609172 divided by 20 
We're looking to find how many times 20 goes into 609172.

On to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 20

Going ahead to step 2:
If we divide 60 by 20, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 60 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 20

Going ahead to step 3:
If we divide 9 by 20, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 20

Advancing to step 4:
If we divide 91 by 20, we get 4 and a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 304.0
Subtracting 80 from 91 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 20

On to step 5:
20 goes into 117 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 3045.0
Subtract 100 from 117 to get 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 20

On to step 6:
172 divided by 20 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 30458.0
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.

Moving on to step 7:
120 divided by 20 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 30458.6
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.

Let's proceed to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30458.6
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.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30458.6
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.

In conclusion, the division gives 30458.6 with a balance of 0.0.
