985909 ÷ 87 
The aim is to understand the frequency of 87 in 985909.

Let's proceed to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 87

Let's proceed to step 2:
87 goes into 98 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 87 from 98 to get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 87

Step 3:
The number 87 fits into 115 1 times, leaving a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 87 from 115 leaves us with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 87

Going ahead to step 4:
When dividing 289 by 87, we get 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtracting 261 from 289 leaves us with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 87

Let's proceed to step 5:
If we divide 280 by 87, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 1133.0
Subtracting 261 from 280 leaves us with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 87

Going ahead to step 6:
The number 87 fits into 199 2 times, leaving a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 11332.0
If we subtract 174 from 199, 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.

Step 7:
87 goes into 250 2 times with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 11332.2
Deduct 174 from 250 and we're left 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.

On to step 8:
If we divide 760 by 87, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 11332.28
The remainder is 64 after subtracting 696 from 760.
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 9:
87 can be fit into 640 7 times, resulting in a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11332.287
If we take 609 away from 640, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
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: 11332.2873
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.

On to step 11:
490 divided by 87 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 11332.28735
Subtract 435 from 490 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 12:
550 divided by 87 is 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 11332.287356
Subtracting 522 from 550 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
87 can be fit into 280 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 11332.2873563
Deduct 261 from 280 and we're left 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.

On to step 14:
87 goes into 190 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11332.28735632
If we subtract 174 from 190, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 11332.28735632 with a remainder of 1.6e-08.
