We're dividing 975142 by 20 
We're looking to find how many times 20 goes into 975142.

Step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 20

Advancing to step 2:
If we divide 97 by 20, we get 4 and a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 97, we get 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

Going ahead to step 3:
20 goes into 175 8 times with a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 15 after subtracting 160 from 175.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 20

Moving on to step 4:
20 goes into 151 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 487.0
If we take 140 away from 151, we end up with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 20

On to step 5:
If we divide 114 by 20, we get 5 and a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 4875.0
Subtract 100 from 114 to get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 20

Going ahead to step 6:
20 goes into 142 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 48757.0
Subtracting 140 from 142 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 20 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 48757.1
If we take 20 away from 20, 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.

On 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: 48757.1
If we take 0 away from 0, 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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48757.1
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.

The final result is 48757.1 with a remainder of 0.0.
