Let's divide 434985 by 87
Our goal is to divide 434985 by 87.

On to 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
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 87

Advancing to step 2:
When dividing 43 by 87, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 87

Going ahead to step 3:
When dividing 434 by 87, we get 4 with a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 348 from 434 to get 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 87

Advancing to step 4:
The number 87 fits into 869 9 times, leaving a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Deduct 783 from 869 and we're left with 86.
Append the next digit (8) from the dividend to 86 and continue with: 868 / 87

Going ahead to step 5:
When dividing 868 by 87, we get 9 with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 499.0
Subtracting 783 from 868 leaves us with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 87

Advancing to step 6:
The number 87 fits into 855 9 times, leaving a remainder of 72.
Put 9 as the next digit of the answer. 
Result so far: 4999.0
The remainder is 72 after subtracting 783 from 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
87 can be fit into 720 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 4999.8
Deduct 696 from 720 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
When dividing 240 by 87, we get 2 with a remainder of 66.
The next digit of our result is 2. 
Result so far: 4999.82
The remainder is 66 after subtracting 174 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
If we divide 660 by 87, we get 7 and a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 4999.827
The remainder is 51 after subtracting 609 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
510 divided by 87 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4999.8275
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
The number 87 fits into 750 8 times, leaving a remainder of 54.
The next digit of our result is 8. 
Result so far: 4999.82758
The remainder is 54 after subtracting 696 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
87 can be fit into 540 6 times, resulting in a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 4999.827586
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
The number 87 fits into 180 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 4999.8275862
Subtract 174 from 180 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 87 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4999.8275862
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 4999.8275862, with a leftover of 6e-08.
