We look at the division of 748642 by 20 
We're looking to find how many times 20 goes into 748642.

Going ahead to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 20

Let's proceed to step 2:
The number 20 fits into 74 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 60 from 74 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 20

On to step 3:
20 can be fit into 148 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
If we take 140 away from 148, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 20

Moving on to step 4:
20 can be fit into 86 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
Deduct 80 from 86 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 20

On to step 5:
When dividing 64 by 20, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3743.0
The remainder is 4 after subtracting 60 from 64.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 20

Step 6:
The number 20 fits into 42 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 37432.0
Subtract 40 from 42 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 can be fit into 20 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 37432.1
If we subtract 20 from 20, 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.

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: 37432.1
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.

Let's proceed to 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: 37432.1
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.

In conclusion, the division gives 37432.1 with a balance of 0.0.
