830723 ÷ 87 
The aim is to understand the frequency of 87 in 830723.

On to step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 87

Step 2:
The number 87 fits into 83 0 times, leaving a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 87

On to step 3:
830 divided by 87 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 783 from 830 leaves us with 47.
Grab the next digit (7) from the dividend, add it to 47, then carry on: 477 / 87

Moving on to step 4:
87 can be fit into 477 5 times, resulting in a remainder of 42.
The next digit of our result is 5. 
Result so far: 95.0
Subtracting 435 from 477 leaves us with 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 87

Let's proceed to step 5:
When dividing 422 by 87, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 954.0
Deduct 348 from 422 and we're left with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 87

Going ahead to step 6:
If we divide 743 by 87, we get 8 and a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 9548.0
Subtracting 696 from 743 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
470 divided by 87 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9548.5
If we subtract 435 from 470, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
87 goes into 350 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 9548.54
If we subtract 348 from 350, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
When dividing 20 by 87, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 9548.54
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
200 divided by 87 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 9548.5402
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
87 can be fit into 260 2 times, resulting in a remainder of 86.
The next digit of our result is 2. 
Result so far: 9548.54022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 9548.54022, and the remainder is 8.6e-05.
