Let's divide 149142 by 20
Our goal is to divide 149142 by 20.

Let's proceed to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 20

Step 2:
20 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 20

On to step 3:
20 goes into 149 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 140 from 149 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 20

Let's proceed to step 4:
20 goes into 91 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 80 from 91 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 20

Going ahead to step 5:
If we divide 114 by 20, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 745.0
If we take 100 away from 114, we end up with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 20

Step 6:
20 goes into 142 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 7457.0
The remainder is 2 after subtracting 140 from 142.
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.
The next digit of our result is 1. 
Result so far: 7457.1
Deduct 20 from 20 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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7457.1
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.

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: 7457.1
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.

The final result is 7457.1 with a remainder of 0.0.
