40409632 ÷ 912 
We want to figure out the number of times 40409632 can be divided by 912.

Advancing to step 1:
If we divide 4 by 912, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 912

Step 2:
912 can be fit into 40 0 times, resulting in 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.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 912

Going ahead to step 3:
If we divide 404 by 912, we get 0 and a remainder of 404.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 404, we get 404.
Grab the next digit (0) from the dividend, add it to 404, then carry on: 4040 / 912

Let's proceed to step 4:
4040 divided by 912 is 4 with a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 3648 from 4040 leaves us with 392.
Append the next digit (9) from the dividend to 392 and continue with: 3929 / 912

Going ahead to step 5:
If we divide 3929 by 912, we get 4 and a remainder of 281.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 3648 from 3929, we get 281.
Fetch the next digit (6) from the dividend, attach it to 281 and continue: 2816 / 912

On to step 6:
2816 divided by 912 is 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
Deduct 2736 from 2816 and we're left with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 912

On to step 7:
912 can be fit into 803 0 times, resulting in a remainder of 803.
Use 0 as the next digit of our solution. 
Result so far: 4430.0
Subtracting 0 from 803 leaves us with 803.
Take the next digit (2) from the dividend and append it to 803, then repeat: 8032 / 912

Let's proceed to step 8:
912 can be fit into 8032 8 times, resulting in a remainder of 736.
Write down 8 as next digit of the result. 
Result so far: 44308.0
Deduct 7296 from 8032 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 9:
If we divide 7360 by 912, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 44308.8
If we take 7296 away from 7360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
When dividing 640 by 912, we get 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 44308.8
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 11:
912 can be fit into 6400 7 times, resulting in a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 44308.807
The remainder is 16 after subtracting 6384 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 912, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 44308.807
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
912 can be fit into 1600 1 times, resulting in a remainder of 688.
Use 1 as the next digit of our solution. 
Result so far: 44308.80701
If we subtract 912 from 1600, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 14:
6880 divided by 912 is 7 with a remainder of 496.
Record the quotient 7 as the next digit in the result. 
Result so far: 44308.807017
If we subtract 6384 from 6880, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
4960 divided by 912 is 5 with a remainder of 400.
The next digit of our result is 5. 
Result so far: 44308.8070175
Deduct 4560 from 4960 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
912 can be fit into 4000 4 times, resulting in a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 44308.80701754
If we take 3648 away from 4000, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The final result is 44308.80701754 with a remainder of 3.52e-07.
