We're dividing 38434231 by 8 
We're looking to find how many times 8 goes into 38434231.

Step 1:
If we divide 3 by 8, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 8

Going ahead to step 2:
8 can be fit into 38 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 32 from 38 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 8

Let's proceed to step 3:
64 divided by 8 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 64 from 64 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 8

Going ahead to step 4:
The number 8 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 8

Advancing to step 5:
34 divided by 8 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4804.0
Subtract 32 from 34 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 8

On to step 6:
8 goes into 22 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 48042.0
Deduct 16 from 22 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 8

Let's proceed to step 7:
8 can be fit into 63 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 480427.0
The remainder is 7 after subtracting 56 from 63.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 8

On to step 8:
8 can be fit into 71 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 4804278.0
Subtract 64 from 71 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 8, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 4804278.8
Subtract 64 from 70 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
8 can be fit into 60 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 4804278.87
Subtracting 56 from 60 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.

Moving on to step 11:
The number 8 fits into 40 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4804278.875
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4804278.875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4804278.875
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4804278.875 and a remainder of 0.0.
