We divide 609572 by 20
Let's see how many times 20 fits into 609572.

Step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 20

Let's proceed to step 2:
20 can be fit into 60 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 0 after subtracting 60 from 60.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 20

Step 3:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 9 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 20

Advancing to step 4:
20 can be fit into 95 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 304.0
The remainder is 15 after subtracting 80 from 95.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 20

Step 5:
20 can be fit into 157 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 3047.0
Deduct 140 from 157 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 20

Moving on to step 6:
When dividing 172 by 20, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 30478.0
The remainder is 12 after subtracting 160 from 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 20, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 30478.6
Deduct 120 from 120 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 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30478.6
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30478.6
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.

The final outcome is 30478.6, with a leftover of 0.0.
