Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 378

Going ahead to step 3:
When dividing 184 by 378, we get 0 with a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 184 and we're left with 184.
Grab the next digit (0) from the dividend, add it to 184, then carry on: 1840 / 378

Moving on to step 4:
1840 divided by 378 is 4 with a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 1512 from 1840, we get 328.
Grab the next digit (8) from the dividend, add it to 328, then carry on: 3288 / 378

Step 5:
The number 378 fits into 3288 8 times, leaving a remainder of 264.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 3024 from 3288 and we're left with 264.
Bring next digit (6) of the dividend behind the 264 and repeat the process: 2646 / 378

On to step 6:
If we divide 2646 by 378, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Subtract 2646 from 2646 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 378

Let's proceed to step 7:
The number 378 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 4870.0
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 378

Moving on to step 8:
378 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 48700.0
The remainder is 24 after subtracting 0 from 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
When dividing 240 by 378, we get 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 48700.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
When dividing 2400 by 378, we get 6 with a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 48700.06
Subtract 2268 from 2400 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 11:
378 can be fit into 1320 3 times, resulting in a remainder of 186.
Use 3 as the next digit of our solution. 
Result so far: 48700.063
If we take 1134 away from 1320, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 12:
1860 divided by 378 is 4 with a remainder of 348.
Write down 4 as next digit of the result. 
Result so far: 48700.0634
If we subtract 1512 from 1860, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 13:
378 goes into 3480 9 times with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 48700.06349
The remainder is 78 after subtracting 3402 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
When dividing 780 by 378, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 48700.063492
Subtract 756 from 780 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
If we divide 240 by 378, we get 0 and a remainder of 240.
The next digit of our result is 0. 
Result so far: 48700.063492
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
The number 378 fits into 2400 6 times, leaving a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 48700.06349206
The remainder is 132 after subtracting 2268 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

In conclusion, the division gives 48700.06349206 with a balance of 1.32e-07.
