Let's divide 81178418 by 378
We want to divide 81178418 by 378.

Moving on to step 1:
When dividing 8 by 378, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 378

On to step 2:
When dividing 81 by 378, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 378

On to step 3:
The number 378 fits into 811 2 times, leaving a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 756 from 811 and we're left with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 378

On to step 4:
If we divide 557 by 378, we get 1 and a remainder of 179.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 378 from 557 to get 179.
Grab the next digit (8) from the dividend, add it to 179, then carry on: 1798 / 378

Let's proceed to step 5:
The number 378 fits into 1798 4 times, leaving a remainder of 286.
The next digit of our result is 4. 
Result so far: 214.0
Subtracting 1512 from 1798 leaves us with 286.
Bring next digit (4) of the dividend behind the 286 and repeat the process: 2864 / 378

Step 6:
When dividing 2864 by 378, we get 7 with a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 2147.0
Deduct 2646 from 2864 and we're left with 218.
Fetch the next digit (1) from the dividend, attach it to 218 and continue: 2181 / 378

Going ahead to step 7:
The number 378 fits into 2181 5 times, leaving a remainder of 291.
The number 5 becomes the next digit in our result. 
Result so far: 21475.0
Deduct 1890 from 2181 and we're left with 291.
Include the next digit (8) from the dividend after 291, then repeat: 2918 / 378

Step 8:
378 goes into 2918 7 times with a remainder of 272.
Write down 7 as next digit of the result. 
Result so far: 214757.0
Deduct 2646 from 2918 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 9:
378 goes into 2720 7 times with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 214757.7
Deduct 2646 from 2720 and we're left with 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 10:
If we divide 740 by 378, we get 1 and a remainder of 362.
Record the quotient 1 as the next digit in the result. 
Result so far: 214757.71
Subtracting 378 from 740 leaves us with 362.
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 11:
378 can be fit into 3620 9 times, resulting in a remainder of 218.
Use 9 as the next digit of our solution. 
Result so far: 214757.719
Subtract 3402 from 3620 to 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 12:
If we divide 2180 by 378, we get 5 and a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 214757.7195
Subtracting 1890 from 2180 leaves us 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.

Advancing to step 13:
When dividing 2900 by 378, we get 7 with a remainder of 254.
The next digit of our result is 7. 
Result so far: 214757.71957
If we subtract 2646 from 2900, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 14:
378 can be fit into 2540 6 times, resulting in a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 214757.719576
Deduct 2268 from 2540 and we're left with 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 15:
2720 divided by 378 is 7 with a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 214757.7195767
The remainder is 74 after subtracting 2646 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 16:
When dividing 740 by 378, we get 1 with a remainder of 362.
Use 1 as the next digit of our solution. 
Result so far: 214757.71957671
If we take 378 away from 740, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

The quotient of the division is 214757.71957671, and the remainder is 3.62e-07.
