We're dividing 545712 by 87 
We want to figure out the number of times 545712 can be divided by 87.

Let's proceed to step 1:
5 divided by 87 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 87

On to step 2:
The number 87 fits into 54 0 times, leaving a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 87

Let's proceed to step 3:
When dividing 545 by 87, we get 6 with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 522 from 545, we get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 87

Let's proceed to step 4:
87 can be fit into 237 2 times, resulting in a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 174 away from 237, we end up with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 87

Let's proceed to step 5:
When dividing 631 by 87, we get 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 627.0
Subtract 609 from 631 to get 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 87

Let's proceed to step 6:
87 can be fit into 222 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 6272.0
The remainder is 48 after subtracting 174 from 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
87 goes into 480 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 6272.5
Subtract 435 from 480 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
450 divided by 87 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6272.55
Deduct 435 from 450 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 6272.55 with a remaining 0.015.
