We divide 38667990 by 108
We want to figure out the number of times 38667990 can be divided by 108.

Going ahead to step 1:
The number 108 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 108

Moving on to step 2:
108 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 108

Let's proceed to step 3:
If we divide 386 by 108, we get 3 and a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 324 away from 386, we end up with 62.
Take the next digit (6) from the dividend and append it to 62, then repeat: 626 / 108

Going ahead to step 4:
108 can be fit into 626 5 times, resulting in a remainder of 86.
The next digit of our result is 5. 
Result so far: 35.0
If we take 540 away from 626, we end up with 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 108

Advancing to step 5:
If we divide 867 by 108, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 358.0
Subtract 864 from 867 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 108

On to step 6:
39 divided by 108 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 3580.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 108

Step 7:
The number 108 fits into 399 3 times, leaving a remainder of 75.
Write down 3 as next digit of the result. 
Result so far: 35803.0
If we subtract 324 from 399, we get 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 108

Let's proceed to step 8:
When dividing 750 by 108, we get 6 with a remainder of 102.
The next digit of our result is 6. 
Result so far: 358036.0
Subtracting 648 from 750 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
108 can be fit into 1020 9 times, resulting in a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 358036.9
Deduct 972 from 1020 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
If we divide 480 by 108, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 358036.94
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
108 can be fit into 480 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 358036.944
The remainder is 48 after subtracting 432 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 358036.944, with a leftover of 0.0048.
