465099 ÷ 87 
We want to figure out the number of times 465099 can be divided by 87.

Step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 87

Going ahead to step 2:
If we divide 46 by 87, we get 0 and a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 46 and we're left with 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 87

Going ahead to step 3:
If we divide 465 by 87, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 30 after subtracting 435 from 465.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 87

Step 4:
When dividing 300 by 87, we get 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 39 after subtracting 261 from 300.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 87

Moving on to step 5:
If we divide 399 by 87, we get 4 and a remainder of 51.
Record the quotient 4 as the next digit in the result. 
Result so far: 534.0
Subtract 348 from 399 to get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 87

Moving on to step 6:
87 can be fit into 519 5 times, resulting in a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 5345.0
The remainder is 84 after subtracting 435 from 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
87 can be fit into 840 9 times, resulting in a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 5345.9
Subtract 783 from 840 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 8:
The number 87 fits into 570 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 5345.96
The remainder is 48 after subtracting 522 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
When dividing 480 by 87, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 5345.965
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 87, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5345.9655
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 5345.9655, with a leftover of 0.00015.
