We look at the division of 66634796 by 144 
We want to divide 66634796 by 144.

Moving on to step 1:
144 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 144

On to step 2:
The number 144 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (6) from the dividend, attach it to 66 and continue: 666 / 144

On to step 3:
If we divide 666 by 144, we get 4 and a remainder of 90.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 90 after subtracting 576 from 666.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 144

Going ahead to step 4:
144 can be fit into 903 6 times, resulting in a remainder of 39.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 864 from 903 and we're left with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 144

On to step 5:
394 divided by 144 is 2 with a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 462.0
If we take 288 away from 394, we end up with 106.
Include the next digit (7) from the dividend after 106, then repeat: 1067 / 144

Step 6:
If we divide 1067 by 144, we get 7 and a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 4627.0
If we take 1008 away from 1067, we end up with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 144

Let's proceed to step 7:
The number 144 fits into 599 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 46274.0
Deduct 576 from 599 and we're left with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 144

On to step 8:
When dividing 236 by 144, we get 1 with a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 462741.0
The remainder is 92 after subtracting 144 from 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
920 divided by 144 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 462741.6
Deduct 864 from 920 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
The number 144 fits into 560 3 times, leaving a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 462741.63
If we subtract 432 from 560, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
The number 144 fits into 1280 8 times, leaving a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 462741.638
If we take 1152 away from 1280, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
When dividing 1280 by 144, we get 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 462741.6388
Subtracting 1152 from 1280 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 462741.6388, with a leftover of 0.00128.
