We're dividing 663745 by 87 
We want to divide 663745 by 87.

Advancing to step 1:
6 divided by 87 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 87

Let's proceed to step 2:
The number 87 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 87

Going ahead to step 3:
If we divide 663 by 87, we get 7 and a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 609 away from 663, we end up with 54.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 87

Step 4:
If we divide 547 by 87, we get 6 and a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 76.0
If we take 522 away from 547, we end up with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 87

Let's proceed to step 5:
87 can be fit into 254 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 762.0
If we subtract 174 from 254, we get 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 87

Advancing to step 6:
87 goes into 805 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 7629.0
Deduct 783 from 805 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 7:
87 can be fit into 220 2 times, resulting in a remainder of 46.
The next digit of our result is 2. 
Result so far: 7629.2
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
460 divided by 87 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7629.25
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.

Moving on to step 9:
87 goes into 250 2 times with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 7629.252
If we take 174 away from 250, we end up 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.

Let's proceed to step 10:
87 goes into 760 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 7629.2528
If we subtract 696 from 760, we 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.

Moving on to step 11:
87 goes into 640 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7629.25287
The remainder is 31 after subtracting 609 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
87 goes into 310 3 times with a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 7629.252873
The remainder is 49 after subtracting 261 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
87 can be fit into 490 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 7629.2528735
If we take 435 away from 490, we end up 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.

Step 14:
When dividing 550 by 87, we get 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 7629.25287356
If we subtract 522 from 550, we 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.

After the division, we end up with 7629.25287356 and a remainder of 2.8e-08.
