47932900 ÷ 20 
We want to figure out the number of times 47932900 can be divided by 20.

Step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 20

On to step 2:
When dividing 47 by 20, we get 2 with 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.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 20

Moving on to step 3:
20 can be fit into 79 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 60 from 79, we get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 20

On to step 4:
20 can be fit into 193 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 239.0
The remainder is 13 after subtracting 180 from 193.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 20

Moving on to step 5:
20 can be fit into 132 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2396.0
If we take 120 away from 132, we end up with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 20

Step 6:
When dividing 129 by 20, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 23966.0
If we subtract 120 from 129, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Let's proceed to step 7:
When dividing 90 by 20, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 239664.0
Subtract 80 from 90 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 20

Let's proceed to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2396645.0
If we subtract 100 from 100, 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2396645.0
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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2396645.0
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.

The final outcome is 2396645.0, with a leftover of 0.0.
