86904248 ÷ 378 
We want to divide 86904248 by 378.

Step 1:
The number 378 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 378

Going ahead to step 2:
If we divide 86 by 378, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 378

Going ahead to step 3:
378 can be fit into 869 2 times, resulting in a remainder of 113.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 756 from 869, we get 113.
Take the next digit (0) from the dividend and append it to 113, then repeat: 1130 / 378

On to step 4:
1130 divided by 378 is 2 with a remainder of 374.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 756 from 1130 to get 374.
Bring next digit (4) of the dividend behind the 374 and repeat the process: 3744 / 378

Moving on to step 5:
The number 378 fits into 3744 9 times, leaving a remainder of 342.
Put 9 as the next digit of the answer. 
Result so far: 229.0
Subtract 3402 from 3744 to get 342.
Include the next digit (2) from the dividend after 342, then repeat: 3422 / 378

Step 6:
The number 378 fits into 3422 9 times, leaving a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 2299.0
Deduct 3402 from 3422 and we're left with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 378

On to step 7:
378 goes into 204 0 times with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 22990.0
Subtracting 0 from 204 leaves us with 204.
Append the next digit (8) from the dividend to 204 and continue with: 2048 / 378

Moving on to step 8:
378 can be fit into 2048 5 times, resulting in a remainder of 158.
Write down 5 as next digit of the result. 
Result so far: 229905.0
If we take 1890 away from 2048, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 9:
The number 378 fits into 1580 4 times, leaving a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 229905.4
Subtracting 1512 from 1580 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
The number 378 fits into 680 1 times, leaving a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 229905.41
Subtract 378 from 680 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 11:
If we divide 3020 by 378, we get 7 and a remainder of 374.
The number 7 becomes the next digit in our result. 
Result so far: 229905.417
The remainder is 374 after subtracting 2646 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 12:
If we divide 3740 by 378, we get 9 and a remainder of 338.
Use 9 as the next digit of our solution. 
Result so far: 229905.4179
Subtracting 3402 from 3740 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 13:
The number 378 fits into 3380 8 times, leaving a remainder of 356.
Record the quotient 8 as the next digit in the result. 
Result so far: 229905.41798
If we take 3024 away from 3380, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 14:
If we divide 3560 by 378, we get 9 and a remainder of 158.
Use 9 as the next digit of our solution. 
Result so far: 229905.417989
The remainder is 158 after subtracting 3402 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 15:
378 can be fit into 1580 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 229905.4179894
If we take 1512 away from 1580, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 16:
If we divide 680 by 378, we get 1 and a remainder of 302.
Write down 1 as next digit of the result. 
Result so far: 229905.41798941
The remainder is 302 after subtracting 378 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Our division results in 229905.41798941 with a remaining 3.02e-07.
