Let's divide 663744 by 87
We want to figure out the number of times 663744 can be divided by 87.

Advancing to step 1:
6 divided by 87 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 87

Moving on to step 2:
87 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (3) from the dividend, add it to 66, then carry on: 663 / 87

Going ahead to step 3:
87 can be fit into 663 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 609 from 663 and we're left with 54.
Fetch the next digit (7) from the dividend, attach it to 54 and continue: 547 / 87

Let's proceed to step 4:
547 divided by 87 is 6 with a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 25 after subtracting 522 from 547.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 87

Going ahead to step 5:
87 can be fit into 254 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 762.0
Subtract 174 from 254 to get 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 87

On to step 6:
When dividing 804 by 87, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7629.0
Deduct 783 from 804 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
87 can be fit into 210 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 7629.2
Subtract 174 from 210 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
360 divided by 87 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 7629.24
If we subtract 348 from 360, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
87 can be fit into 120 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 7629.241
If we subtract 87 from 120, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
87 goes into 330 3 times with a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 7629.2413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 11:
If we divide 690 by 87, we get 7 and a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 7629.24137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
The number 87 fits into 810 9 times, leaving a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 7629.241379
The remainder is 27 after subtracting 783 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 13:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 7629.2413793
If we take 261 away from 270, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
If we divide 90 by 87, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 7629.24137931
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 7629.24137931 with a remainder of 3e-09.
