We're dividing 40890453 by 507 
Our goal is to divide 40890453 by 507.

Moving on to step 1:
When dividing 4 by 507, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 507

Let's proceed to step 2:
The number 507 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 507

Moving on to step 3:
408 divided by 507 is 0 with a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 408 and we're left with 408.
Bring next digit (9) of the dividend behind the 408 and repeat the process: 4089 / 507

Moving on to step 4:
The number 507 fits into 4089 8 times, leaving a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 4056 from 4089 to get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 507

Step 5:
330 divided by 507 is 0 with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Deduct 0 from 330 and we're left with 330.
Grab the next digit (4) from the dividend, add it to 330, then carry on: 3304 / 507

On to step 6:
507 can be fit into 3304 6 times, resulting in a remainder of 262.
The number 6 becomes the next digit in our result. 
Result so far: 806.0
Subtract 3042 from 3304 to get 262.
Take the next digit (5) from the dividend and append it to 262, then repeat: 2625 / 507

On to step 7:
The number 507 fits into 2625 5 times, leaving a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 8065.0
The remainder is 90 after subtracting 2535 from 2625.
Include the next digit (3) from the dividend after 90, then repeat: 903 / 507

Advancing to step 8:
If we divide 903 by 507, we get 1 and a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 80651.0
Subtract 507 from 903 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 9:
When dividing 3960 by 507, we get 7 with a remainder of 411.
The number 7 becomes the next digit in our result. 
Result so far: 80651.7
Subtracting 3549 from 3960 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 10:
507 can be fit into 4110 8 times, resulting in a remainder of 54.
The next digit of our result is 8. 
Result so far: 80651.78
Subtract 4056 from 4110 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
When dividing 540 by 507, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 80651.781
If we subtract 507 from 540, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
507 can be fit into 330 0 times, resulting in a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 80651.781
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 13:
507 goes into 3300 6 times with a remainder of 258.
Write down 6 as next digit of the result. 
Result so far: 80651.78106
If we subtract 3042 from 3300, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 14:
The number 507 fits into 2580 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 80651.781065
The remainder is 45 after subtracting 2535 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 15:
If we divide 450 by 507, we get 0 and a remainder of 450.
The next digit of our result is 0. 
Result so far: 80651.781065
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 16:
The number 507 fits into 4500 8 times, leaving a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 80651.78106508
If we subtract 4056 from 4500, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

The quotient of the division is 80651.78106508, and the remainder is 4.44e-07.
