We look at the division of 84668517 by 425 
The aim is to understand the frequency of 425 in 84668517.

Advancing to step 1:
If we divide 8 by 425, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 425

Moving on to step 2:
425 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 425

Moving on to step 3:
When dividing 846 by 425, we get 1 with a remainder of 421.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 425 from 846 to get 421.
Grab the next digit (6) from the dividend, add it to 421, then carry on: 4216 / 425

Let's proceed to step 4:
If we divide 4216 by 425, we get 9 and a remainder of 391.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 3825 from 4216, we get 391.
Take the next digit (8) from the dividend and append it to 391, then repeat: 3918 / 425

Going ahead to step 5:
425 can be fit into 3918 9 times, resulting in a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Subtract 3825 from 3918 to get 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 425

On to step 6:
If we divide 935 by 425, we get 2 and a remainder of 85.
Write down 2 as next digit of the result. 
Result so far: 1992.0
If we subtract 850 from 935, we get 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 425

Advancing to step 7:
The number 425 fits into 851 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 19922.0
Subtracting 850 from 851 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 425

Moving on to step 8:
17 divided by 425 is 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 199220.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
425 can be fit into 170 0 times, resulting in a remainder of 170.
The next digit of our result is 0. 
Result so far: 199220.0
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
1700 divided by 425 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 199220.04
The remainder is 0 after subtracting 1700 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
425 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 199220.04
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 425 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 199220.04
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 199220.04 with a remaining 0.0.
