We're dividing 162603 by 87 
We want to divide 162603 by 87.

Advancing to step 1:
1 divided by 87 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 87

Let's proceed to step 2:
16 divided by 87 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 87

Moving on to step 3:
If we divide 162 by 87, we get 1 and a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 87 from 162 leaves us with 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 87

On to step 4:
87 can be fit into 756 8 times, resulting in a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 696 away from 756, we end up with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 87

Step 5:
The number 87 fits into 600 6 times, leaving a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 186.0
Subtract 522 from 600 to get 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 87

Moving on to step 6:
87 can be fit into 783 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1869.0
If we take 783 away from 783, 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.

Going ahead to step 7:
When dividing 0 by 87, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1869.0
Subtracting 0 from 0 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.

Moving on to step 8:
The number 87 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1869.0
Subtracting 0 from 0 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.

After the division, we end up with 1869.0 and a remainder of 0.0.
