378 can be fit into 365 0 times, resulting in a remainder of 365.
Use 0 as the next digit of our solution. 
Result so far: 20.0
The remainder is 365 after subtracting 0 from 365.
Take the next digit (7) from the dividend and append it to 365, then repeat: 3657 / 378

On to step 5:
3657 divided by 378 is 9 with a remainder of 255.
Use 9 as the next digit of our solution. 
Result so far: 209.0
If we subtract 3402 from 3657, we get 255.
Fetch the next digit (2) from the dividend, attach it to 255 and continue: 2552 / 378

Moving on to step 6:
2552 divided by 378 is 6 with a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 2096.0
If we take 2268 away from 2552, we end up with 284.
Append the next digit (1) from the dividend to 284 and continue with: 2841 / 378

On to step 7:
When dividing 2841 by 378, we get 7 with a remainder of 195.
The number 7 becomes the next digit in our result. 
Result so far: 20967.0
The remainder is 195 after subtracting 2646 from 2841.
Include the next digit (5) from the dividend after 195, then repeat: 1955 / 378

Let's proceed to step 8:
The number 378 fits into 1955 5 times, leaving a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 209675.0
Deduct 1890 from 1955 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 9:
650 divided by 378 is 1 with a remainder of 272.
Write down 1 as next digit of the result. 
Result so far: 209675.1
Subtract 378 from 650 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 10:
When dividing 2720 by 378, we get 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 209675.17
If we subtract 2646 from 2720, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
The number 378 fits into 740 1 times, leaving a remainder of 362.
Record the quotient 1 as the next digit in the result. 
Result so far: 209675.171
The remainder is 362 after subtracting 378 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 12:
378 can be fit into 3620 9 times, resulting in a remainder of 218.
Write down 9 as next digit of the result. 
Result so far: 209675.1719
If we subtract 3402 from 3620, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 13:
2180 divided by 378 is 5 with a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 209675.17195
If we take 1890 away from 2180, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 14:
378 can be fit into 2900 7 times, resulting in a remainder of 254.
Use 7 as the next digit of our solution. 
Result so far: 209675.171957
Deduct 2646 from 2900 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 15:
378 can be fit into 2540 6 times, resulting in a remainder of 272.
Use 6 as the next digit of our solution. 
Result so far: 209675.1719576
The remainder is 272 after subtracting 2268 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 16:
When dividing 2720 by 378, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 209675.17195767
If we subtract 2646 from 2720, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

In conclusion, the division gives 209675.17195767 with a balance of 7.4e-08.
