We look at the division of 40809269 by 878 
We want to figure out the number of times 40809269 can be divided by 878.

Advancing to step 1:
When dividing 4 by 878, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 878

Step 2:
878 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 878

On to step 3:
408 divided by 878 is 0 with a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 408 leaves us with 408.
Take the next digit (0) from the dividend and append it to 408, then repeat: 4080 / 878

Step 4:
If we divide 4080 by 878, we get 4 and a remainder of 568.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 568 after subtracting 3512 from 4080.
Bring next digit (9) of the dividend behind the 568 and repeat the process: 5689 / 878

Going ahead to step 5:
878 goes into 5689 6 times with a remainder of 421.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 5268 away from 5689, we end up with 421.
Append the next digit (2) from the dividend to 421 and continue with: 4212 / 878

Let's proceed to step 6:
878 goes into 4212 4 times with a remainder of 700.
Write down 4 as next digit of the result. 
Result so far: 464.0
Subtract 3512 from 4212 to get 700.
Bring next digit (6) of the dividend behind the 700 and repeat the process: 7006 / 878

Going ahead to step 7:
The number 878 fits into 7006 7 times, leaving a remainder of 860.
Record the quotient 7 as the next digit in the result. 
Result so far: 4647.0
If we subtract 6146 from 7006, we get 860.
Grab the next digit (9) from the dividend, add it to 860, then carry on: 8609 / 878

Let's proceed to step 8:
878 goes into 8609 9 times with a remainder of 707.
Write down 9 as next digit of the result. 
Result so far: 46479.0
Subtracting 7902 from 8609 leaves us with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Let's proceed to step 9:
878 goes into 7070 8 times with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 46479.8
If we take 7024 away from 7070, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
878 goes into 460 0 times with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 46479.8
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
When dividing 4600 by 878, we get 5 with a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 46479.805
If we subtract 4390 from 4600, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
2100 divided by 878 is 2 with a remainder of 344.
Use 2 as the next digit of our solution. 
Result so far: 46479.8052
If we subtract 1756 from 2100, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 13:
The number 878 fits into 3440 3 times, leaving a remainder of 806.
The next digit of our result is 3. 
Result so far: 46479.80523
The remainder is 806 after subtracting 2634 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

On to step 14:
8060 divided by 878 is 9 with a remainder of 158.
Write down 9 as next digit of the result. 
Result so far: 46479.805239
Subtracting 7902 from 8060 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 15:
878 goes into 1580 1 times with a remainder of 702.
Use 1 as the next digit of our solution. 
Result so far: 46479.8052391
Subtracting 878 from 1580 leaves us with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Moving on to step 16:
878 can be fit into 7020 7 times, resulting in a remainder of 874.
Use 7 as the next digit of our solution. 
Result so far: 46479.80523917
If we take 6146 away from 7020, we end up with 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

The final outcome is 46479.80523917, with a leftover of 8.74e-07.
