40910317 divided by 902 
We want to figure out the number of times 40910317 can be divided by 902.

Step 1:
The number 902 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
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 / 902

Advancing to step 2:
902 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 902

Step 3:
902 can be fit into 409 0 times, resulting in a remainder of 409.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 409 to get 409.
Include the next digit (1) from the dividend after 409, then repeat: 4091 / 902

Let's proceed to step 4:
902 goes into 4091 4 times with a remainder of 483.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 3608 from 4091, we get 483.
Include the next digit (0) from the dividend after 483, then repeat: 4830 / 902

Moving on to step 5:
902 goes into 4830 5 times with a remainder of 320.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 4510 away from 4830, we end up with 320.
Bring next digit (3) of the dividend behind the 320 and repeat the process: 3203 / 902

On to step 6:
3203 divided by 902 is 3 with a remainder of 497.
Write down 3 as next digit of the result. 
Result so far: 453.0
If we subtract 2706 from 3203, we get 497.
Fetch the next digit (1) from the dividend, attach it to 497 and continue: 4971 / 902

Moving on to step 7:
4971 divided by 902 is 5 with a remainder of 461.
The next digit of our result is 5. 
Result so far: 4535.0
Deduct 4510 from 4971 and we're left with 461.
Include the next digit (7) from the dividend after 461, then repeat: 4617 / 902

Going ahead to step 8:
4617 divided by 902 is 5 with a remainder of 107.
Write down 5 as next digit of the result. 
Result so far: 45355.0
Subtracting 4510 from 4617 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 9:
The number 902 fits into 1070 1 times, leaving a remainder of 168.
Write down 1 as next digit of the result. 
Result so far: 45355.1
Deduct 902 from 1070 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 10:
When dividing 1680 by 902, we get 1 with a remainder of 778.
Use 1 as the next digit of our solution. 
Result so far: 45355.11
Subtracting 902 from 1680 leaves us with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

After the division, we end up with 45355.11 and a remainder of 0.778.
