66278609 ÷ 150 
We're looking to find how many times 150 goes into 66278609.

Let's proceed to step 1:
The number 150 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 150

Step 2:
150 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 150

Going ahead to step 3:
150 can be fit into 662 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 600 from 662 and we're left with 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 150

Advancing to step 4:
The number 150 fits into 627 4 times, leaving a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 27 after subtracting 600 from 627.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 150

Going ahead to step 5:
If we divide 278 by 150, we get 1 and a remainder of 128.
Record the quotient 1 as the next digit in the result. 
Result so far: 441.0
Subtract 150 from 278 to get 128.
Fetch the next digit (6) from the dividend, attach it to 128 and continue: 1286 / 150

Let's proceed to step 6:
The number 150 fits into 1286 8 times, leaving a remainder of 86.
The next digit of our result is 8. 
Result so far: 4418.0
If we subtract 1200 from 1286, we get 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 150

Advancing to step 7:
If we divide 860 by 150, we get 5 and a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 44185.0
The remainder is 110 after subtracting 750 from 860.
Take the next digit (9) from the dividend and append it to 110, then repeat: 1109 / 150

Moving on to step 8:
150 goes into 1109 7 times with a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 441857.0
If we take 1050 away from 1109, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
150 can be fit into 590 3 times, resulting in a remainder of 140.
The number 3 becomes the next digit in our result. 
Result so far: 441857.3
The remainder is 140 after subtracting 450 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
1400 divided by 150 is 9 with a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 441857.39
Subtracting 1350 from 1400 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.

Step 11:
When dividing 500 by 150, we get 3 with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 441857.393
Deduct 450 from 500 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.

Step 12:
When dividing 500 by 150, we get 3 with a remainder of 50.
The next digit of our result is 3. 
Result so far: 441857.3933
If we take 450 away from 500, 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.

The quotient of the division is 441857.3933, and the remainder is 0.0005.
