We look at the division of 17244880 by 378 
We're looking to find how many times 378 goes into 17244880.

Let's proceed to step 1:
1 divided by 378 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 378

On to step 2:
378 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 378

Let's proceed to step 3:
If we divide 172 by 378, we get 0 and a remainder of 172.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 172, we get 172.
Append the next digit (4) from the dividend to 172 and continue with: 1724 / 378

Step 4:
If we divide 1724 by 378, we get 4 and a remainder of 212.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 212 after subtracting 1512 from 1724.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 378

On to step 5:
2124 divided by 378 is 5 with a remainder of 234.
The next digit of our result is 5. 
Result so far: 45.0
Deduct 1890 from 2124 and we're left with 234.
Append the next digit (8) from the dividend to 234 and continue with: 2348 / 378

Going ahead to step 6:
If we divide 2348 by 378, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 456.0
If we subtract 2268 from 2348, we get 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 378

Moving on to step 7:
808 divided by 378 is 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 4562.0
If we subtract 756 from 808, we get 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 378

Step 8:
The number 378 fits into 520 1 times, leaving a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 45621.0
Deduct 378 from 520 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 9:
When dividing 1420 by 378, we get 3 with a remainder of 286.
The next digit of our result is 3. 
Result so far: 45621.3
Deduct 1134 from 1420 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Step 10:
378 can be fit into 2860 7 times, resulting in a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 45621.37
Subtracting 2646 from 2860 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
When dividing 2140 by 378, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 45621.375
If we subtract 1890 from 2140, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
The number 378 fits into 2500 6 times, leaving a remainder of 232.
Put 6 as the next digit of the answer. 
Result so far: 45621.3756
Subtract 2268 from 2500 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 13:
When dividing 2320 by 378, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 45621.37566
Deduct 2268 from 2320 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 45621.37566 and a remainder of 5.2e-05.
