489458 ÷ 86 
We want to figure out the number of times 489458 can be divided by 86.

Going ahead to step 1:
4 divided by 86 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 86

On to step 2:
86 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 86

Going ahead to step 3:
When dividing 489 by 86, we get 5 with a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 430 from 489, we get 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 86

Advancing to step 4:
86 goes into 594 6 times with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 516 from 594 to get 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 86

On to step 5:
The number 86 fits into 785 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 569.0
Subtracting 774 from 785 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 86

Moving on to step 6:
86 can be fit into 118 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 5691.0
If we subtract 86 from 118, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
The number 86 fits into 320 3 times, leaving a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 5691.3
If we subtract 258 from 320, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
620 divided by 86 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 5691.37
The remainder is 18 after subtracting 602 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
The number 86 fits into 180 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 5691.372
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 86, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 5691.372
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 86 fits into 800 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 5691.37209
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
The number 86 fits into 260 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 5691.372093
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
If we divide 20 by 86, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5691.372093
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
200 divided by 86 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 5691.37209302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 5691.37209302, and the remainder is 2.8e-08.
