75135 divided by 87 
We want to figure out the number of times 75135 can be divided by 87.

Let's proceed to step 1:
If we divide 7 by 87, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 87

On to step 2:
If we divide 75 by 87, we get 0 and 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 (1) from the dividend, attach it to 75 and continue: 751 / 87

Moving on to step 3:
When dividing 751 by 87, we get 8 with a remainder of 55.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 696 from 751 to get 55.
Bring next digit (3) of the dividend behind the 55 and repeat the process: 553 / 87

Advancing to step 4:
The number 87 fits into 553 6 times, leaving a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtract 522 from 553 to get 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 87

Advancing to step 5:
315 divided by 87 is 3 with a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
Deduct 261 from 315 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 6:
If we divide 540 by 87, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 863.6
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
180 divided by 87 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 863.62
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 87 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 863.62
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 87 fits into 600 6 times, leaving a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 863.6206
Subtract 522 from 600 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 10:
780 divided by 87 is 8 with a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 863.62068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 11:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 863.620689
Deduct 783 from 840 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 12:
When dividing 570 by 87, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 863.6206896
Subtracting 522 from 570 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
87 can be fit into 480 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 863.62068965
Subtract 435 from 480 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 863.62068965, with a leftover of 4.5e-08.
