We're dividing 309603 by 38 
We want to divide 309603 by 38.

Advancing to step 1:
38 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 38

Advancing to step 2:
38 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 38

Step 3:
38 can be fit into 309 8 times, resulting in a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 304 from 309 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 38

Going ahead to step 4:
38 can be fit into 56 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we subtract 38 from 56, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 38

Advancing to step 5:
When dividing 180 by 38, we get 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 814.0
Subtracting 152 from 180 leaves us with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 38

Let's proceed to step 6:
38 can be fit into 283 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 8147.0
If we take 266 away from 283, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
When dividing 170 by 38, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 8147.4
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
The number 38 fits into 180 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 8147.44
If we subtract 152 from 180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 8147.44 with a remaining 0.028.
