We're dividing 237580 by 20 
We want to divide 237580 by 20.

Going ahead to step 1:
20 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 20

Step 2:
The number 20 fits into 23 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 20 from 23 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 20

Advancing to step 3:
The number 20 fits into 37 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 17 after subtracting 20 from 37.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 20

Let's proceed to step 4:
20 can be fit into 175 8 times, resulting in a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
Deduct 160 from 175 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 20

Step 5:
20 can be fit into 158 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 1187.0
Subtracting 140 from 158 leaves us with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 20

Advancing to step 6:
20 goes into 180 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 11879.0
If we take 180 away from 180, 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.

Going ahead to step 7:
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: 11879.0
The remainder is 0 after subtracting 0 from 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 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11879.0
The remainder is 0 after subtracting 0 from 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 11879.0, and the remainder is 0.0.
