We're dividing 4090391 by 881 
We're looking to find how many times 881 goes into 4090391.

On to step 1:
881 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 881

Going ahead to step 2:
881 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 881

Moving on to step 3:
881 can be fit into 409 0 times, resulting in a remainder of 409.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 409 after subtracting 0 from 409.
Include the next digit (0) from the dividend after 409, then repeat: 4090 / 881

Advancing to step 4:
When dividing 4090 by 881, we get 4 with a remainder of 566.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3524 from 4090 and we're left with 566.
Append the next digit (3) from the dividend to 566 and continue with: 5663 / 881

Moving on to step 5:
The number 881 fits into 5663 6 times, leaving a remainder of 377.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 5286 from 5663 leaves us with 377.
Append the next digit (9) from the dividend to 377 and continue with: 3779 / 881

Going ahead to step 6:
881 goes into 3779 4 times with a remainder of 255.
Put 4 as the next digit of the answer. 
Result so far: 464.0
If we take 3524 away from 3779, we end up with 255.
Grab the next digit (1) from the dividend, add it to 255, then carry on: 2551 / 881

Advancing to step 7:
The number 881 fits into 2551 2 times, leaving a remainder of 789.
The next digit of our result is 2. 
Result so far: 4642.0
Deduct 1762 from 2551 and we're left with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Moving on to step 8:
When dividing 7890 by 881, we get 8 with a remainder of 842.
The number 8 becomes the next digit in our result. 
Result so far: 4642.8
The remainder is 842 after subtracting 7048 from 7890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Going ahead to step 9:
8420 divided by 881 is 9 with a remainder of 491.
The next digit of our result is 9. 
Result so far: 4642.89
Subtract 7929 from 8420 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 10:
881 can be fit into 4910 5 times, resulting in a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 4642.895
If we subtract 4405 from 4910, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 11:
When dividing 5050 by 881, we get 5 with a remainder of 645.
Use 5 as the next digit of our solution. 
Result so far: 4642.8955
If we take 4405 away from 5050, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

The quotient of the division is 4642.8955, and the remainder is 0.00645.
