98349863 ÷ 378 
Our goal is to divide 98349863 by 378.

Going ahead to step 1:
378 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 378

Advancing to step 2:
When dividing 98 by 378, we get 0 with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Fetch the next digit (3) from the dividend, attach it to 98 and continue: 983 / 378

Let's proceed to step 3:
When dividing 983 by 378, we get 2 with a remainder of 227.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 756 from 983 and we're left with 227.
Include the next digit (4) from the dividend after 227, then repeat: 2274 / 378

Moving on to step 4:
2274 divided by 378 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 2268 from 2274 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 378

Going ahead to step 5:
If we divide 69 by 378, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
If we take 0 away from 69, we end up with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 378

Let's proceed to step 6:
698 divided by 378 is 1 with a remainder of 320.
Use 1 as the next digit of our solution. 
Result so far: 2601.0
The remainder is 320 after subtracting 378 from 698.
Grab the next digit (6) from the dividend, add it to 320, then carry on: 3206 / 378

Step 7:
If we divide 3206 by 378, we get 8 and a remainder of 182.
Write down 8 as next digit of the result. 
Result so far: 26018.0
If we subtract 3024 from 3206, we get 182.
Bring next digit (3) of the dividend behind the 182 and repeat the process: 1823 / 378

Going ahead to step 8:
If we divide 1823 by 378, we get 4 and a remainder of 311.
The next digit of our result is 4. 
Result so far: 260184.0
Subtract 1512 from 1823 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 9:
If we divide 3110 by 378, we get 8 and a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 260184.8
If we subtract 3024 from 3110, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
The number 378 fits into 860 2 times, leaving a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 260184.82
If we take 756 away from 860, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 11:
When dividing 1040 by 378, we get 2 with a remainder of 284.
Record the quotient 2 as the next digit in the result. 
Result so far: 260184.822
Subtract 756 from 1040 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 260184.822 with a balance of 0.0284.
