40567970 ÷ 915 
We want to divide 40567970 by 915.

Step 1:
When dividing 4 by 915, we get 0 with 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.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 915

On to step 2:
If we divide 40 by 915, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 915

Going ahead to step 3:
When dividing 405 by 915, we get 0 with a remainder of 405.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 405 and we're left with 405.
Grab the next digit (6) from the dividend, add it to 405, then carry on: 4056 / 915

Let's proceed to step 4:
The number 915 fits into 4056 4 times, leaving a remainder of 396.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3660 from 4056 to get 396.
Take the next digit (7) from the dividend and append it to 396, then repeat: 3967 / 915

Step 5:
3967 divided by 915 is 4 with a remainder of 307.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we take 3660 away from 3967, we end up with 307.
Bring next digit (9) of the dividend behind the 307 and repeat the process: 3079 / 915

Going ahead to step 6:
If we divide 3079 by 915, we get 3 and a remainder of 334.
The next digit of our result is 3. 
Result so far: 443.0
If we subtract 2745 from 3079, we get 334.
Fetch the next digit (7) from the dividend, attach it to 334 and continue: 3347 / 915

Step 7:
3347 divided by 915 is 3 with a remainder of 602.
Put 3 as the next digit of the answer. 
Result so far: 4433.0
If we subtract 2745 from 3347, we get 602.
Bring next digit (0) of the dividend behind the 602 and repeat the process: 6020 / 915

Advancing to step 8:
915 can be fit into 6020 6 times, resulting in a remainder of 530.
Write down 6 as next digit of the result. 
Result so far: 44336.0
The remainder is 530 after subtracting 5490 from 6020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 9:
915 can be fit into 5300 5 times, resulting in a remainder of 725.
Record the quotient 5 as the next digit in the result. 
Result so far: 44336.5
Subtract 4575 from 5300 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 10:
915 goes into 7250 7 times with a remainder of 845.
Record the quotient 7 as the next digit in the result. 
Result so far: 44336.57
If we take 6405 away from 7250, we end up with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Advancing to step 11:
The number 915 fits into 8450 9 times, leaving a remainder of 215.
The number 9 becomes the next digit in our result. 
Result so far: 44336.579
Subtract 8235 from 8450 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 12:
915 can be fit into 2150 2 times, resulting in a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 44336.5792
Subtract 1830 from 2150 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
The number 915 fits into 3200 3 times, leaving a remainder of 455.
The next digit of our result is 3. 
Result so far: 44336.57923
Subtracting 2745 from 3200 leaves us with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 14:
When dividing 4550 by 915, we get 4 with a remainder of 890.
Use 4 as the next digit of our solution. 
Result so far: 44336.579234
Subtracting 3660 from 4550 leaves us with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Advancing to step 15:
When dividing 8900 by 915, we get 9 with a remainder of 665.
Write down 9 as next digit of the result. 
Result so far: 44336.5792349
Subtract 8235 from 8900 to get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Let's proceed to step 16:
915 goes into 6650 7 times with a remainder of 245.
Write down 7 as next digit of the result. 
Result so far: 44336.57923497
Subtracting 6405 from 6650 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

After the division, we end up with 44336.57923497 and a remainder of 2.45e-07.
