Let's divide 661317 by 87
We want to figure out the number of times 661317 can be divided by 87.

Let's proceed 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
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 87

Step 2:
87 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 87

Advancing to step 3:
87 can be fit into 661 7 times, resulting in a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 609 from 661 and we're left with 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 87

Moving on to step 4:
87 can be fit into 523 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 522 from 523 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 87

On to step 5:
The number 87 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 760.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 87

Step 6:
The number 87 fits into 117 1 times, leaving a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 7601.0
Subtracting 87 from 117 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
87 goes into 300 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 7601.3
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
87 goes into 390 4 times with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 7601.34
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
When dividing 420 by 87, we get 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 7601.344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 7601.344 with a remainder of 0.0072.
