703645 ÷ 87 
Let's see how many times 87 fits into 703645.

Going ahead to step 1:
The number 87 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 87

Moving on to step 2:
When dividing 70 by 87, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Grab the next digit (3) from the dividend, add it to 70, then carry on: 703 / 87

Let's proceed to step 3:
87 goes into 703 8 times with a remainder of 7.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 696 from 703, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 87

Let's proceed to step 4:
87 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 87

On to step 5:
87 goes into 764 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 808.0
Deduct 696 from 764 and we're left with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 87

Advancing to step 6:
87 goes into 685 7 times with a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 8087.0
The remainder is 76 after subtracting 609 from 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 7:
If we divide 760 by 87, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 8087.8
Subtract 696 from 760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
87 can be fit into 640 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 8087.87
If we subtract 609 from 640, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
The number 87 fits into 310 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 8087.873
If we take 261 away from 310, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
87 goes into 490 5 times with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 8087.8735
Subtracting 435 from 490 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
If we divide 550 by 87, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 8087.87356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
87 can be fit into 280 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 8087.873563
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
87 can be fit into 190 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 8087.8735632
If we take 174 away from 190, we end up 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:
87 can be fit into 160 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 8087.87356321
Subtract 87 from 160 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final result is 8087.87356321 with a remainder of 7.3e-08.
