We're dividing 23378986 by 878 
Let's see how many times 878 fits into 23378986.

Moving on to step 1:
The number 878 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 878

Let's proceed to step 2:
The number 878 fits into 23 0 times, leaving a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 878

Going ahead to step 3:
233 divided by 878 is 0 with a remainder of 233.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 233, we end up with 233.
Include the next digit (7) from the dividend after 233, then repeat: 2337 / 878

Going ahead to step 4:
2337 divided by 878 is 2 with a remainder of 581.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1756 from 2337 leaves us with 581.
Take the next digit (8) from the dividend and append it to 581, then repeat: 5818 / 878

Advancing to step 5:
The number 878 fits into 5818 6 times, leaving a remainder of 550.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 550 after subtracting 5268 from 5818.
Bring next digit (9) of the dividend behind the 550 and repeat the process: 5509 / 878

Let's proceed to step 6:
If we divide 5509 by 878, we get 6 and a remainder of 241.
The next digit of our result is 6. 
Result so far: 266.0
Subtracting 5268 from 5509 leaves us with 241.
Bring next digit (8) of the dividend behind the 241 and repeat the process: 2418 / 878

Let's proceed to step 7:
878 can be fit into 2418 2 times, resulting in a remainder of 662.
The number 2 becomes the next digit in our result. 
Result so far: 2662.0
Subtract 1756 from 2418 to get 662.
Grab the next digit (6) from the dividend, add it to 662, then carry on: 6626 / 878

Going ahead to step 8:
878 goes into 6626 7 times with a remainder of 480.
Record the quotient 7 as the next digit in the result. 
Result so far: 26627.0
The remainder is 480 after subtracting 6146 from 6626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 9:
When dividing 4800 by 878, we get 5 with a remainder of 410.
The next digit of our result is 5. 
Result so far: 26627.5
Subtracting 4390 from 4800 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
4100 divided by 878 is 4 with a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 26627.54
Subtract 3512 from 4100 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

On to step 11:
If we divide 5880 by 878, we get 6 and a remainder of 612.
Use 6 as the next digit of our solution. 
Result so far: 26627.546
Subtracting 5268 from 5880 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 12:
The number 878 fits into 6120 6 times, leaving a remainder of 852.
The number 6 becomes the next digit in our result. 
Result so far: 26627.5466
Subtracting 5268 from 6120 leaves us with 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

After the division, we end up with 26627.5466 and a remainder of 0.00852.
