378156 divided by 78 
We want to divide 378156 by 78.

Moving on to step 1:
If we divide 3 by 78, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 78

Advancing to step 2:
The number 78 fits into 37 0 times, leaving a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Grab the next digit (8) from the dividend, add it to 37, then carry on: 378 / 78

Let's proceed to step 3:
378 divided by 78 is 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 312 away from 378, we end up with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 78

Going ahead to step 4:
78 can be fit into 661 8 times, resulting in a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtracting 624 from 661 leaves us with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 78

Going ahead to step 5:
78 can be fit into 375 4 times, resulting in a remainder of 63.
The next digit of our result is 4. 
Result so far: 484.0
If we subtract 312 from 375, we get 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 78

Let's proceed to step 6:
The number 78 fits into 636 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 4848.0
Deduct 624 from 636 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
78 goes into 120 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 4848.1
If we take 78 away from 120, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
The number 78 fits into 420 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 4848.15
If we subtract 390 from 420, we 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.

Going ahead to step 9:
When dividing 300 by 78, we get 3 with a remainder of 66.
The next digit of our result is 3. 
Result so far: 4848.153
The remainder is 66 after subtracting 234 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
660 divided by 78 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 4848.1538
Subtract 624 from 660 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
The number 78 fits into 360 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4848.15384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
The number 78 fits into 480 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 4848.153846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 78, we get 1 with a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 4848.1538461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
If we divide 420 by 78, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 4848.15384615
Subtract 390 from 420 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.

The final outcome is 4848.15384615, with a leftover of 3e-08.
