We're dividing 489966 by 87 
We want to figure out the number of times 489966 can be divided by 87.

Going ahead to step 1:
4 divided by 87 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 87

On to step 2:
48 divided by 87 is 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 87

Advancing to step 3:
489 divided by 87 is 5 with a remainder of 54.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 435 from 489 to get 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 87

Advancing to step 4:
549 divided by 87 is 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 522 from 549 to get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 87

Moving on to step 5:
87 goes into 276 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 563.0
If we subtract 261 from 276, we get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 87

Let's proceed to step 6:
If we divide 156 by 87, we get 1 and a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 5631.0
Deduct 87 from 156 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
If we divide 690 by 87, we get 7 and a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 5631.7
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
The number 87 fits into 810 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 5631.79
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 5631.793
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
The number 87 fits into 90 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 5631.7931
Deduct 87 from 90 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
If we divide 30 by 87, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5631.7931
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 87, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 5631.793103
Subtracting 261 from 300 leaves us with 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 13:
87 can be fit into 390 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 5631.7931034
Deduct 348 from 390 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 5631.79310344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 5631.79310344, with a leftover of 7.2e-08.
