610369 ÷ 20 
We're looking to find how many times 20 goes into 610369.

Going ahead to step 1:
20 goes into 6 0 times with 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.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 20

Advancing to step 2:
61 divided by 20 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 61 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 20

Moving on to step 3:
If we divide 10 by 20, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 10 to get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 20

Advancing to step 4:
When dividing 103 by 20, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 305.0
The remainder is 3 after subtracting 100 from 103.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 20

On to step 5:
36 divided by 20 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 3051.0
If we take 20 away from 36, we end up with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 20

On to step 6:
20 goes into 169 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 30518.0
Subtracting 160 from 169 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 30518.4
The remainder is 10 after subtracting 80 from 90.
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 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 30518.45
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30518.45
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.

Moving on to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30518.45
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.

The quotient of the division is 30518.45, and the remainder is 0.0.
