We divide 85051607 by 309
The aim is to understand the frequency of 309 in 85051607.

On to step 1:
309 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 309

On to step 2:
When dividing 85 by 309, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 309

Step 3:
The number 309 fits into 850 2 times, leaving a remainder of 232.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 618 from 850 leaves us with 232.
Grab the next digit (5) from the dividend, add it to 232, then carry on: 2325 / 309

Advancing to step 4:
When dividing 2325 by 309, we get 7 with a remainder of 162.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 2163 from 2325, we get 162.
Append the next digit (1) from the dividend to 162 and continue with: 1621 / 309

Let's proceed to step 5:
If we divide 1621 by 309, we get 5 and a remainder of 76.
The next digit of our result is 5. 
Result so far: 275.0
If we subtract 1545 from 1621, we get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 309

Going ahead to step 6:
309 can be fit into 766 2 times, resulting in a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 2752.0
Subtracting 618 from 766 leaves us with 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 309

On to step 7:
When dividing 1480 by 309, we get 4 with a remainder of 244.
The number 4 becomes the next digit in our result. 
Result so far: 27524.0
Subtract 1236 from 1480 to get 244.
Include the next digit (7) from the dividend after 244, then repeat: 2447 / 309

Moving on to step 8:
2447 divided by 309 is 7 with a remainder of 284.
Use 7 as the next digit of our solution. 
Result so far: 275247.0
If we take 2163 away from 2447, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 9:
2840 divided by 309 is 9 with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 275247.9
If we take 2781 away from 2840, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
309 goes into 590 1 times with a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 275247.91
If we subtract 309 from 590, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 11:
The number 309 fits into 2810 9 times, leaving a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 275247.919
If we subtract 2781 from 2810, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
If we divide 290 by 309, we get 0 and a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 275247.919
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 13:
309 can be fit into 2900 9 times, resulting in a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 275247.91909
Subtracting 2781 from 2900 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 14:
309 can be fit into 1190 3 times, resulting in a remainder of 263.
Put 3 as the next digit of the answer. 
Result so far: 275247.919093
The remainder is 263 after subtracting 927 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 15:
309 can be fit into 2630 8 times, resulting in a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 275247.9190938
Subtract 2472 from 2630 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 16:
If we divide 1580 by 309, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 275247.91909385
If we take 1545 away from 1580, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 275247.91909385, and the remainder is 3.5e-08.
