We divide 42509186 by 378
We're looking to find how many times 378 goes into 42509186.

On to step 1:
378 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 378

Going ahead to step 2:
42 divided by 378 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 378

Moving on to step 3:
When dividing 425 by 378, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 378 from 425, we get 47.
Take the next digit (0) from the dividend and append it to 47, then repeat: 470 / 378

Advancing to step 4:
The number 378 fits into 470 1 times, leaving a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 378 from 470 leaves us with 92.
Append the next digit (9) from the dividend to 92 and continue with: 929 / 378

Step 5:
The number 378 fits into 929 2 times, leaving a remainder of 173.
The next digit of our result is 2. 
Result so far: 112.0
If we subtract 756 from 929, we get 173.
Take the next digit (1) from the dividend and append it to 173, then repeat: 1731 / 378

Step 6:
The number 378 fits into 1731 4 times, leaving a remainder of 219.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
Subtracting 1512 from 1731 leaves us with 219.
Fetch the next digit (8) from the dividend, attach it to 219 and continue: 2198 / 378

Going ahead to step 7:
378 can be fit into 2198 5 times, resulting in a remainder of 308.
The next digit of our result is 5. 
Result so far: 11245.0
Subtract 1890 from 2198 to get 308.
Grab the next digit (6) from the dividend, add it to 308, then carry on: 3086 / 378

Let's proceed to step 8:
378 can be fit into 3086 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 112458.0
The remainder is 62 after subtracting 3024 from 3086.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
620 divided by 378 is 1 with a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 112458.1
Deduct 378 from 620 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 10:
If we divide 2420 by 378, we get 6 and a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 112458.16
Subtract 2268 from 2420 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 11:
1520 divided by 378 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 112458.164
If we take 1512 away from 1520, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 378 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 112458.164
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
When dividing 800 by 378, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 112458.16402
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
If we divide 440 by 378, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 112458.164021
Deduct 378 from 440 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 15:
378 can be fit into 620 1 times, resulting in a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 112458.1640211
Deduct 378 from 620 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The quotient of the division is 112458.1640211, and the remainder is 2.42e-06.
