We're dividing 152987 by 20 
We want to figure out the number of times 152987 can be divided by 20.

Let's proceed to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 20

On to step 2:
If we divide 15 by 20, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 20

Advancing to step 3:
20 can be fit into 152 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 140 from 152 leaves us with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 20

Going ahead to step 4:
20 can be fit into 129 6 times, resulting in a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we subtract 120 from 129, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 20

Moving on to step 5:
The number 20 fits into 98 4 times, leaving a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 764.0
The remainder is 18 after subtracting 80 from 98.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 20

Step 6:
187 divided by 20 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 7649.0
Deduct 180 from 187 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
20 goes into 70 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 7649.3
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7649.35
Subtracting 100 from 100 leaves us 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:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7649.35
If we subtract 0 from 0, 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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7649.35
If we subtract 0 from 0, 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.

Our division results in 7649.35 with a remaining 0.0.
