We're dividing 15702 by 20 
We want to divide 15702 by 20.

On to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Going ahead to step 2:
The number 20 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 20

Step 3:
When dividing 157 by 20, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 140 from 157 and we're left with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 20

On to step 4:
When dividing 170 by 20, we get 8 with a remainder of 10.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 160 from 170 and we're left with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 20

Going ahead to step 5:
102 divided by 20 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 785.0
The remainder is 2 after subtracting 100 from 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 6:
20 divided by 20 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 785.1
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.

Let's proceed to step 7:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 785.1
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.

Advancing to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 785.1
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 785.1 with a remainder of 0.0.
