87785315 ÷ 144 
We want to figure out the number of times 87785315 can be divided by 144.

Let's proceed to step 1:
When dividing 8 by 144, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 144

Going ahead to step 2:
144 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (7) from the dividend and append it to 87, then repeat: 877 / 144

On to step 3:
144 goes into 877 6 times with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 864 from 877, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 144

Step 4:
The number 144 fits into 138 0 times, leaving a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we take 0 away from 138, we end up with 138.
Fetch the next digit (5) from the dividend, attach it to 138 and continue: 1385 / 144

Going ahead to step 5:
144 goes into 1385 9 times with a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
If we take 1296 away from 1385, we end up with 89.
Append the next digit (3) from the dividend to 89 and continue with: 893 / 144

Moving on to step 6:
When dividing 893 by 144, we get 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 6096.0
Deduct 864 from 893 and we're left with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 144

Advancing to step 7:
The number 144 fits into 291 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 60962.0
The remainder is 3 after subtracting 288 from 291.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 144

Let's proceed to step 8:
When dividing 35 by 144, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 609620.0
If we take 0 away from 35, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
The number 144 fits into 350 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 609620.2
The remainder is 62 after subtracting 288 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
When dividing 620 by 144, we get 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 609620.24
If we take 576 away from 620, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
440 divided by 144 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 609620.243
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
144 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 609620.243
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 13:
144 can be fit into 800 5 times, resulting in a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 609620.24305
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
800 divided by 144 is 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 609620.243055
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 609620.243055 with a remaining 8e-06.
