We look at the division of 99666663 by 150 
We want to divide 99666663 by 150.

Step 1:
150 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 150

Let's proceed to step 2:
150 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Fetch the next digit (6) from the dividend, attach it to 99 and continue: 996 / 150

Step 3:
When dividing 996 by 150, we get 6 with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 96 after subtracting 900 from 996.
Include the next digit (6) from the dividend after 96, then repeat: 966 / 150

Step 4:
150 goes into 966 6 times with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 66 after subtracting 900 from 966.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 150

Step 5:
When dividing 666 by 150, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 664.0
The remainder is 66 after subtracting 600 from 666.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 150

Advancing to step 6:
150 goes into 666 4 times with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 6644.0
Subtract 600 from 666 to get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 150

Advancing to step 7:
If we divide 666 by 150, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 66444.0
If we subtract 600 from 666, we get 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 150

Step 8:
663 divided by 150 is 4 with a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 664444.0
If we take 600 away from 663, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
If we divide 630 by 150, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 664444.4
If we take 600 away from 630, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
150 goes into 300 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 664444.42
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 150, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 664444.42
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
If we divide 0 by 150, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 664444.42
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 664444.42 and a remainder of 0.0.
