72518330 ÷ 127 
The aim is to understand the frequency of 127 in 72518330.

On to step 1:
The number 127 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 127

On to step 2:
127 goes into 72 0 times with 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.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 127

Step 3:
If we divide 725 by 127, we get 5 and a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 635 from 725 leaves us with 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 127

Advancing to step 4:
When dividing 901 by 127, we get 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtract 889 from 901 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 127

Moving on to step 5:
The number 127 fits into 128 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 571.0
Subtract 127 from 128 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 127

Going ahead to step 6:
When dividing 13 by 127, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 5710.0
Subtract 0 from 13 to get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 127

Advancing to step 7:
If we divide 133 by 127, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 57101.0
If we take 127 away from 133, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 127

On to step 8:
60 divided by 127 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 571010.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
The number 127 fits into 600 4 times, leaving a remainder of 92.
The next digit of our result is 4. 
Result so far: 571010.4
If we subtract 508 from 600, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
If we divide 920 by 127, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 571010.47
Deduct 889 from 920 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
The number 127 fits into 310 2 times, leaving a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 571010.472
Deduct 254 from 310 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
127 goes into 560 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 571010.4724
Deduct 508 from 560 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 13:
When dividing 520 by 127, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 571010.47244
Subtract 508 from 520 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 571010.47244, with a leftover of 1.2e-05.
