Let's divide 5986 by 66
We're looking to find how many times 66 goes into 5986.

On to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 66

Moving on to step 2:
66 goes into 59 0 times with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 66

On to step 3:
598 divided by 66 is 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 594 from 598 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 66

Advancing to step 4:
46 divided by 66 is 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtracting 0 from 46 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 5:
When dividing 460 by 66, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 90.6
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 6:
If we divide 640 by 66, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 90.69
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
460 divided by 66 is 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 90.696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
If we divide 640 by 66, we get 9 and a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 90.6969
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
When dividing 460 by 66, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 90.69696
If we subtract 396 from 460, 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.

Moving on to step 10:
640 divided by 66 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 90.696969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
When dividing 460 by 66, we get 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 90.6969696
Subtract 396 from 460 to 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.

Step 12:
66 can be fit into 640 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 90.69696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 90.69696969 with a remaining 4.6e-08.
