We're dividing 447522 by 87 
The aim is to understand the frequency of 87 in 447522.

Advancing to step 1:
87 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 87

Moving on to step 2:
87 goes into 44 0 times with a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 87

Let's proceed to step 3:
When dividing 447 by 87, we get 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 435 from 447 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 87

Step 4:
87 can be fit into 125 1 times, resulting in a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 51.0
The remainder is 38 after subtracting 87 from 125.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 87

Advancing to step 5:
382 divided by 87 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
Deduct 348 from 382 and we're left with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 87

On to step 6:
87 goes into 342 3 times with a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 5143.0
If we take 261 away from 342, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 7:
810 divided by 87 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 5143.9
Subtracting 783 from 810 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
The number 87 fits into 270 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 5143.93
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
If we divide 90 by 87, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 5143.931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 87, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5143.931
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 87, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 5143.93103
If we take 261 away from 300, we end up 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 12:
The number 87 fits into 390 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 5143.931034
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
420 divided by 87 is 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 5143.9310344
If we take 348 away from 420, we end up with 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 quotient of the division is 5143.9310344, and the remainder is 7.2e-07.
