Let's divide 40100409 by 875
Let's see how many times 875 fits into 40100409.

On to step 1:
The number 875 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 875

On to step 2:
When dividing 40 by 875, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 875

On to step 3:
If we divide 401 by 875, we get 0 and a remainder of 401.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 401 leaves us with 401.
Include the next digit (0) from the dividend after 401, then repeat: 4010 / 875

Moving on to step 4:
When dividing 4010 by 875, we get 4 with a remainder of 510.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 3500 away from 4010, we end up with 510.
Fetch the next digit (0) from the dividend, attach it to 510 and continue: 5100 / 875

Let's proceed to step 5:
When dividing 5100 by 875, we get 5 with a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 4375 away from 5100, we end up with 725.
Bring next digit (4) of the dividend behind the 725 and repeat the process: 7254 / 875

On to step 6:
The number 875 fits into 7254 8 times, leaving a remainder of 254.
Put 8 as the next digit of the answer. 
Result so far: 458.0
Deduct 7000 from 7254 and we're left with 254.
Append the next digit (0) from the dividend to 254 and continue with: 2540 / 875

Going ahead to step 7:
If we divide 2540 by 875, we get 2 and a remainder of 790.
Put 2 as the next digit of the answer. 
Result so far: 4582.0
Subtracting 1750 from 2540 leaves us with 790.
Grab the next digit (9) from the dividend, add it to 790, then carry on: 7909 / 875

Let's proceed to step 8:
875 goes into 7909 9 times with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 45829.0
Subtracting 7875 from 7909 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 875, we get 0 and a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 45829.0
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 10:
875 can be fit into 3400 3 times, resulting in a remainder of 775.
The next digit of our result is 3. 
Result so far: 45829.03
If we take 2625 away from 3400, we end up with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 11:
875 goes into 7750 8 times with a remainder of 750.
Put 8 as the next digit of the answer. 
Result so far: 45829.038
If we subtract 7000 from 7750, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 12:
875 can be fit into 7500 8 times, resulting in a remainder of 500.
The next digit of our result is 8. 
Result so far: 45829.0388
If we subtract 7000 from 7500, 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.

The final result is 45829.0388 with a remainder of 0.005.
