16863636 ÷ 378 
Our goal is to divide 16863636 by 378.

Advancing to step 1:
The number 378 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 378

Step 2:
378 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 378

On to step 3:
168 divided by 378 is 0 with a remainder of 168.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 168 to get 168.
Bring next digit (6) of the dividend behind the 168 and repeat the process: 1686 / 378

Going ahead to step 4:
When dividing 1686 by 378, we get 4 with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 174 after subtracting 1512 from 1686.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 378

Going ahead to step 5:
When dividing 1743 by 378, we get 4 with a remainder of 231.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtracting 1512 from 1743 leaves us with 231.
Grab the next digit (6) from the dividend, add it to 231, then carry on: 2316 / 378

Going ahead to step 6:
378 can be fit into 2316 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 446.0
If we subtract 2268 from 2316, we get 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 378

Going ahead to step 7:
483 divided by 378 is 1 with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 4461.0
The remainder is 105 after subtracting 378 from 483.
Take the next digit (6) from the dividend and append it to 105, then repeat: 1056 / 378

On to step 8:
The number 378 fits into 1056 2 times, leaving a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 44612.0
Subtract 756 from 1056 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 9:
3000 divided by 378 is 7 with a remainder of 354.
The next digit of our result is 7. 
Result so far: 44612.7
Subtract 2646 from 3000 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
3540 divided by 378 is 9 with a remainder of 138.
The number 9 becomes the next digit in our result. 
Result so far: 44612.79
If we take 3402 away from 3540, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 11:
If we divide 1380 by 378, we get 3 and a remainder of 246.
Record the quotient 3 as the next digit in the result. 
Result so far: 44612.793
Subtracting 1134 from 1380 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 12:
378 can be fit into 2460 6 times, resulting in a remainder of 192.
Record the quotient 6 as the next digit in the result. 
Result so far: 44612.7936
Subtracting 2268 from 2460 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
378 can be fit into 1920 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 44612.79365
Subtract 1890 from 1920 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
300 divided by 378 is 0 with a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 44612.79365
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 15:
The number 378 fits into 3000 7 times, leaving a remainder of 354.
The next digit of our result is 7. 
Result so far: 44612.7936507
If we take 2646 away from 3000, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 16:
378 goes into 3540 9 times with a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 44612.79365079
Subtracting 3402 from 3540 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

In conclusion, the division gives 44612.79365079 with a balance of 1.38e-07.
