Let's divide 78488240 by 378
We want to divide 78488240 by 378.

Step 1:
7 divided by 378 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 378

Let's proceed to step 2:
The number 378 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 378

Going ahead to step 3:
378 goes into 784 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 756 from 784, we get 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 378

Step 4:
288 divided by 378 is 0 with a remainder of 288.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 288, we get 288.
Bring next digit (8) of the dividend behind the 288 and repeat the process: 2888 / 378

Going ahead to step 5:
The number 378 fits into 2888 7 times, leaving a remainder of 242.
Use 7 as the next digit of our solution. 
Result so far: 207.0
If we take 2646 away from 2888, we end up with 242.
Include the next digit (2) from the dividend after 242, then repeat: 2422 / 378

Step 6:
2422 divided by 378 is 6 with a remainder of 154.
The next digit of our result is 6. 
Result so far: 2076.0
If we subtract 2268 from 2422, we get 154.
Append the next digit (4) from the dividend to 154 and continue with: 1544 / 378

Let's proceed to step 7:
378 can be fit into 1544 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 20764.0
Deduct 1512 from 1544 and we're left with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 378

Step 8:
378 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 207640.0
Deduct 0 from 320 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 9:
378 goes into 3200 8 times with a remainder of 176.
Use 8 as the next digit of our solution. 
Result so far: 207640.8
Deduct 3024 from 3200 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 10:
378 goes into 1760 4 times with a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 207640.84
If we take 1512 away from 1760, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 11:
378 goes into 2480 6 times with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 207640.846
Deduct 2268 from 2480 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 12:
The number 378 fits into 2120 5 times, leaving a remainder of 230.
Write down 5 as next digit of the result. 
Result so far: 207640.8465
The remainder is 230 after subtracting 1890 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
When dividing 2300 by 378, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 207640.84656
If we take 2268 away from 2300, 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.

Step 14:
When dividing 320 by 378, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 207640.84656
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 15:
The number 378 fits into 3200 8 times, leaving a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 207640.8465608
Deduct 3024 from 3200 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
378 can be fit into 1760 4 times, resulting in a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 207640.84656084
Subtract 1512 from 1760 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

In conclusion, the division gives 207640.84656084 with a balance of 2.48e-07.
