We're dividing 763273 by 87 
The aim is to understand the frequency of 87 in 763273.

On to step 1:
87 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 87

On to step 2:
When dividing 76 by 87, we get 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 87

Step 3:
The number 87 fits into 763 8 times, leaving a remainder of 67.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 696 from 763 and we're left with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 87

Step 4:
87 can be fit into 672 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 609 from 672 leaves us with 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 87

Let's proceed to step 5:
The number 87 fits into 637 7 times, leaving a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 877.0
Deduct 609 from 637 and we're left with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 87

Going ahead to step 6:
87 can be fit into 283 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 8773.0
If we take 261 away from 283, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
220 divided by 87 is 2 with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 8773.2
Deduct 174 from 220 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
87 can be fit into 460 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8773.25
Subtracting 435 from 460 leaves us 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.

Advancing to step 9:
When dividing 250 by 87, we get 2 with a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 8773.252
The remainder is 76 after subtracting 174 from 250.
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 10:
760 divided by 87 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 8773.2528
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.

Step 11:
The number 87 fits into 640 7 times, leaving a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 8773.25287
Subtracting 609 from 640 leaves us 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.

Let's proceed to step 12:
If we divide 310 by 87, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 8773.252873
Subtracting 261 from 310 leaves us 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.

Going ahead to step 13:
87 can be fit into 490 5 times, resulting in a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 8773.2528735
Subtracting 435 from 490 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
87 can be fit into 550 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 8773.25287356
Deduct 522 from 550 and we're left 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.

The final result is 8773.25287356 with a remainder of 2.8e-08.
