We look at the division of 991622 by 66 
We're looking to find how many times 66 goes into 991622.

Advancing to step 1:
66 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 66

Moving on to step 2:
66 can be fit into 99 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 66 away from 99, we end up with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 66

Going ahead to step 3:
The number 66 fits into 331 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 330 away from 331, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 66

Going ahead to step 4:
If we divide 16 by 66, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 150.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 66

On to step 5:
When dividing 162 by 66, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 1502.0
The remainder is 30 after subtracting 132 from 162.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 66

Step 6:
66 goes into 302 4 times with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 15024.0
Subtract 264 from 302 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
When dividing 380 by 66, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 15024.5
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
If we divide 500 by 66, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 15024.57
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
380 divided by 66 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 15024.575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
If we divide 500 by 66, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 15024.5757
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 15024.57575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 15024.575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 15024.5757575
If we take 330 away from 380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
When dividing 500 by 66, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 15024.57575757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 15024.57575757, with a leftover of 3.8e-08.
