1782397 ÷ 439 
The aim is to understand the frequency of 439 in 1782397.

Let's proceed to step 1:
When dividing 1 by 439, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 439

Advancing to step 2:
The number 439 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 439

Moving on to step 3:
If we divide 178 by 439, we get 0 and a remainder of 178.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 178 leaves us with 178.
Fetch the next digit (2) from the dividend, attach it to 178 and continue: 1782 / 439

On to step 4:
The number 439 fits into 1782 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1756 from 1782 to get 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 439

Going ahead to step 5:
The number 439 fits into 263 0 times, leaving a remainder of 263.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 263, we get 263.
Take the next digit (9) from the dividend and append it to 263, then repeat: 2639 / 439

On to step 6:
The number 439 fits into 2639 6 times, leaving a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 406.0
If we take 2634 away from 2639, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 439

On to step 7:
When dividing 57 by 439, we get 0 with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 4060.0
If we take 0 away from 57, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
When dividing 570 by 439, we get 1 with a remainder of 131.
Record the quotient 1 as the next digit in the result. 
Result so far: 4060.1
Deduct 439 from 570 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
When dividing 1310 by 439, we get 2 with a remainder of 432.
Write down 2 as next digit of the result. 
Result so far: 4060.12
If we take 878 away from 1310, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 10:
The number 439 fits into 4320 9 times, leaving a remainder of 369.
Write down 9 as next digit of the result. 
Result so far: 4060.129
Subtracting 3951 from 4320 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 11:
439 can be fit into 3690 8 times, resulting in a remainder of 178.
The next digit of our result is 8. 
Result so far: 4060.1298
Subtracting 3512 from 3690 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 12:
The number 439 fits into 1780 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 4060.12984
Deduct 1756 from 1780 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
240 divided by 439 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 4060.12984
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
439 goes into 2400 5 times with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 4060.1298405
If we subtract 2195 from 2400, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 15:
The number 439 fits into 2050 4 times, leaving a remainder of 294.
The next digit of our result is 4. 
Result so far: 4060.12984054
Subtracting 1756 from 2050 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Our division results in 4060.12984054 with a remaining 2.94e-07.
