We're dividing 87761740 by 144 
Let's see how many times 144 fits into 87761740.

Going ahead to step 1:
The number 144 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 144

Moving on to step 2:
If we divide 87 by 144, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Bring next digit (7) of the dividend behind the 87 and repeat the process: 877 / 144

Moving on to step 3:
144 can be fit into 877 6 times, resulting in a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 864 from 877 and we're left with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 144

Step 4:
The number 144 fits into 136 0 times, leaving a remainder of 136.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we take 0 away from 136, we end up with 136.
Bring next digit (1) of the dividend behind the 136 and repeat the process: 1361 / 144

Advancing to step 5:
1361 divided by 144 is 9 with a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
Subtract 1296 from 1361 to get 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 144

Advancing to step 6:
657 divided by 144 is 4 with a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 6094.0
Subtract 576 from 657 to get 81.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 144

Advancing to step 7:
144 goes into 814 5 times with a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 60945.0
If we take 720 away from 814, we end up with 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 144

Going ahead to step 8:
144 can be fit into 940 6 times, resulting in a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 609456.0
Subtracting 864 from 940 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
If we divide 760 by 144, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 609456.5
Subtracting 720 from 760 leaves us 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.

Let's proceed to step 10:
400 divided by 144 is 2 with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 609456.52
If we subtract 288 from 400, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
If we divide 1120 by 144, we get 7 and a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 609456.527
Deduct 1008 from 1120 and we're left 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.

Let's proceed to step 12:
144 can be fit into 1120 7 times, resulting in a remainder of 112.
The next digit of our result is 7. 
Result so far: 609456.5277
If we subtract 1008 from 1120, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 609456.5277, with a leftover of 0.00112.
