We're dividing 6142 by 20 
We want to figure out the number of times 6142 can be divided by 20.

Step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 20

Moving on to step 2:
If we divide 61 by 20, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 60 from 61 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Moving on to step 3:
If we divide 14 by 20, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 14 and we're left with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 20

Let's proceed to step 4:
142 divided by 20 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 307.0
Subtract 140 from 142 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.

Step 5:
When dividing 20 by 20, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 307.1
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.

Going ahead to step 6:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 307.1
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.

Moving on to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 307.1
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 quotient of the division is 307.1, and the remainder is 0.0.
