Let's divide 74257 by 20
Our goal is to divide 74257 by 20.

Going ahead to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 20

Let's proceed to step 2:
20 goes into 74 3 times with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 60 from 74 leaves us with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 20

Step 3:
If we divide 142 by 20, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 140 from 142 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 20

Going ahead to step 4:
When dividing 25 by 20, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 371.0
Deduct 20 from 25 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

Step 5:
20 goes into 57 2 times with a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 3712.0
Subtracting 40 from 57 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 6:
If we divide 170 by 20, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 3712.8
Subtracting 160 from 170 leaves us 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.

Step 7:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 3712.85
Deduct 100 from 100 and we're left 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:
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: 3712.85
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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3712.85
Deduct 0 from 0 and we're left 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 3712.85 with a remainder of 0.0.
