We look at the division of 85098507 by 424 
The aim is to understand the frequency of 424 in 85098507.

Going ahead to step 1:
8 divided by 424 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 424

On to step 2:
424 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 424

Let's proceed to step 3:
When dividing 850 by 424, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 848 from 850, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 424

On to step 4:
424 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 424

Moving on to step 5:
When dividing 298 by 424, we get 0 with a remainder of 298.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Deduct 0 from 298 and we're left with 298.
Bring next digit (5) of the dividend behind the 298 and repeat the process: 2985 / 424

Step 6:
424 goes into 2985 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2007.0
Subtracting 2968 from 2985 leaves us with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 424

On to step 7:
The number 424 fits into 170 0 times, leaving a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 20070.0
The remainder is 170 after subtracting 0 from 170.
Append the next digit (7) from the dividend to 170 and continue with: 1707 / 424

Step 8:
424 goes into 1707 4 times with a remainder of 11.
The next digit of our result is 4. 
Result so far: 200704.0
Subtracting 1696 from 1707 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
The number 424 fits into 110 0 times, leaving a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 200704.0
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
1100 divided by 424 is 2 with a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 200704.02
Deduct 848 from 1100 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 11:
424 can be fit into 2520 5 times, resulting in a remainder of 400.
The next digit of our result is 5. 
Result so far: 200704.025
If we subtract 2120 from 2520, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 424, we get 9 with a remainder of 184.
Record the quotient 9 as the next digit in the result. 
Result so far: 200704.0259
If we take 3816 away from 4000, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 13:
424 goes into 1840 4 times with a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 200704.02594
If we subtract 1696 from 1840, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
424 can be fit into 1440 3 times, resulting in a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 200704.025943
If we subtract 1272 from 1440, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 15:
When dividing 1680 by 424, we get 3 with a remainder of 408.
Record the quotient 3 as the next digit in the result. 
Result so far: 200704.0259433
Deduct 1272 from 1680 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 200704.0259433, with a leftover of 4.08e-06.
