We're dividing 307419 by 20 
Let's see how many times 20 fits into 307419.

Advancing to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 20

Advancing to step 2:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 20 away from 30, we end up with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 20

Going ahead to step 3:
If we divide 107 by 20, we get 5 and a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 100 away from 107, we end up with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 20

Going ahead to step 4:
If we divide 74 by 20, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 60 from 74 and we're left with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 20

Moving on to step 5:
If we divide 141 by 20, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 1537.0
If we subtract 140 from 141, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 20

Advancing to step 6:
The number 20 fits into 19 0 times, leaving a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 15370.0
Deduct 0 from 19 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
20 goes into 190 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 15370.9
If we subtract 180 from 190, 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.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15370.95
The remainder is 0 after subtracting 100 from 100.
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15370.95
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 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15370.95
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.

In conclusion, the division gives 15370.95 with a balance of 0.0.
