47945375 ÷ 18 
Let's see how many times 18 fits into 47945375.

Step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 18

Moving on to step 2:
47 divided by 18 is 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 36 from 47 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 18

On to step 3:
18 goes into 119 6 times with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 11 after subtracting 108 from 119.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 18

Going ahead to step 4:
18 can be fit into 114 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 266.0
If we take 108 away from 114, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 18

Step 5:
65 divided by 18 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 2663.0
Deduct 54 from 65 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 18

On to step 6:
113 divided by 18 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 26636.0
Subtract 108 from 113 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 18

On to step 7:
18 can be fit into 57 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 266363.0
If we subtract 54 from 57, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 18

Advancing to step 8:
18 goes into 35 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 2663631.0
Subtract 18 from 35 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
If we divide 170 by 18, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 2663631.9
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2663631.94
Subtracting 72 from 80 leaves us 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.

Step 11:
18 goes into 80 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2663631.944
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 2663631.944 with a remainder of 0.0008.
