237188 ÷ 20 
Our goal is to divide 237188 by 20.

Let's proceed to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 20

Step 2:
20 can be fit into 23 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 20 away from 23, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 20

Step 3:
If we divide 37 by 20, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 17 after subtracting 20 from 37.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 20

Going ahead to step 4:
The number 20 fits into 171 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 160 from 171 and we're left with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 20

Going ahead to step 5:
The number 20 fits into 118 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 1185.0
The remainder is 18 after subtracting 100 from 118.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 20

Let's proceed to step 6:
20 can be fit into 188 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 11859.0
The remainder is 8 after subtracting 180 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 11859.4
The remainder is 0 after subtracting 80 from 80.
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 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11859.4
Subtract 0 from 0 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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11859.4
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.

The quotient of the division is 11859.4, and the remainder is 0.0.
