We're dividing 39240387 by 108 
Our goal is to divide 39240387 by 108.

Moving on to step 1:
When dividing 3 by 108, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 108

Going ahead to step 2:
When dividing 39 by 108, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 108

Let's proceed to step 3:
108 can be fit into 392 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 324 from 392 leaves us with 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 108

Step 4:
108 can be fit into 684 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 648 away from 684, we end up with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 108

Moving on to step 5:
When dividing 360 by 108, we get 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 363.0
If we subtract 324 from 360, we get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 108

Moving on to step 6:
363 divided by 108 is 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 3633.0
If we subtract 324 from 363, we get 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 108

On to step 7:
108 can be fit into 398 3 times, resulting in a remainder of 74.
The next digit of our result is 3. 
Result so far: 36333.0
Deduct 324 from 398 and we're left with 74.
Take the next digit (7) from the dividend and append it to 74, then repeat: 747 / 108

Step 8:
747 divided by 108 is 6 with a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 363336.0
Subtract 648 from 747 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
990 divided by 108 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 363336.9
The remainder is 18 after subtracting 972 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 108, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 363336.91
If we take 108 away from 180, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
The number 108 fits into 720 6 times, leaving a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 363336.916
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
108 can be fit into 720 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 363336.9166
Subtracting 648 from 720 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 363336.9166, with a leftover of 0.00072.
