We divide 47645489 by 20
We want to divide 47645489 by 20.

Advancing to step 1:
4 divided by 20 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in 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 / 20

Advancing to step 2:
The number 20 fits into 47 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 40 from 47, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 20

Moving on to step 3:
76 divided by 20 is 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 16 after subtracting 60 from 76.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 20

Let's proceed to step 4:
20 can be fit into 164 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 238.0
Subtracting 160 from 164 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Advancing to step 5:
When dividing 45 by 20, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2382.0
The remainder is 5 after subtracting 40 from 45.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 20

Moving on to step 6:
When dividing 54 by 20, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 23822.0
If we take 40 away from 54, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 20

Moving on to step 7:
148 divided by 20 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 238227.0
If we take 140 away from 148, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 20

Let's proceed to step 8:
20 goes into 89 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 2382274.0
If we subtract 80 from 89, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 20, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 2382274.4
Deduct 80 from 90 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.

Advancing to step 10:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2382274.45
Subtract 100 from 100 to 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:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2382274.45
Subtracting 0 from 0 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 12:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2382274.45
If we take 0 away from 0, we end up 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.

After the division, we end up with 2382274.45 and a remainder of 0.0.
