We look at the division of 18378015 by 443 
Our goal is to divide 18378015 by 443.

Advancing to step 1:
If we divide 1 by 443, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 443

Let's proceed to step 2:
443 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 443

Advancing to step 3:
183 divided by 443 is 0 with a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Bring next digit (7) of the dividend behind the 183 and repeat the process: 1837 / 443

On to step 4:
If we divide 1837 by 443, we get 4 and a remainder of 65.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1772 away from 1837, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 443

On to step 5:
658 divided by 443 is 1 with a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 443 from 658 to get 215.
Grab the next digit (0) from the dividend, add it to 215, then carry on: 2150 / 443

Moving on to step 6:
The number 443 fits into 2150 4 times, leaving a remainder of 378.
Put 4 as the next digit of the answer. 
Result so far: 414.0
The remainder is 378 after subtracting 1772 from 2150.
Fetch the next digit (1) from the dividend, attach it to 378 and continue: 3781 / 443

Let's proceed to step 7:
3781 divided by 443 is 8 with a remainder of 237.
Use 8 as the next digit of our solution. 
Result so far: 4148.0
The remainder is 237 after subtracting 3544 from 3781.
Fetch the next digit (5) from the dividend, attach it to 237 and continue: 2375 / 443

Step 8:
If we divide 2375 by 443, we get 5 and a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 41485.0
The remainder is 160 after subtracting 2215 from 2375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
443 goes into 1600 3 times with a remainder of 271.
Use 3 as the next digit of our solution. 
Result so far: 41485.3
Subtracting 1329 from 1600 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 10:
2710 divided by 443 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 41485.36
If we subtract 2658 from 2710, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
443 can be fit into 520 1 times, resulting in a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 41485.361
Deduct 443 from 520 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 12:
When dividing 770 by 443, we get 1 with a remainder of 327.
The number 1 becomes the next digit in our result. 
Result so far: 41485.3611
The remainder is 327 after subtracting 443 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

The final result is 41485.3611 with a remainder of 0.00327.
