We look at the division of 76623937 by 144 
We want to divide 76623937 by 144.

Advancing to step 1:
144 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 144

Going ahead to step 2:
76 divided by 144 is 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 144

Advancing to step 3:
When dividing 766 by 144, we get 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 46 after subtracting 720 from 766.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 144

On to step 4:
144 goes into 462 3 times with a remainder of 30.
The next digit of our result is 3. 
Result so far: 53.0
Subtract 432 from 462 to get 30.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 144

Going ahead to step 5:
When dividing 303 by 144, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 532.0
The remainder is 15 after subtracting 288 from 303.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 144

Step 6:
144 goes into 159 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 5321.0
Deduct 144 from 159 and we're left with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 144

Going ahead to step 7:
144 goes into 153 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 53211.0
Deduct 144 from 153 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 144

Advancing to step 8:
144 can be fit into 97 0 times, resulting in a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 532110.0
If we subtract 0 from 97, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
970 divided by 144 is 6 with a remainder of 106.
The number 6 becomes the next digit in our result. 
Result so far: 532110.6
Deduct 864 from 970 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
The number 144 fits into 1060 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 532110.67
If we subtract 1008 from 1060, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 144, we get 3 with a remainder of 88.
The next digit of our result is 3. 
Result so far: 532110.673
Subtracting 432 from 520 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
144 can be fit into 880 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 532110.6736
If we subtract 864 from 880, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
160 divided by 144 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 532110.67361
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
160 divided by 144 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 532110.673611
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 532110.673611 with a remainder of 1.6e-06.
