We divide 615339 by 20
We want to divide 615339 by 20.

Step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 20

Moving on to step 2:
If we divide 61 by 20, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 1 after subtracting 60 from 61.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

Step 3:
If we divide 15 by 20, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 15, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 20

Step 4:
20 goes into 153 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
Deduct 140 from 153 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 20

Step 5:
20 goes into 133 6 times with a remainder of 13.
The next digit of our result is 6. 
Result so far: 3076.0
If we take 120 away from 133, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 20

Let's proceed to step 6:
The number 20 fits into 139 6 times, leaving a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 30766.0
The remainder is 19 after subtracting 120 from 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 30766.9
If we take 180 away from 190, 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.

Moving on to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 30766.95
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.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30766.95
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.

Step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30766.95
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.

The final result is 30766.95 with a remainder of 0.0.
