Let's divide 486439 by 86
We're looking to find how many times 86 goes into 486439.

Let's proceed to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 86

Let's proceed to step 2:
When dividing 48 by 86, we get 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 86

On to step 3:
86 can be fit into 486 5 times, resulting in a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 430 from 486 and we're left with 56.
Include the next digit (4) from the dividend after 56, then repeat: 564 / 86

Going ahead to step 4:
86 can be fit into 564 6 times, resulting in a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Subtracting 516 from 564 leaves us with 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 86

On to step 5:
86 goes into 483 5 times with a remainder of 53.
The next digit of our result is 5. 
Result so far: 565.0
Deduct 430 from 483 and we're left with 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 86

On to step 6:
86 can be fit into 539 6 times, resulting in a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 5656.0
If we subtract 516 from 539, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
230 divided by 86 is 2 with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 5656.2
Subtract 172 from 230 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 5656.26
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 5656.267
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
380 divided by 86 is 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5656.2674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 5656.26744
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 5656.26744, and the remainder is 1.6e-05.
