We divide 550053 by 87
We want to figure out the number of times 550053 can be divided by 87.

Step 1:
If we divide 5 by 87, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 87

Step 2:
87 can be fit into 55 0 times, resulting in a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 87

Advancing to step 3:
If we divide 550 by 87, we get 6 and a remainder of 28.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 28 after subtracting 522 from 550.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 87

On to step 4:
87 goes into 280 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 261 from 280 leaves us with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 87

Let's proceed to step 5:
87 goes into 195 2 times with a remainder of 21.
The next digit of our result is 2. 
Result so far: 632.0
Deduct 174 from 195 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 87

Moving on to step 6:
213 divided by 87 is 2 with a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 6322.0
If we subtract 174 from 213, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 6322.4
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
87 goes into 420 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 6322.44
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 6322.44 with a remaining 0.072.
