601915 ÷ 20 
Let's see how many times 20 fits into 601915.

Let's proceed to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 20

Moving on to step 2:
The number 20 fits into 60 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 60 away from 60, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 20

Going ahead to step 3:
If we divide 1 by 20, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 20

On to step 4:
19 divided by 20 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 300.0
If we subtract 0 from 19, we get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 20

Going ahead to step 5:
191 divided by 20 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 3009.0
Deduct 180 from 191 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Moving on to step 6:
If we divide 115 by 20, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 30095.0
The remainder is 15 after subtracting 100 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
20 goes into 150 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 30095.7
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 30095.75
Deduct 100 from 100 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30095.75
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.

Going ahead to step 10:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30095.75
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.

In conclusion, the division gives 30095.75 with a balance of 0.0.
