We want to divide 17985518 by 442.

Step 1:
The number 442 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 442

Moving on to step 2:
442 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 442

On to step 3:
179 divided by 442 is 0 with a remainder of 179.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 179 and we're left with 179.
Include the next digit (8) from the dividend after 179, then repeat: 1798 / 442

Step 4:
442 goes into 1798 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1768 from 1798 and we're left with 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 442

Advancing to step 5:
305 divided by 442 is 0 with a remainder of 305.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtract 0 from 305 to get 305.
Include the next digit (5) from the dividend after 305, then repeat: 3055 / 442

Advancing to step 6:
3055 divided by 442 is 6 with a remainder of 403.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
If we subtract 2652 from 3055, we get 403.
Bring next digit (1) of the dividend behind the 403 and repeat the process: 4031 / 442

Going ahead to step 7:
4031 divided by 442 is 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 4069.0
Deduct 3978 from 4031 and we're left with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 442

Going ahead to step 8:
538 divided by 442 is 1 with a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 40691.0
Subtracting 442 from 538 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 9:
The number 442 fits into 960 2 times, leaving a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 40691.2
The remainder is 76 after subtracting 884 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
442 goes into 760 1 times with a remainder of 318.
Put 1 as the next digit of the answer. 
Result so far: 40691.21
If we subtract 442 from 760, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 11:
442 can be fit into 3180 7 times, resulting in a remainder of 86.
Put 7 as the next digit of the answer. 
Result so far: 40691.217
Subtract 3094 from 3180 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 12:
442 can be fit into 860 1 times, resulting in a remainder of 418.
Record the quotient 1 as the next digit in the result. 
Result so far: 40691.2171
If we take 442 away from 860, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 13:
The number 442 fits into 4180 9 times, leaving a remainder of 202.
Use 9 as the next digit of our solution. 
Result so far: 40691.21719
The remainder is 202 after subtracting 3978 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 14:
442 can be fit into 2020 4 times, resulting in a remainder of 252.
Record the quotient 4 as the next digit in the result. 
Result so far: 40691.217194
The remainder is 252 after subtracting 1768 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 15:
The number 442 fits into 2520 5 times, leaving a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 40691.2171945
Subtracting 2210 from 2520 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 16:
If we divide 3100 by 442, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 40691.21719457
Subtracting 3094 from 3100 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 40691.21719457 with a remaining 6e-09.
