We look at the division of 75979039 by 144 
Let's see how many times 144 fits into 75979039.

Step 1:
If we divide 7 by 144, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 144

Let's proceed to step 2:
The number 144 fits into 75 0 times, leaving a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Fetch the next digit (9) from the dividend, attach it to 75 and continue: 759 / 144

On to step 3:
759 divided by 144 is 5 with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 720 from 759 to get 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 144

Moving on to step 4:
144 goes into 397 2 times with a remainder of 109.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 288 away from 397, we end up with 109.
Include the next digit (9) from the dividend after 109, then repeat: 1099 / 144

Moving on to step 5:
144 can be fit into 1099 7 times, resulting in a remainder of 91.
Use 7 as the next digit of our solution. 
Result so far: 527.0
If we subtract 1008 from 1099, we get 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 144

On to step 6:
If we divide 910 by 144, we get 6 and a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 5276.0
Deduct 864 from 910 and we're left with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 144

Moving on to step 7:
144 can be fit into 463 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 52763.0
The remainder is 31 after subtracting 432 from 463.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 144

On to step 8:
If we divide 319 by 144, we get 2 and a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 527632.0
The remainder is 31 after subtracting 288 from 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
If we divide 310 by 144, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 527632.2
Subtract 288 from 310 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 144, we get 1 and a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 527632.21
Subtract 144 from 220 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
144 goes into 760 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 527632.215
If we take 720 away from 760, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
144 can be fit into 400 2 times, resulting in a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 527632.2152
The remainder is 112 after subtracting 288 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
If we divide 1120 by 144, we get 7 and a remainder of 112.
Record the quotient 7 as the next digit in the result. 
Result so far: 527632.21527
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
1120 divided by 144 is 7 with a remainder of 112.
Write down 7 as next digit of the result. 
Result so far: 527632.215277
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 527632.215277 and a remainder of 1.12e-05.
