15192 ÷ 20 
We want to figure out the number of times 15192 can be divided by 20.

On 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
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 20

On to step 2:
20 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 20

Step 3:
When dividing 151 by 20, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 11 after subtracting 140 from 151.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 20

On to step 4:
The number 20 fits into 119 5 times, leaving a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we take 100 away from 119, we end up with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 20

On to step 5:
192 divided by 20 is 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 759.0
Deduct 180 from 192 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
120 divided by 20 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 759.6
Deduct 120 from 120 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 7:
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: 759.6
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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 759.6
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.

The final outcome is 759.6, with a leftover of 0.0.
