Let's divide 753415 by 87
Let's see how many times 87 fits into 753415.

Moving on to step 1:
87 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 87

Let's proceed to step 2:
87 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 87

Step 3:
87 can be fit into 753 8 times, resulting in a remainder of 57.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 696 from 753 leaves us with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 87

Let's proceed to step 4:
574 divided by 87 is 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 86.0
Subtract 522 from 574 to get 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 87

Step 5:
521 divided by 87 is 5 with a remainder of 86.
Use 5 as the next digit of our solution. 
Result so far: 865.0
If we subtract 435 from 521, we get 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 87

On to step 6:
If we divide 865 by 87, we get 9 and a remainder of 82.
The next digit of our result is 9. 
Result so far: 8659.0
Deduct 783 from 865 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 7:
87 can be fit into 820 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 8659.9
Deduct 783 from 820 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
370 divided by 87 is 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 8659.94
Deduct 348 from 370 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
220 divided by 87 is 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 8659.942
If we take 174 away from 220, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
When dividing 460 by 87, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8659.9425
If we subtract 435 from 460, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
The number 87 fits into 250 2 times, leaving a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 8659.94252
If we subtract 174 from 250, we 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 12:
87 goes into 760 8 times with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 8659.942528
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
When dividing 640 by 87, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 8659.9425287
If we take 609 away from 640, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 14:
When dividing 310 by 87, we get 3 with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 8659.94252873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 8659.94252873, with a leftover of 4.9e-08.
