We look at the division of 64095509 by 851 
The aim is to understand the frequency of 851 in 64095509.

Step 1:
The number 851 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 851

Moving on to step 2:
If we divide 64 by 851, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 851

Going ahead to step 3:
If we divide 640 by 851, we get 0 and a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 640 leaves us with 640.
Include the next digit (9) from the dividend after 640, then repeat: 6409 / 851

Let's proceed to step 4:
When dividing 6409 by 851, we get 7 with a remainder of 452.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5957 from 6409, we get 452.
Bring next digit (5) of the dividend behind the 452 and repeat the process: 4525 / 851

Step 5:
If we divide 4525 by 851, we get 5 and a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we take 4255 away from 4525, we end up with 270.
Bring next digit (5) of the dividend behind the 270 and repeat the process: 2705 / 851

Step 6:
851 can be fit into 2705 3 times, resulting in a remainder of 152.
Use 3 as the next digit of our solution. 
Result so far: 753.0
Subtracting 2553 from 2705 leaves us with 152.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 851

Moving on to step 7:
851 goes into 1520 1 times with a remainder of 669.
Record the quotient 1 as the next digit in the result. 
Result so far: 7531.0
If we take 851 away from 1520, we end up with 669.
Take the next digit (9) from the dividend and append it to 669, then repeat: 6699 / 851

Step 8:
The number 851 fits into 6699 7 times, leaving a remainder of 742.
Write down 7 as next digit of the result. 
Result so far: 75317.0
Deduct 5957 from 6699 and we're left with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Advancing to step 9:
If we divide 7420 by 851, we get 8 and a remainder of 612.
Write down 8 as next digit of the result. 
Result so far: 75317.8
If we subtract 6808 from 7420, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Let's proceed to step 10:
851 goes into 6120 7 times with a remainder of 163.
Record the quotient 7 as the next digit in the result. 
Result so far: 75317.87
Subtracting 5957 from 6120 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 11:
The number 851 fits into 1630 1 times, leaving a remainder of 779.
Put 1 as the next digit of the answer. 
Result so far: 75317.871
If we take 851 away from 1630, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 12:
851 can be fit into 7790 9 times, resulting in a remainder of 131.
The next digit of our result is 9. 
Result so far: 75317.8719
The remainder is 131 after subtracting 7659 from 7790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 13:
851 can be fit into 1310 1 times, resulting in a remainder of 459.
Write down 1 as next digit of the result. 
Result so far: 75317.87191
If we take 851 away from 1310, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 14:
If we divide 4590 by 851, we get 5 and a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 75317.871915
Subtracting 4255 from 4590 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 15:
851 goes into 3350 3 times with a remainder of 797.
The number 3 becomes the next digit in our result. 
Result so far: 75317.8719153
If we subtract 2553 from 3350, we get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Going ahead to step 16:
851 goes into 7970 9 times with a remainder of 311.
Write down 9 as next digit of the result. 
Result so far: 75317.87191539
Deduct 7659 from 7970 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

In conclusion, the division gives 75317.87191539 with a balance of 3.11e-07.
