Let's divide 30000911 by 878
We're looking to find how many times 878 goes into 30000911.

Advancing to step 1:
878 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 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
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 878

Moving on to step 3:
If we divide 300 by 878, we get 0 and a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 300 to get 300.
Include the next digit (0) from the dividend after 300, then repeat: 3000 / 878

Going ahead to step 4:
878 can be fit into 3000 3 times, resulting in a remainder of 366.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 2634 from 3000, we get 366.
Fetch the next digit (0) from the dividend, attach it to 366 and continue: 3660 / 878

Step 5:
878 can be fit into 3660 4 times, resulting in a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 3512 from 3660, we get 148.
Include the next digit (9) from the dividend after 148, then repeat: 1489 / 878

Going ahead to step 6:
If we divide 1489 by 878, we get 1 and a remainder of 611.
The number 1 becomes the next digit in our result. 
Result so far: 341.0
Subtract 878 from 1489 to get 611.
Grab the next digit (1) from the dividend, add it to 611, then carry on: 6111 / 878

Step 7:
6111 divided by 878 is 6 with a remainder of 843.
Use 6 as the next digit of our solution. 
Result so far: 3416.0
Subtracting 5268 from 6111 leaves us with 843.
Bring next digit (1) of the dividend behind the 843 and repeat the process: 8431 / 878

Moving on to step 8:
When dividing 8431 by 878, we get 9 with a remainder of 529.
Record the quotient 9 as the next digit in the result. 
Result so far: 34169.0
If we subtract 7902 from 8431, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 9:
878 goes into 5290 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 34169.6
Deduct 5268 from 5290 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 878, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 34169.6
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
The number 878 fits into 2200 2 times, leaving a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 34169.602
Subtracting 1756 from 2200 leaves us with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 12:
If we divide 4440 by 878, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 34169.6025
If we take 4390 away from 4440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
878 can be fit into 500 0 times, resulting in a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 34169.6025
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 14:
5000 divided by 878 is 5 with a remainder of 610.
Record the quotient 5 as the next digit in the result. 
Result so far: 34169.602505
If we subtract 4390 from 5000, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 15:
If we divide 6100 by 878, we get 6 and a remainder of 832.
Use 6 as the next digit of our solution. 
Result so far: 34169.6025056
Subtracting 5268 from 6100 leaves us with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 16:
878 can be fit into 8320 9 times, resulting in a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 34169.60250569
Deduct 7902 from 8320 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The quotient of the division is 34169.60250569, and the remainder is 4.18e-07.
