We're dividing 306951 by 20 
We want to divide 306951 by 20.

Advancing to step 1:
3 divided by 20 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 20

Step 2:
When dividing 30 by 20, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 20 from 30 leaves us with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 20

Step 3:
The number 20 fits into 106 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 100 from 106 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 20

Advancing to step 4:
20 goes into 69 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtracting 60 from 69 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 20

Step 5:
95 divided by 20 is 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 1534.0
Subtract 80 from 95 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 20

Let's proceed to step 6:
151 divided by 20 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 15347.0
Deduct 140 from 151 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 15347.5
If we subtract 100 from 110, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15347.55
If we subtract 100 from 100, 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.

Our division results in 15347.55 with a remaining 0.0.
