66331571 divided by 144 
We want to divide 66331571 by 144.

Advancing to step 1:
If we divide 6 by 144, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 144

Let's proceed to step 2:
66 divided by 144 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 144

Step 3:
144 can be fit into 663 4 times, resulting in a remainder of 87.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 576 away from 663, we end up with 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 144

Moving on to step 4:
144 goes into 873 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtracting 864 from 873 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 144

Let's proceed to step 5:
If we divide 91 by 144, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 460.0
If we take 0 away from 91, we end up with 91.
Include the next digit (5) from the dividend after 91, then repeat: 915 / 144

Step 6:
144 can be fit into 915 6 times, resulting in a remainder of 51.
Record the quotient 6 as the next digit in the result. 
Result so far: 4606.0
Subtracting 864 from 915 leaves us with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 144

Going ahead to step 7:
144 can be fit into 517 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 46063.0
The remainder is 85 after subtracting 432 from 517.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 144

Step 8:
When dividing 851 by 144, we get 5 with a remainder of 131.
The next digit of our result is 5. 
Result so far: 460635.0
Subtracting 720 from 851 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 9:
144 goes into 1310 9 times with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 460635.9
The remainder is 14 after subtracting 1296 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
140 divided by 144 is 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 460635.9
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
The number 144 fits into 1400 9 times, leaving a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 460635.909
The remainder is 104 after subtracting 1296 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
The number 144 fits into 1040 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 460635.9097
Subtracting 1008 from 1040 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
144 can be fit into 320 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 460635.90972
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
144 can be fit into 320 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 460635.909722
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 460635.909722 with a remainder of 3.2e-06.
