39866592 ÷ 38 
We want to figure out the number of times 39866592 can be divided by 38.

On to step 1:
38 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 38

On to step 2:
38 goes into 39 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 38 from 39.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 38

Step 3:
18 divided by 38 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 18, we get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 38

On to step 4:
If we divide 186 by 38, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 152 away from 186, we end up with 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 38

Let's proceed to step 5:
38 goes into 346 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 1049.0
Deduct 342 from 346 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 38

Going ahead to step 6:
38 goes into 45 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 10491.0
If we subtract 38 from 45, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 38

Let's proceed to step 7:
The number 38 fits into 79 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 104912.0
If we take 76 away from 79, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 38

On to step 8:
If we divide 32 by 38, we get 0 and a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 1049120.0
Subtract 0 from 32 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1049120.8
If we subtract 304 from 320, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 38 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1049120.84
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
38 goes into 80 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1049120.842
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 38 fits into 40 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1049120.8421
Subtracting 38 from 40 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 38, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1049120.8421
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
The number 38 fits into 200 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1049120.842105
Deduct 190 from 200 and we're left 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.

Going ahead to step 15:
100 divided by 38 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1049120.8421052
Subtracting 76 from 100 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
240 divided by 38 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1049120.84210526
Deduct 228 from 240 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 1049120.84210526, and the remainder is 1.2e-08.
