3879198 ÷ 304 
Let's see how many times 304 fits into 3879198.

Moving on to step 1:
If we divide 3 by 304, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 304

On to step 2:
If we divide 38 by 304, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 304

Going ahead to step 3:
387 divided by 304 is 1 with a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 83 after subtracting 304 from 387.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 304

Advancing to step 4:
When dividing 839 by 304, we get 2 with a remainder of 231.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 608 from 839 to get 231.
Take the next digit (1) from the dividend and append it to 231, then repeat: 2311 / 304

Moving on to step 5:
304 can be fit into 2311 7 times, resulting in a remainder of 183.
The next digit of our result is 7. 
Result so far: 127.0
If we take 2128 away from 2311, we end up with 183.
Append the next digit (9) from the dividend to 183 and continue with: 1839 / 304

Step 6:
304 goes into 1839 6 times with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 1276.0
Deduct 1824 from 1839 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 304

Going ahead to step 7:
The number 304 fits into 158 0 times, leaving a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 12760.0
The remainder is 158 after subtracting 0 from 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 8:
If we divide 1580 by 304, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 12760.5
The remainder is 60 after subtracting 1520 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 304, we get 1 with a remainder of 296.
Write down 1 as next digit of the result. 
Result so far: 12760.51
Subtract 304 from 600 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
304 goes into 2960 9 times with a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 12760.519
Deduct 2736 from 2960 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 11:
If we divide 2240 by 304, we get 7 and a remainder of 112.
The next digit of our result is 7. 
Result so far: 12760.5197
If we take 2128 away from 2240, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
1120 divided by 304 is 3 with a remainder of 208.
The next digit of our result is 3. 
Result so far: 12760.51973
Deduct 912 from 1120 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 13:
2080 divided by 304 is 6 with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 12760.519736
The remainder is 256 after subtracting 1824 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
If we divide 2560 by 304, we get 8 and a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 12760.5197368
Subtracting 2432 from 2560 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 15:
The number 304 fits into 1280 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 12760.51973684
Subtract 1216 from 1280 to 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.

Our division results in 12760.51973684 with a remaining 6.4e-08.
