We look at the division of 40857903 by 9 
We want to figure out the number of times 40857903 can be divided by 9.

Moving on to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 9

Moving on to step 2:
When dividing 40 by 9, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 36 from 40, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 9

Advancing to step 3:
When dividing 48 by 9, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 3 after subtracting 45 from 48.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Advancing to step 4:
If we divide 35 by 9, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 453.0
Subtracting 27 from 35 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 9

Moving on to step 5:
The number 9 fits into 87 9 times, leaving a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 4539.0
If we take 81 away from 87, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

Let's proceed to step 6:
9 can be fit into 69 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 45397.0
Subtracting 63 from 69 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 9

Advancing to step 7:
9 goes into 60 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 453976.0
The remainder is 6 after subtracting 54 from 60.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 9

Advancing to step 8:
If we divide 63 by 9, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 4539767.0
The remainder is 0 after subtracting 63 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4539767.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 9, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4539767.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 4539767.0, and the remainder is 0.0.
