We're dividing 43858452 by 378 
We want to divide 43858452 by 378.

Advancing to step 1:
378 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 378

On to step 2:
378 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 378

Going ahead to step 3:
378 goes into 438 1 times with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 378 from 438 leaves us with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 378

Let's proceed to step 4:
When dividing 605 by 378, we get 1 with a remainder of 227.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 378 from 605, we get 227.
Append the next digit (8) from the dividend to 227 and continue with: 2278 / 378

Going ahead to step 5:
The number 378 fits into 2278 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 2268 away from 2278, we end up with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 378

Step 6:
104 divided by 378 is 0 with a remainder of 104.
The next digit of our result is 0. 
Result so far: 1160.0
Subtracting 0 from 104 leaves us with 104.
Include the next digit (5) from the dividend after 104, then repeat: 1045 / 378

Let's proceed to step 7:
If we divide 1045 by 378, we get 2 and a remainder of 289.
The next digit of our result is 2. 
Result so far: 11602.0
If we take 756 away from 1045, we end up with 289.
Include the next digit (2) from the dividend after 289, then repeat: 2892 / 378

Moving on to step 8:
The number 378 fits into 2892 7 times, leaving a remainder of 246.
The number 7 becomes the next digit in our result. 
Result so far: 116027.0
Subtracting 2646 from 2892 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.

Step 9:
378 goes into 2460 6 times with a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 116027.6
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.

Moving on to step 10:
If we divide 1920 by 378, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 116027.65
Deduct 1890 from 1920 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
If we divide 300 by 378, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 116027.65
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 12:
3000 divided by 378 is 7 with a remainder of 354.
The next digit of our result is 7. 
Result so far: 116027.6507
Subtracting 2646 from 3000 leaves us 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.

Moving on to step 13:
The number 378 fits into 3540 9 times, leaving a remainder of 138.
Write down 9 as next digit of the result. 
Result so far: 116027.65079
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.

Advancing to step 14:
When dividing 1380 by 378, we get 3 with a remainder of 246.
Put 3 as the next digit of the answer. 
Result so far: 116027.650793
Subtract 1134 from 1380 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 15:
378 can be fit into 2460 6 times, resulting in a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 116027.6507936
Subtract 2268 from 2460 to get 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 16:
The number 378 fits into 1920 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 116027.65079365
The remainder is 30 after subtracting 1890 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 116027.65079365 with a balance of 3e-08.
