Let's divide 899642 by 66
We're looking to find how many times 66 goes into 899642.

Step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 66

Advancing to step 2:
66 goes into 89 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 66 from 89 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 66

Moving on to step 3:
66 can be fit into 239 3 times, resulting in a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 198 from 239 and we're left with 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 66

Step 4:
66 goes into 416 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtract 396 from 416 to get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 66

Going ahead to step 5:
204 divided by 66 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1363.0
Deduct 198 from 204 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 66

On to step 6:
If we divide 62 by 66, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 13630.0
Deduct 0 from 62 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
If we divide 620 by 66, we get 9 and a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 13630.9
Deduct 594 from 620 and we're left 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 8:
If we divide 260 by 66, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 13630.93
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
66 goes into 620 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 13630.939
Subtract 594 from 620 to get 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 10:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The next digit of our result is 3. 
Result so far: 13630.9393
If we subtract 198 from 260, 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 11:
When dividing 620 by 66, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 13630.93939
Subtracting 594 from 620 leaves us 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.

Let's proceed to step 12:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 13630.939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
When dividing 620 by 66, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 13630.9393939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 13630.93939393
Subtract 198 from 260 to 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.

Our division results in 13630.93939393 with a remaining 6.2e-08.
