We're dividing 40890256 by 809 
Let's see how many times 809 fits into 40890256.

Let's proceed to step 1:
When dividing 4 by 809, we get 0 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.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 809

Advancing to step 2:
The number 809 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 809

Step 3:
When dividing 408 by 809, we get 0 with a remainder of 408.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 408, we get 408.
Include the next digit (9) from the dividend after 408, then repeat: 4089 / 809

On to step 4:
When dividing 4089 by 809, we get 5 with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4045 from 4089 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 809

Going ahead to step 5:
If we divide 440 by 809, we get 0 and a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 440, we get 440.
Bring next digit (2) of the dividend behind the 440 and repeat the process: 4402 / 809

Let's proceed to step 6:
809 goes into 4402 5 times with a remainder of 357.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Subtract 4045 from 4402 to get 357.
Append the next digit (5) from the dividend to 357 and continue with: 3575 / 809

Step 7:
If we divide 3575 by 809, we get 4 and a remainder of 339.
Record the quotient 4 as the next digit in the result. 
Result so far: 5054.0
Subtract 3236 from 3575 to get 339.
Bring next digit (6) of the dividend behind the 339 and repeat the process: 3396 / 809

Advancing to step 8:
The number 809 fits into 3396 4 times, leaving a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 50544.0
The remainder is 160 after subtracting 3236 from 3396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 9:
1600 divided by 809 is 1 with a remainder of 791.
The number 1 becomes the next digit in our result. 
Result so far: 50544.1
Subtract 809 from 1600 to get 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

On to step 10:
When dividing 7910 by 809, we get 9 with a remainder of 629.
Write down 9 as next digit of the result. 
Result so far: 50544.19
Deduct 7281 from 7910 and we're left with 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Going ahead to step 11:
809 goes into 6290 7 times with a remainder of 627.
The next digit of our result is 7. 
Result so far: 50544.197
Subtracting 5663 from 6290 leaves us with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 12:
If we divide 6270 by 809, we get 7 and a remainder of 607.
Use 7 as the next digit of our solution. 
Result so far: 50544.1977
If we subtract 5663 from 6270, we get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

In conclusion, the division gives 50544.1977 with a balance of 0.00607.
