Let's divide 486436 by 87
We want to divide 486436 by 87.

Advancing to step 1:
If we divide 4 by 87, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 87

On to step 2:
If we divide 48 by 87, we get 0 and a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 87

Let's proceed to step 3:
The number 87 fits into 486 5 times, leaving a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 435 from 486, we get 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 87

On to step 4:
87 goes into 514 5 times with a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 79 after subtracting 435 from 514.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 87

Moving on to step 5:
87 goes into 793 9 times with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 559.0
Deduct 783 from 793 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 87

Moving on to step 6:
106 divided by 87 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 5591.0
Deduct 87 from 106 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
87 can be fit into 190 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 5591.2
The remainder is 16 after subtracting 174 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
87 goes into 160 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 5591.21
If we take 87 away from 160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
If we divide 730 by 87, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 5591.218
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
When dividing 340 by 87, we get 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 5591.2183
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
87 can be fit into 790 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 5591.21839
The remainder is 7 after subtracting 783 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
87 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 5591.21839
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 13:
The number 87 fits into 700 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 5591.2183908
If we take 696 away from 700, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
87 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5591.2183908
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 5591.2183908 with a remaining 4e-08.
