47890183 ÷ 20 
We want to figure out the number of times 47890183 can be divided by 20.

Moving on to step 1:
20 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 20

Let's proceed to step 2:
The number 20 fits into 47 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 40 from 47 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Step 3:
20 can be fit into 78 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 60 from 78, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 20

Step 4:
When dividing 189 by 20, we get 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
The remainder is 9 after subtracting 180 from 189.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 20

Going ahead to step 5:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 2394.0
Subtract 80 from 90 to get 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 20

Going ahead to step 6:
20 can be fit into 101 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 23945.0
If we subtract 100 from 101, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 20

Advancing to step 7:
If we divide 18 by 20, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 239450.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 20

Going ahead to step 8:
183 divided by 20 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 2394509.0
If we subtract 180 from 183, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
20 can be fit into 30 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 2394509.1
Deduct 20 from 30 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2394509.15
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2394509.15
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2394509.15
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2394509.15 with a remainder of 0.0.
