We divide 15888151 by 378
We want to figure out the number of times 15888151 can be divided by 378.

Moving on to step 1:
378 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 378

Step 2:
15 divided by 378 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 378

Advancing to step 3:
378 can be fit into 158 0 times, resulting in a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 158, we get 158.
Fetch the next digit (8) from the dividend, attach it to 158 and continue: 1588 / 378

Let's proceed to step 4:
378 can be fit into 1588 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1512 from 1588, we get 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 378

Step 5:
If we divide 768 by 378, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 756 from 768 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 378

Going ahead to step 6:
378 can be fit into 121 0 times, resulting in a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 420.0
The remainder is 121 after subtracting 0 from 121.
Include the next digit (5) from the dividend after 121, then repeat: 1215 / 378

Moving on to step 7:
378 can be fit into 1215 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 4203.0
Deduct 1134 from 1215 and we're left with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 378

Going ahead to step 8:
When dividing 811 by 378, we get 2 with a remainder of 55.
Write down 2 as next digit of the result. 
Result so far: 42032.0
The remainder is 55 after subtracting 756 from 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 9:
378 can be fit into 550 1 times, resulting in a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 42032.1
Subtract 378 from 550 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
378 can be fit into 1720 4 times, resulting in a remainder of 208.
The next digit of our result is 4. 
Result so far: 42032.14
If we subtract 1512 from 1720, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
378 goes into 2080 5 times with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 42032.145
Deduct 1890 from 2080 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 12:
378 can be fit into 1900 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 42032.1455
If we subtract 1890 from 1900, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 42032.1455 with a balance of 0.0001.
