40431884 divided by 38 
We want to figure out the number of times 40431884 can be divided by 38.

Step 1:
If we divide 4 by 38, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 38

Step 2:
38 can be fit into 40 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 38 from 40, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 38

Let's proceed to step 3:
24 divided by 38 is 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 24, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 38

On to step 4:
When dividing 243 by 38, we get 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtract 228 from 243 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 38

Let's proceed to step 5:
151 divided by 38 is 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 1063.0
Subtract 114 from 151 to get 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 38

On to step 6:
38 goes into 378 9 times with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 10639.0
Subtract 342 from 378 to get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 38

Going ahead to step 7:
38 can be fit into 368 9 times, resulting in a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 106399.0
If we take 342 away from 368, we end up with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 38

Advancing to step 8:
38 can be fit into 264 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 1063996.0
Subtracting 228 from 264 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
38 goes into 360 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 1063996.9
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
180 divided by 38 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 1063996.94
Subtracting 152 from 180 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
When dividing 280 by 38, we get 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 1063996.947
If we take 266 away from 280, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
38 can be fit into 140 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 1063996.9473
If we subtract 114 from 140, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
When dividing 260 by 38, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1063996.94736
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
If we divide 320 by 38, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 1063996.947368
Deduct 304 from 320 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
If we divide 160 by 38, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1063996.9473684
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 16:
If we divide 80 by 38, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 1063996.94736842
Subtracting 76 from 80 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 1063996.94736842 and a remainder of 4e-09.
