We look at the division of 30159196 by 378 
We want to divide 30159196 by 378.

On to step 1:
When dividing 3 by 378, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 378

Advancing to step 2:
30 divided by 378 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 378

Going ahead to step 3:
If we divide 301 by 378, we get 0 and a remainder of 301.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 301 after subtracting 0 from 301.
Append the next digit (5) from the dividend to 301 and continue with: 3015 / 378

Advancing to step 4:
When dividing 3015 by 378, we get 7 with a remainder of 369.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 2646 away from 3015, we end up with 369.
Take the next digit (9) from the dividend and append it to 369, then repeat: 3699 / 378

Moving on to step 5:
3699 divided by 378 is 9 with a remainder of 297.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 3402 from 3699 to get 297.
Append the next digit (1) from the dividend to 297 and continue with: 2971 / 378

Step 6:
2971 divided by 378 is 7 with a remainder of 325.
The number 7 becomes the next digit in our result. 
Result so far: 797.0
Subtracting 2646 from 2971 leaves us with 325.
Bring next digit (9) of the dividend behind the 325 and repeat the process: 3259 / 378

Step 7:
3259 divided by 378 is 8 with a remainder of 235.
Use 8 as the next digit of our solution. 
Result so far: 7978.0
If we subtract 3024 from 3259, we get 235.
Append the next digit (6) from the dividend to 235 and continue with: 2356 / 378

Step 8:
378 can be fit into 2356 6 times, resulting in a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 79786.0
If we take 2268 away from 2356, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 9:
When dividing 880 by 378, we get 2 with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 79786.2
Subtract 756 from 880 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
If we divide 1240 by 378, we get 3 and a remainder of 106.
Record the quotient 3 as the next digit in the result. 
Result so far: 79786.23
Subtract 1134 from 1240 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 11:
The number 378 fits into 1060 2 times, leaving a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 79786.232
If we subtract 756 from 1060, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 12:
378 goes into 3040 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 79786.2328
If we subtract 3024 from 3040, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
The number 378 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 79786.2328
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 14:
When dividing 1600 by 378, we get 4 with a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 79786.232804
Subtract 1512 from 1600 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 15:
378 goes into 880 2 times with a remainder of 124.
Record the quotient 2 as the next digit in the result. 
Result so far: 79786.2328042
If we take 756 away from 880, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 16:
1240 divided by 378 is 3 with a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 79786.23280423
If we subtract 1134 from 1240, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The quotient of the division is 79786.23280423, and the remainder is 1.06e-07.
