We're dividing 398239 by 76 
We want to divide 398239 by 76.

On to step 1:
76 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 76

Let's proceed to step 2:
39 divided by 76 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 76

Step 3:
If we divide 398 by 76, we get 5 and a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 380 from 398, we get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 76

On to step 4:
76 can be fit into 182 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 152 from 182 leaves us with 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 76

Moving on to step 5:
When dividing 303 by 76, we get 3 with a remainder of 75.
The next digit of our result is 3. 
Result so far: 523.0
Subtracting 228 from 303 leaves us with 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 76

On to step 6:
76 goes into 759 9 times with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 5239.0
Subtracting 684 from 759 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
750 divided by 76 is 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 5239.9
The remainder is 66 after subtracting 684 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
76 can be fit into 660 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 5239.98
If we subtract 608 from 660, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
The number 76 fits into 520 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5239.986
If we subtract 456 from 520, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
If we divide 640 by 76, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5239.9868
If we take 608 away from 640, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 76, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5239.98684
Deduct 304 from 320 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
160 divided by 76 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 5239.986842
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
If we divide 80 by 76, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 5239.9868421
Subtracting 76 from 80 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.

Step 14:
The number 76 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 5239.9868421
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 5239.9868421 and a remainder of 4e-08.
