We look at the division of 80442225 by 307 
The aim is to understand the frequency of 307 in 80442225.

Step 1:
The number 307 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 307

Advancing to step 2:
80 divided by 307 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 307

Advancing to step 3:
If we divide 804 by 307, we get 2 and a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 190 after subtracting 614 from 804.
Bring next digit (4) of the dividend behind the 190 and repeat the process: 1904 / 307

Moving on to step 4:
307 goes into 1904 6 times with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 62 after subtracting 1842 from 1904.
Grab the next digit (2) from the dividend, add it to 62, then carry on: 622 / 307

Advancing to step 5:
307 can be fit into 622 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 262.0
If we subtract 614 from 622, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 307

Moving on to step 6:
307 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 2620.0
Deduct 0 from 82 and we're left with 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 307

On to step 7:
307 can be fit into 822 2 times, resulting in a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 26202.0
Subtract 614 from 822 to get 208.
Grab the next digit (5) from the dividend, add it to 208, then carry on: 2085 / 307

Let's proceed to step 8:
When dividing 2085 by 307, we get 6 with a remainder of 243.
Put 6 as the next digit of the answer. 
Result so far: 262026.0
If we subtract 1842 from 2085, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 9:
2430 divided by 307 is 7 with a remainder of 281.
Use 7 as the next digit of our solution. 
Result so far: 262026.7
Deduct 2149 from 2430 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Moving on to step 10:
307 goes into 2810 9 times with a remainder of 47.
The next digit of our result is 9. 
Result so far: 262026.79
If we subtract 2763 from 2810, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
307 goes into 470 1 times with a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 262026.791
Subtracting 307 from 470 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.

Moving on to step 12:
When dividing 1630 by 307, we get 5 with a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 262026.7915
If we subtract 1535 from 1630, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 13:
307 goes into 950 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 262026.79153
Deduct 921 from 950 and we're left with 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 14:
When dividing 290 by 307, we get 0 with a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 262026.79153
If we take 0 away from 290, we end up 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.

Advancing to step 15:
2900 divided by 307 is 9 with a remainder of 137.
Record the quotient 9 as the next digit in the result. 
Result so far: 262026.7915309
Subtract 2763 from 2900 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 16:
307 can be fit into 1370 4 times, resulting in a remainder of 142.
The number 4 becomes the next digit in our result. 
Result so far: 262026.79153094
The remainder is 142 after subtracting 1228 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 262026.79153094 with a remaining 1.42e-07.
