We divide 90947 by 20
Let's see how many times 20 fits into 90947.

Step 1:
20 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 20

Advancing to step 2:
20 goes into 90 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 80 from 90 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 20

Moving on to step 3:
20 goes into 109 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 100 from 109, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 20

Advancing to step 4:
20 can be fit into 94 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 454.0
The remainder is 14 after subtracting 80 from 94.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 20

Advancing to step 5:
If we divide 147 by 20, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 4547.0
If we take 140 away from 147, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
If we divide 70 by 20, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 4547.3
If we take 60 away from 70, we end up 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.

Going ahead to step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4547.35
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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4547.35
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 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4547.35
Subtract 0 from 0 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.

The final result is 4547.35 with a remainder of 0.0.
