603520 ÷ 87 
Our goal is to divide 603520 by 87.

Moving on to step 1:
87 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 87

Going ahead to step 2:
60 divided by 87 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 87

Moving on to step 3:
If we divide 603 by 87, we get 6 and a remainder of 81.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 522 from 603 and we're left with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 87

Going ahead to step 4:
87 can be fit into 815 9 times, resulting in a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 783 away from 815, we end up with 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 87

Going ahead to step 5:
322 divided by 87 is 3 with a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 693.0
The remainder is 61 after subtracting 261 from 322.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 87

Going ahead to step 6:
87 can be fit into 610 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 6937.0
Deduct 609 from 610 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
87 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6937.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 87, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 6937.01
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
130 divided by 87 is 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 6937.011
If we subtract 87 from 130, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 6937.011, and the remainder is 0.0043.
