257610 ÷ 69 
The aim is to understand the frequency of 69 in 257610.

Advancing to step 1:
69 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 69

Advancing to step 2:
When dividing 25 by 69, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 69

Advancing to step 3:
The number 69 fits into 257 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 207 from 257 and we're left with 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 69

On to step 4:
506 divided by 69 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 483 from 506 to get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 69

Advancing to step 5:
If we divide 231 by 69, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
Deduct 207 from 231 and we're left with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 69

Going ahead to step 6:
If we divide 240 by 69, we get 3 and a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 3733.0
The remainder is 33 after subtracting 207 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
The number 69 fits into 330 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 3733.4
Subtracting 276 from 330 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
If we divide 540 by 69, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 3733.47
Deduct 483 from 540 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
69 goes into 570 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 3733.478
The remainder is 18 after subtracting 552 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
When dividing 180 by 69, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 3733.4782
Subtracting 138 from 180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
If we divide 420 by 69, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 3733.47826
The remainder is 6 after subtracting 414 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
69 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3733.47826
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
600 divided by 69 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 3733.4782608
Subtracting 552 from 600 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
69 goes into 480 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 3733.47826086
If we take 414 away from 480, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 3733.47826086, with a leftover of 6.6e-08.
