72060173 ÷ 439 
The aim is to understand the frequency of 439 in 72060173.

On to step 1:
439 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 439

Going ahead to step 2:
The number 439 fits into 72 0 times, leaving a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 439

Advancing to step 3:
If we divide 720 by 439, we get 1 and a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 439 from 720 leaves us with 281.
Fetch the next digit (6) from the dividend, attach it to 281 and continue: 2816 / 439

Moving on to step 4:
The number 439 fits into 2816 6 times, leaving a remainder of 182.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 2634 from 2816, we get 182.
Fetch the next digit (0) from the dividend, attach it to 182 and continue: 1820 / 439

Step 5:
When dividing 1820 by 439, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 164.0
Subtract 1756 from 1820 to get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 439

Step 6:
641 divided by 439 is 1 with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 1641.0
Deduct 439 from 641 and we're left with 202.
Fetch the next digit (7) from the dividend, attach it to 202 and continue: 2027 / 439

Moving on to step 7:
439 goes into 2027 4 times with a remainder of 271.
Write down 4 as next digit of the result. 
Result so far: 16414.0
The remainder is 271 after subtracting 1756 from 2027.
Grab the next digit (3) from the dividend, add it to 271, then carry on: 2713 / 439

Moving on to step 8:
If we divide 2713 by 439, we get 6 and a remainder of 79.
The number 6 becomes the next digit in our result. 
Result so far: 164146.0
The remainder is 79 after subtracting 2634 from 2713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
When dividing 790 by 439, we get 1 with a remainder of 351.
The number 1 becomes the next digit in our result. 
Result so far: 164146.1
If we take 439 away from 790, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 10:
If we divide 3510 by 439, we get 7 and a remainder of 437.
The next digit of our result is 7. 
Result so far: 164146.17
Subtracting 3073 from 3510 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 11:
4370 divided by 439 is 9 with a remainder of 419.
The next digit of our result is 9. 
Result so far: 164146.179
The remainder is 419 after subtracting 3951 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 12:
439 goes into 4190 9 times with a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 164146.1799
Subtract 3951 from 4190 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

The quotient of the division is 164146.1799, and the remainder is 0.00239.
