We look at the division of 40155496 by 915 
We want to figure out the number of times 40155496 can be divided by 915.

Step 1:
915 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 915

Advancing to step 2:
The number 915 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 915

Let's proceed to step 3:
If we divide 401 by 915, we get 0 and a remainder of 401.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 401 after subtracting 0 from 401.
Include the next digit (5) from the dividend after 401, then repeat: 4015 / 915

Step 4:
The number 915 fits into 4015 4 times, leaving a remainder of 355.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3660 from 4015 to get 355.
Bring next digit (5) of the dividend behind the 355 and repeat the process: 3555 / 915

Going ahead to step 5:
915 goes into 3555 3 times with a remainder of 810.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 2745 from 3555 leaves us with 810.
Fetch the next digit (4) from the dividend, attach it to 810 and continue: 8104 / 915

On to step 6:
If we divide 8104 by 915, we get 8 and a remainder of 784.
The next digit of our result is 8. 
Result so far: 438.0
Deduct 7320 from 8104 and we're left with 784.
Fetch the next digit (9) from the dividend, attach it to 784 and continue: 7849 / 915

Going ahead to step 7:
If we divide 7849 by 915, we get 8 and a remainder of 529.
The number 8 becomes the next digit in our result. 
Result so far: 4388.0
Subtracting 7320 from 7849 leaves us with 529.
Fetch the next digit (6) from the dividend, attach it to 529 and continue: 5296 / 915

Let's proceed to step 8:
If we divide 5296 by 915, we get 5 and a remainder of 721.
Write down 5 as next digit of the result. 
Result so far: 43885.0
If we take 4575 away from 5296, we end up with 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Advancing to step 9:
915 goes into 7210 7 times with a remainder of 805.
Record the quotient 7 as the next digit in the result. 
Result so far: 43885.7
Subtract 6405 from 7210 to get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Moving on to step 10:
If we divide 8050 by 915, we get 8 and a remainder of 730.
Use 8 as the next digit of our solution. 
Result so far: 43885.78
Deduct 7320 from 8050 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 11:
If we divide 7300 by 915, we get 7 and a remainder of 895.
Use 7 as the next digit of our solution. 
Result so far: 43885.787
Deduct 6405 from 7300 and we're left with 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8950, and continue the process.

Advancing to step 12:
The number 915 fits into 8950 9 times, leaving a remainder of 715.
Put 9 as the next digit of the answer. 
Result so far: 43885.7879
Subtracting 8235 from 8950 leaves us with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Moving on to step 13:
915 goes into 7150 7 times with a remainder of 745.
Put 7 as the next digit of the answer. 
Result so far: 43885.78797
Subtracting 6405 from 7150 leaves us with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

On to step 14:
7450 divided by 915 is 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 43885.787978
If we subtract 7320 from 7450, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 15:
When dividing 1300 by 915, we get 1 with a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 43885.7879781
If we subtract 915 from 1300, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 16:
If we divide 3850 by 915, we get 4 and a remainder of 190.
Record the quotient 4 as the next digit in the result. 
Result so far: 43885.78797814
Subtract 3660 from 3850 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

After the division, we end up with 43885.78797814 and a remainder of 1.9e-07.
