We're dividing 40002591 by 881 
Let's see how many times 881 fits into 40002591.

Step 1:
881 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 881

Moving on to step 2:
The number 881 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 881

Let's proceed to step 3:
881 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 400 and we're left with 400.
Take the next digit (0) from the dividend and append it to 400, then repeat: 4000 / 881

On to step 4:
The number 881 fits into 4000 4 times, leaving a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3524 from 4000 and we're left with 476.
Include the next digit (2) from the dividend after 476, then repeat: 4762 / 881

Step 5:
881 can be fit into 4762 5 times, resulting in a remainder of 357.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 4405 away from 4762, we end up with 357.
Fetch the next digit (5) from the dividend, attach it to 357 and continue: 3575 / 881

Moving on to step 6:
When dividing 3575 by 881, we get 4 with a remainder of 51.
The next digit of our result is 4. 
Result so far: 454.0
If we subtract 3524 from 3575, we get 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 881

Going ahead to step 7:
The number 881 fits into 519 0 times, leaving a remainder of 519.
Record the quotient 0 as the next digit in the result. 
Result so far: 4540.0
If we subtract 0 from 519, we get 519.
Append the next digit (1) from the dividend to 519 and continue with: 5191 / 881

Moving on to step 8:
5191 divided by 881 is 5 with a remainder of 786.
The next digit of our result is 5. 
Result so far: 45405.0
If we take 4405 away from 5191, we end up with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Let's proceed to step 9:
881 goes into 7860 8 times with a remainder of 812.
Use 8 as the next digit of our solution. 
Result so far: 45405.8
Subtract 7048 from 7860 to get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Going ahead to step 10:
If we divide 8120 by 881, we get 9 and a remainder of 191.
Put 9 as the next digit of the answer. 
Result so far: 45405.89
If we take 7929 away from 8120, we end up with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 11:
If we divide 1910 by 881, we get 2 and a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 45405.892
Subtracting 1762 from 1910 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 12:
881 goes into 1480 1 times with a remainder of 599.
Write down 1 as next digit of the result. 
Result so far: 45405.8921
Deduct 881 from 1480 and we're left with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 13:
881 goes into 5990 6 times with a remainder of 704.
Write down 6 as next digit of the result. 
Result so far: 45405.89216
If we take 5286 away from 5990, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 14:
When dividing 7040 by 881, we get 7 with a remainder of 873.
Put 7 as the next digit of the answer. 
Result so far: 45405.892167
The remainder is 873 after subtracting 6167 from 7040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8730, and continue the process.

On to step 15:
If we divide 8730 by 881, we get 9 and a remainder of 801.
Record the quotient 9 as the next digit in the result. 
Result so far: 45405.8921679
If we take 7929 away from 8730, we end up with 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Going ahead to step 16:
881 goes into 8010 9 times with a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 45405.89216799
Subtract 7929 from 8010 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 45405.89216799 with a remaining 8.1e-08.
