If we divide 144 by 153, we get 0 and a remainder of 144.
The next digit of our result is 0. 
Result so far: 140.0
Subtracting 0 from 144 leaves us with 144.
Fetch the next digit (7) from the dividend, attach it to 144 and continue: 1447 / 153

Going ahead to step 6:
When dividing 1447 by 153, we get 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 1409.0
Deduct 1377 from 1447 and we're left with 70.
Append the next digit (1) from the dividend to 70 and continue with: 701 / 153

Going ahead to step 7:
153 goes into 701 4 times with a remainder of 89.
Use 4 as the next digit of our solution. 
Result so far: 14094.0
If we take 612 away from 701, we end up with 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 153

Going ahead to step 8:
If we divide 897 by 153, we get 5 and a remainder of 132.
The number 5 becomes the next digit in our result. 
Result so far: 140945.0
Subtract 765 from 897 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
The number 153 fits into 1320 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 140945.8
Deduct 1224 from 1320 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
The number 153 fits into 960 6 times, leaving a remainder of 42.
The next digit of our result is 6. 
Result so far: 140945.86
Subtracting 918 from 960 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
When dividing 420 by 153, we get 2 with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 140945.862
The remainder is 114 after subtracting 306 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 12:
When dividing 1140 by 153, we get 7 with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 140945.8627
The remainder is 69 after subtracting 1071 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
The number 153 fits into 690 4 times, leaving a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 140945.86274
If we take 612 away from 690, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 14:
780 divided by 153 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 140945.862745
Subtracting 765 from 780 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 15:
The number 153 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 140945.862745
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 16:
153 goes into 1500 9 times with a remainder of 123.
Record the quotient 9 as the next digit in the result. 
Result so far: 140945.86274509
If we take 1377 away from 1500, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

The quotient of the division is 140945.86274509, and the remainder is 1.23e-07.
