47893172 ÷ 20 
Our goal is to divide 47893172 by 20.

Let's proceed to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 20

Let's proceed to step 2:
When dividing 47 by 20, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 47 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 20

Advancing to step 3:
78 divided by 20 is 3 with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 60 from 78, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 20

Advancing to step 4:
The number 20 fits into 189 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 239.0
Subtract 180 from 189 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 20

Step 5:
93 divided by 20 is 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 2394.0
Subtracting 80 from 93 leaves us with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 20

On to step 6:
If we divide 131 by 20, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 23946.0
Subtracting 120 from 131 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 20

Moving on to step 7:
117 divided by 20 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 239465.0
Subtract 100 from 117 to get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 20

Step 8:
If we divide 172 by 20, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 2394658.0
Subtracting 160 from 172 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 20 fits into 120 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2394658.6
Subtracting 120 from 120 leaves us 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.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2394658.6
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.

Advancing to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2394658.6
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 2394658.6 with a remainder of 0.0.
