We look at the division of 161387 by 69 
The aim is to understand the frequency of 69 in 161387.

Going ahead to step 1:
69 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 69

Step 2:
If we divide 16 by 69, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 69

On to step 3:
If we divide 161 by 69, we get 2 and a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 23 after subtracting 138 from 161.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 69

Step 4:
69 goes into 233 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 207 from 233, we get 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 69

On to step 5:
The number 69 fits into 268 3 times, leaving a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
If we take 207 away from 268, we end up with 61.
Bring next digit (7) of the dividend behind the 61 and repeat the process: 617 / 69

Going ahead to step 6:
617 divided by 69 is 8 with a remainder of 65.
The next digit of our result is 8. 
Result so far: 2338.0
If we subtract 552 from 617, we get 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:
650 divided by 69 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 2338.9
The remainder is 29 after subtracting 621 from 650.
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:
69 can be fit into 290 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 2338.94
If we take 276 away from 290, we end up 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.

Let's proceed to step 9:
69 can be fit into 140 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2338.942
Deduct 138 from 140 and we're left 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.

Let's proceed to step 10:
69 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 2338.942
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
The number 69 fits into 200 2 times, leaving a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 2338.94202
Deduct 138 from 200 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 12:
When dividing 620 by 69, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 2338.942028
The remainder is 68 after subtracting 552 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to 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: 2338.9420289
Subtract 621 from 680 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
The number 69 fits into 590 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 2338.94202898
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 quotient of the division is 2338.94202898, and the remainder is 3.8e-08.
