19751555 ÷ 378 
We want to divide 19751555 by 378.

On to step 1:
378 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 378

Step 2:
378 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 378

Let's proceed to step 3:
When dividing 197 by 378, we get 0 with a remainder of 197.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Bring next digit (5) of the dividend behind the 197 and repeat the process: 1975 / 378

Moving on to step 4:
The number 378 fits into 1975 5 times, leaving a remainder of 85.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 1890 from 1975 and we're left with 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 378

On to step 5:
851 divided by 378 is 2 with a remainder of 95.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 756 from 851 and we're left with 95.
Bring next digit (5) of the dividend behind the 95 and repeat the process: 955 / 378

Let's proceed to step 6:
When dividing 955 by 378, we get 2 with a remainder of 199.
Record the quotient 2 as the next digit in the result. 
Result so far: 522.0
The remainder is 199 after subtracting 756 from 955.
Append the next digit (5) from the dividend to 199 and continue with: 1995 / 378

Advancing to step 7:
When dividing 1995 by 378, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 5225.0
Deduct 1890 from 1995 and we're left with 105.
Grab the next digit (5) from the dividend, add it to 105, then carry on: 1055 / 378

Let's proceed to step 8:
1055 divided by 378 is 2 with a remainder of 299.
Record the quotient 2 as the next digit in the result. 
Result so far: 52252.0
If we take 756 away from 1055, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 9:
378 can be fit into 2990 7 times, resulting in a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 52252.7
If we take 2646 away from 2990, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 10:
3440 divided by 378 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 52252.79
Deduct 3402 from 3440 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 378, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 52252.791
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
20 divided by 378 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 52252.791
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 378, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 52252.791
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 52252.791 with a balance of 0.0002.
