We're dividing 300697 by 87 
The aim is to understand the frequency of 87 in 300697.

Let's proceed to step 1:
The number 87 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 87

On to step 2:
If we divide 30 by 87, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 87

On to step 3:
The number 87 fits into 300 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 261 from 300 and we're left with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 87

On to step 4:
87 goes into 396 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 348 from 396, we get 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 87

On to step 5:
The number 87 fits into 489 5 times, leaving a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
Subtract 435 from 489 to get 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 87

Moving on to step 6:
87 can be fit into 547 6 times, resulting in a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 3456.0
If we take 522 away from 547, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
250 divided by 87 is 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 3456.2
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: 3456.28
Subtract 696 from 760 to 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.

Advancing to step 9:
The number 87 fits into 640 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 3456.287
Deduct 609 from 640 and we're left 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.

Advancing to step 10:
When dividing 310 by 87, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 3456.2873
If we subtract 261 from 310, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
87 can be fit into 490 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 3456.28735
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.

On to step 12:
87 can be fit into 550 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 3456.287356
The remainder is 28 after subtracting 522 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
If we divide 280 by 87, we get 3 and a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3456.2873563
Subtracting 261 from 280 leaves us 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.

Advancing to step 14:
190 divided by 87 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 3456.28735632
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.

After the division, we end up with 3456.28735632 and a remainder of 1.6e-08.
