477991 ÷ 86 
Our goal is to divide 477991 by 86.

Step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 86

On to step 2:
86 can be fit into 47 0 times, resulting in a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 86

On to step 3:
477 divided by 86 is 5 with a remainder of 47.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 430 from 477, we get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 86

Going ahead to step 4:
86 goes into 479 5 times with a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 55.0
Deduct 430 from 479 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 86

Step 5:
86 can be fit into 499 5 times, resulting in a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 555.0
If we subtract 430 from 499, we get 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 86

Moving on to step 6:
When dividing 691 by 86, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 5558.0
If we take 688 away from 691, we end up 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 7:
If we divide 30 by 86, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 5558.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 5558.03
Deduct 258 from 300 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.

Let's proceed to step 9:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 5558.034
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
760 divided by 86 is 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 5558.0348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 5558.03488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 5558.03488 with a balance of 3.2e-05.
