We divide 85429890 by 510
The aim is to understand the frequency of 510 in 85429890.

Advancing to step 1:
The number 510 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 510

Step 2:
510 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 510

Let's proceed to step 3:
When dividing 854 by 510, we get 1 with a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 510 from 854, we get 344.
Include the next digit (2) from the dividend after 344, then repeat: 3442 / 510

Let's proceed to step 4:
510 goes into 3442 6 times with a remainder of 382.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 3060 from 3442 and we're left with 382.
Fetch the next digit (9) from the dividend, attach it to 382 and continue: 3829 / 510

Step 5:
3829 divided by 510 is 7 with a remainder of 259.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
If we take 3570 away from 3829, we end up with 259.
Bring next digit (8) of the dividend behind the 259 and repeat the process: 2598 / 510

On to step 6:
The number 510 fits into 2598 5 times, leaving a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 1675.0
Deduct 2550 from 2598 and we're left with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 510

Moving on to step 7:
510 can be fit into 489 0 times, resulting in a remainder of 489.
The number 0 becomes the next digit in our result. 
Result so far: 16750.0
If we take 0 away from 489, we end up with 489.
Append the next digit (0) from the dividend to 489 and continue with: 4890 / 510

Going ahead to step 8:
The number 510 fits into 4890 9 times, leaving a remainder of 300.
The number 9 becomes the next digit in our result. 
Result so far: 167509.0
If we take 4590 away from 4890, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 9:
When dividing 3000 by 510, we get 5 with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 167509.5
The remainder is 450 after subtracting 2550 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 10:
4500 divided by 510 is 8 with a remainder of 420.
The next digit of our result is 8. 
Result so far: 167509.58
The remainder is 420 after subtracting 4080 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
When dividing 4200 by 510, we get 8 with a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 167509.588
Deduct 4080 from 4200 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 167509.588 and a remainder of 0.012.
