40073909 ÷ 38 
Let's see how many times 38 fits into 40073909.

Advancing to step 1:
The number 38 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 38

Step 2:
When dividing 40 by 38, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 38 from 40 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 38

Advancing to step 3:
20 divided by 38 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 38

Advancing to step 4:
38 can be fit into 207 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtract 190 from 207 to get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 38

Moving on to step 5:
When dividing 173 by 38, we get 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 1054.0
If we take 152 away from 173, we end up with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 38

Advancing to step 6:
If we divide 219 by 38, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 10545.0
Deduct 190 from 219 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 38

Going ahead to step 7:
290 divided by 38 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 105457.0
Deduct 266 from 290 and we're left with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 38

Advancing to step 8:
If we divide 249 by 38, we get 6 and a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 1054576.0
If we take 228 away from 249, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
210 divided by 38 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1054576.5
If we take 190 away from 210, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
38 goes into 200 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 1054576.55
If we take 190 away from 200, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1054576.55, and the remainder is 0.01.
