Let's divide 27541519 by 686
The aim is to understand the frequency of 686 in 27541519.

Let's proceed to step 1:
The number 686 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 686

Moving on to step 2:
686 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 686

Moving on to step 3:
The number 686 fits into 275 0 times, leaving a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 275 after subtracting 0 from 275.
Grab the next digit (4) from the dividend, add it to 275, then carry on: 2754 / 686

Going ahead to step 4:
2754 divided by 686 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2744 from 2754 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 686

On to step 5:
When dividing 101 by 686, we get 0 with a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 101 leaves us with 101.
Grab the next digit (5) from the dividend, add it to 101, then carry on: 1015 / 686

Moving on to step 6:
686 can be fit into 1015 1 times, resulting in a remainder of 329.
Put 1 as the next digit of the answer. 
Result so far: 401.0
If we take 686 away from 1015, we end up with 329.
Fetch the next digit (1) from the dividend, attach it to 329 and continue: 3291 / 686

Let's proceed to step 7:
The number 686 fits into 3291 4 times, leaving a remainder of 547.
The next digit of our result is 4. 
Result so far: 4014.0
Subtracting 2744 from 3291 leaves us with 547.
Include the next digit (9) from the dividend after 547, then repeat: 5479 / 686

Step 8:
686 goes into 5479 7 times with a remainder of 677.
Put 7 as the next digit of the answer. 
Result so far: 40147.0
The remainder is 677 after subtracting 4802 from 5479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Moving on to step 9:
6770 divided by 686 is 9 with a remainder of 596.
The next digit of our result is 9. 
Result so far: 40147.9
Deduct 6174 from 6770 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 10:
The number 686 fits into 5960 8 times, leaving a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 40147.98
If we take 5488 away from 5960, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 11:
When dividing 4720 by 686, we get 6 with a remainder of 604.
Record the quotient 6 as the next digit in the result. 
Result so far: 40147.986
Deduct 4116 from 4720 and we're left with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 12:
When dividing 6040 by 686, we get 8 with a remainder of 552.
Record the quotient 8 as the next digit in the result. 
Result so far: 40147.9868
If we take 5488 away from 6040, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 13:
If we divide 5520 by 686, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 40147.98688
The remainder is 32 after subtracting 5488 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 40147.98688 with a remainder of 3.2e-05.
