 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 878

On to step 2:
When dividing 30 by 878, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 878

Going ahead to step 3:
If we divide 307 by 878, we get 0 and a remainder of 307.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 307 after subtracting 0 from 307.
Take the next digit (9) from the dividend and append it to 307, then repeat: 3079 / 878

Moving on to step 4:
878 can be fit into 3079 3 times, resulting in a remainder of 445.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2634 from 3079, we get 445.
Append the next digit (0) from the dividend to 445 and continue with: 4450 / 878

Let's proceed to step 5:
878 goes into 4450 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 4390 from 4450 leaves us with 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 878

Going ahead to step 6:
If we divide 607 by 878, we get 0 and a remainder of 607.
Put 0 as the next digit of the answer. 
Result so far: 350.0
Subtract 0 from 607 to get 607.
Fetch the next digit (8) from the dividend, attach it to 607 and continue: 6078 / 878

Going ahead to step 7:
6078 divided by 878 is 6 with a remainder of 810.
The next digit of our result is 6. 
Result so far: 3506.0
Subtracting 5268 from 6078 leaves us with 810.
Take the next digit (1) from the dividend and append it to 810, then repeat: 8101 / 878

On to step 8:
If we divide 8101 by 878, we get 9 and a remainder of 199.
The next digit of our result is 9. 
Result so far: 35069.0
The remainder is 199 after subtracting 7902 from 8101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 9:
1990 divided by 878 is 2 with a remainder of 234.
Use 2 as the next digit of our solution. 
Result so far: 35069.2
If we take 1756 away from 1990, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 10:
When dividing 2340 by 878, we get 2 with a remainder of 584.
The next digit of our result is 2. 
Result so far: 35069.22
Subtract 1756 from 2340 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

After the division, we end up with 35069.22 and a remainder of 0.584.
