We look at the division of 120031 by 69 
The aim is to understand the frequency of 69 in 120031.

Step 1:
When dividing 1 by 69, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 69

Let's proceed to step 2:
The number 69 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 69

On to step 3:
The number 69 fits into 120 1 times, leaving a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 69 from 120 leaves us with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 69

Going ahead to step 4:
510 divided by 69 is 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 483 away from 510, we end up with 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 69

Let's proceed to step 5:
69 goes into 273 3 times with a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 173.0
Deduct 207 from 273 and we're left with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 69

Moving on to step 6:
661 divided by 69 is 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 1739.0
Subtract 621 from 661 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
When dividing 400 by 69, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 1739.5
The remainder is 55 after subtracting 345 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
If we divide 550 by 69, we get 7 and a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 1739.57
The remainder is 67 after subtracting 483 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
The number 69 fits into 670 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 1739.579
Deduct 621 from 670 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 10:
69 goes into 490 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1739.5797
Deduct 483 from 490 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
69 can be fit into 70 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1739.57971
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
If we divide 10 by 69, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1739.57971
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 69 fits into 100 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1739.5797101
The remainder is 31 after subtracting 69 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
If we divide 310 by 69, we get 4 and a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 1739.57971014
If we take 276 away from 310, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 1739.57971014 and a remainder of 3.4e-08.
