Let's divide 150370 by 20
We want to figure out the number of times 150370 can be divided by 20.

Going ahead to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Advancing to step 2:
20 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 20

Moving on to step 3:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 140 from 150 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 20

Advancing to step 4:
20 can be fit into 103 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 100 from 103, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

Going ahead to step 5:
37 divided by 20 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 751.0
Subtract 20 from 37 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 20

Step 6:
20 goes into 170 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 7518.0
Deduct 160 from 170 and we're left 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.

On to step 7:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7518.5
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.

Moving on to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7518.5
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.

Step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7518.5
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.

After the division, we end up with 7518.5 and a remainder of 0.0.
