72780228 ÷ 439 
The aim is to understand the frequency of 439 in 72780228.

On to step 1:
If we divide 7 by 439, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 439

Let's proceed to step 2:
When dividing 72 by 439, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 439

Moving on to step 3:
When dividing 727 by 439, we get 1 with a remainder of 288.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 439 from 727 and we're left with 288.
Grab the next digit (8) from the dividend, add it to 288, then carry on: 2888 / 439

Let's proceed to step 4:
439 goes into 2888 6 times with a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 254 after subtracting 2634 from 2888.
Grab the next digit (0) from the dividend, add it to 254, then carry on: 2540 / 439

Step 5:
2540 divided by 439 is 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we subtract 2195 from 2540, we get 345.
Append the next digit (2) from the dividend to 345 and continue with: 3452 / 439

Advancing to step 6:
The number 439 fits into 3452 7 times, leaving a remainder of 379.
The number 7 becomes the next digit in our result. 
Result so far: 1657.0
Deduct 3073 from 3452 and we're left with 379.
Grab the next digit (2) from the dividend, add it to 379, then carry on: 3792 / 439

Advancing to step 7:
The number 439 fits into 3792 8 times, leaving a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 16578.0
If we take 3512 away from 3792, we end up with 280.
Include the next digit (8) from the dividend after 280, then repeat: 2808 / 439

Going ahead to step 8:
When dividing 2808 by 439, we get 6 with a remainder of 174.
Write down 6 as next digit of the result. 
Result so far: 165786.0
Subtracting 2634 from 2808 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
439 goes into 1740 3 times with a remainder of 423.
Write down 3 as next digit of the result. 
Result so far: 165786.3
If we subtract 1317 from 1740, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 10:
439 goes into 4230 9 times with a remainder of 279.
Use 9 as the next digit of our solution. 
Result so far: 165786.39
Subtracting 3951 from 4230 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 11:
439 goes into 2790 6 times with a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 165786.396
Deduct 2634 from 2790 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 12:
If we divide 1560 by 439, we get 3 and a remainder of 243.
Write down 3 as next digit of the result. 
Result so far: 165786.3963
Deduct 1317 from 1560 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Step 13:
When dividing 2430 by 439, we get 5 with a remainder of 235.
The next digit of our result is 5. 
Result so far: 165786.39635
Subtract 2195 from 2430 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 14:
When dividing 2350 by 439, we get 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 165786.396355
If we subtract 2195 from 2350, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 165786.396355 with a remaining 1.55e-05.
