987643 ÷ 66 
Let's see how many times 66 fits into 987643.

Let's proceed to step 1:
9 divided by 66 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 66

On to step 2:
If we divide 98 by 66, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 66 from 98 leaves us with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 66

Let's proceed to step 3:
If we divide 327 by 66, we get 4 and a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 63 after subtracting 264 from 327.
Bring next digit (6) of the dividend behind the 63 and repeat the process: 636 / 66

Going ahead to step 4:
If we divide 636 by 66, we get 9 and a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 149.0
The remainder is 42 after subtracting 594 from 636.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 66

Moving on to step 5:
When dividing 424 by 66, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1496.0
The remainder is 28 after subtracting 396 from 424.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 66

Moving on to step 6:
The number 66 fits into 283 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 14964.0
If we take 264 away from 283, we end up 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.

Step 7:
66 goes into 190 2 times with a remainder of 58.
The next digit of our result is 2. 
Result so far: 14964.2
If we take 132 away from 190, we end up with 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:
If we divide 580 by 66, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 14964.28
Deduct 528 from 580 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 14964.287
If we subtract 462 from 520, we 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.

Let's proceed to step 10:
When dividing 580 by 66, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 14964.2878
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 14964.28787
If we take 462 away from 520, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
66 can be fit into 580 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 14964.287878
If we take 528 away from 580, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
520 divided by 66 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 14964.2878787
If we take 462 away from 520, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
If we divide 580 by 66, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 14964.28787878
The remainder is 52 after subtracting 528 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 14964.28787878 with a balance of 5.2e-08.
