We're dividing 7657520 by 439 
The aim is to understand the frequency of 439 in 7657520.

Advancing to step 1:
If we divide 7 by 439, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 439

On to step 2:
439 goes into 76 0 times with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 439

On to step 3:
439 goes into 765 1 times with a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 439 from 765 to get 326.
Append the next digit (7) from the dividend to 326 and continue with: 3267 / 439

Let's proceed to step 4:
3267 divided by 439 is 7 with a remainder of 194.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 3073 from 3267, we get 194.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 439

Let's proceed to step 5:
439 can be fit into 1945 4 times, resulting in a remainder of 189.
The next digit of our result is 4. 
Result so far: 174.0
Deduct 1756 from 1945 and we're left with 189.
Fetch the next digit (2) from the dividend, attach it to 189 and continue: 1892 / 439

Moving on to step 6:
439 goes into 1892 4 times with a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 1744.0
Subtract 1756 from 1892 to get 136.
Take the next digit (0) from the dividend and append it to 136, then repeat: 1360 / 439

Moving on to step 7:
439 can be fit into 1360 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 17443.0
Subtract 1317 from 1360 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
439 goes into 430 0 times with a remainder of 430.
The number 0 becomes the next digit in our result. 
Result so far: 17443.0
Deduct 0 from 430 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 9:
4300 divided by 439 is 9 with a remainder of 349.
Record the quotient 9 as the next digit in the result. 
Result so far: 17443.09
Deduct 3951 from 4300 and we're left with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Moving on to step 10:
439 can be fit into 3490 7 times, resulting in a remainder of 417.
Put 7 as the next digit of the answer. 
Result so far: 17443.097
Deduct 3073 from 3490 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Moving on to step 11:
439 can be fit into 4170 9 times, resulting in a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 17443.0979
If we subtract 3951 from 4170, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 12:
When dividing 2190 by 439, we get 4 with a remainder of 434.
Use 4 as the next digit of our solution. 
Result so far: 17443.09794
The remainder is 434 after subtracting 1756 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 13:
If we divide 4340 by 439, we get 9 and a remainder of 389.
Record the quotient 9 as the next digit in the result. 
Result so far: 17443.097949
Deduct 3951 from 4340 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Advancing to step 14:
3890 divided by 439 is 8 with a remainder of 378.
Record the quotient 8 as the next digit in the result. 
Result so far: 17443.0979498
Subtracting 3512 from 3890 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 15:
If we divide 3780 by 439, we get 8 and a remainder of 268.
Put 8 as the next digit of the answer. 
Result so far: 17443.09794988
If we subtract 3512 from 3780, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Our division results in 17443.09794988 with a remaining 2.68e-07.
