We look at the division of 139307 by 69 
The aim is to understand the frequency of 69 in 139307.

Step 1:
69 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 69

Advancing to step 2:
If we divide 13 by 69, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 69

Going ahead to step 3:
139 divided by 69 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 138 from 139 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 69

Step 4:
When dividing 13 by 69, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 13, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 69

Let's proceed to step 5:
The number 69 fits into 130 1 times, leaving a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 201.0
Deduct 69 from 130 and we're left with 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 69

On to step 6:
617 divided by 69 is 8 with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 2018.0
Subtracting 552 from 617 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
The number 69 fits into 650 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 2018.9
Deduct 621 from 650 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
When dividing 290 by 69, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 2018.94
Subtracting 276 from 290 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 69, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2018.942
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
69 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2018.942
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
69 can be fit into 200 2 times, resulting in a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 2018.94202
Subtract 138 from 200 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
69 can be fit into 620 8 times, resulting in a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 2018.942028
If we take 552 away from 620, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
If we divide 680 by 69, we get 9 and a remainder of 59.
The next digit of our result is 9. 
Result so far: 2018.9420289
Deduct 621 from 680 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 14:
590 divided by 69 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 2018.94202898
Deduct 552 from 590 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 2018.94202898 with a remainder of 3.8e-08.
