We're dividing 52251720 by 487 
The aim is to understand the frequency of 487 in 52251720.

Moving on to step 1:
487 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 487

On to step 2:
52 divided by 487 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 487

On to step 3:
If we divide 522 by 487, we get 1 and a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 487 from 522 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 487

Let's proceed to step 4:
If we divide 355 by 487, we get 0 and a remainder of 355.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 355 and we're left with 355.
Fetch the next digit (1) from the dividend, attach it to 355 and continue: 3551 / 487

Advancing to step 5:
The number 487 fits into 3551 7 times, leaving a remainder of 142.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtracting 3409 from 3551 leaves us with 142.
Bring next digit (7) of the dividend behind the 142 and repeat the process: 1427 / 487

Step 6:
The number 487 fits into 1427 2 times, leaving a remainder of 453.
The next digit of our result is 2. 
Result so far: 1072.0
Subtract 974 from 1427 to get 453.
Take the next digit (2) from the dividend and append it to 453, then repeat: 4532 / 487

Let's proceed to step 7:
If we divide 4532 by 487, we get 9 and a remainder of 149.
Use 9 as the next digit of our solution. 
Result so far: 10729.0
If we take 4383 away from 4532, we end up with 149.
Include the next digit (0) from the dividend after 149, then repeat: 1490 / 487

Moving on to step 8:
If we divide 1490 by 487, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 107293.0
If we subtract 1461 from 1490, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
487 can be fit into 290 0 times, resulting in a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 107293.0
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
When dividing 2900 by 487, we get 5 with a remainder of 465.
Use 5 as the next digit of our solution. 
Result so far: 107293.05
Subtracting 2435 from 2900 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 11:
The number 487 fits into 4650 9 times, leaving a remainder of 267.
Write down 9 as next digit of the result. 
Result so far: 107293.059
The remainder is 267 after subtracting 4383 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 12:
487 goes into 2670 5 times with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 107293.0595
Deduct 2435 from 2670 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 13:
487 goes into 2350 4 times with a remainder of 402.
Put 4 as the next digit of the answer. 
Result so far: 107293.05954
The remainder is 402 after subtracting 1948 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 14:
The number 487 fits into 4020 8 times, leaving a remainder of 124.
Record the quotient 8 as the next digit in the result. 
Result so far: 107293.059548
The remainder is 124 after subtracting 3896 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 15:
1240 divided by 487 is 2 with a remainder of 266.
Use 2 as the next digit of our solution. 
Result so far: 107293.0595482
Deduct 974 from 1240 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 16:
2660 divided by 487 is 5 with a remainder of 225.
The next digit of our result is 5. 
Result so far: 107293.05954825
If we take 2435 away from 2660, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 107293.05954825, and the remainder is 2.25e-07.
