We're dividing 25220789 by 484 
The aim is to understand the frequency of 484 in 25220789.

Step 1:
The number 484 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 484

Advancing to step 2:
484 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 484

Advancing to step 3:
The number 484 fits into 252 0 times, leaving a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 252 and we're left with 252.
Append the next digit (2) from the dividend to 252 and continue with: 2522 / 484

Moving on to step 4:
484 can be fit into 2522 5 times, resulting in a remainder of 102.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 2420 away from 2522, we end up with 102.
Bring next digit (0) of the dividend behind the 102 and repeat the process: 1020 / 484

Step 5:
484 goes into 1020 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 968 from 1020, we get 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 484

Let's proceed to step 6:
If we divide 527 by 484, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 521.0
Subtract 484 from 527 to get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 484

Moving on to step 7:
When dividing 438 by 484, we get 0 with a remainder of 438.
Write down 0 as next digit of the result. 
Result so far: 5210.0
The remainder is 438 after subtracting 0 from 438.
Take the next digit (9) from the dividend and append it to 438, then repeat: 4389 / 484

Moving on to step 8:
If we divide 4389 by 484, we get 9 and a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 52109.0
If we subtract 4356 from 4389, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 484 fits into 330 0 times, leaving a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 52109.0
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 10:
484 can be fit into 3300 6 times, resulting in a remainder of 396.
The number 6 becomes the next digit in our result. 
Result so far: 52109.06
Subtract 2904 from 3300 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 11:
484 goes into 3960 8 times with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 52109.068
If we subtract 3872 from 3960, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
484 goes into 880 1 times with a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 52109.0681
If we take 484 away from 880, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 13:
The number 484 fits into 3960 8 times, leaving a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 52109.06818
If we take 3872 away from 3960, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
When dividing 880 by 484, we get 1 with a remainder of 396.
Write down 1 as next digit of the result. 
Result so far: 52109.068181
Subtracting 484 from 880 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 15:
484 goes into 3960 8 times with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 52109.0681818
The remainder is 88 after subtracting 3872 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 16:
484 can be fit into 880 1 times, resulting in a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 52109.06818181
Subtract 484 from 880 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

After the division, we end up with 52109.06818181 and a remainder of 3.96e-07.
