We look at the division of 251687 by 69 
The aim is to understand the frequency of 69 in 251687.

On to step 1:
69 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 69

Step 2:
If we divide 25 by 69, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 69

Advancing to step 3:
69 goes into 251 3 times with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 207 from 251 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 69

Advancing to step 4:
If we divide 446 by 69, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 32 after subtracting 414 from 446.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 69

Advancing to step 5:
69 can be fit into 328 4 times, resulting in a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 364.0
The remainder is 52 after subtracting 276 from 328.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 69

Going ahead to step 6:
69 can be fit into 527 7 times, resulting in a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 3647.0
The remainder is 44 after subtracting 483 from 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
If we divide 440 by 69, we get 6 and a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 3647.6
Deduct 414 from 440 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
If we divide 260 by 69, we get 3 and a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 3647.63
The remainder is 53 after subtracting 207 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
The number 69 fits into 530 7 times, leaving a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 3647.637
The remainder is 47 after subtracting 483 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
If we divide 470 by 69, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 3647.6376
If we take 414 away from 470, we end up 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.

Advancing to step 11:
If we divide 560 by 69, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3647.63768
If we subtract 552 from 560, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 69, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 3647.637681
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
When dividing 110 by 69, we get 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 3647.6376811
The remainder is 41 after subtracting 69 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 3647.6376811 with a remaining 4.1e-07.
