We're dividing 27631564 by 688 
The aim is to understand the frequency of 688 in 27631564.

Let's proceed to step 1:
When dividing 2 by 688, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 688

Let's proceed to step 2:
If we divide 27 by 688, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 688

Step 3:
276 divided by 688 is 0 with a remainder of 276.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 276 to get 276.
Fetch the next digit (3) from the dividend, attach it to 276 and continue: 2763 / 688

Step 4:
2763 divided by 688 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2752 from 2763 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 688

On to step 5:
688 can be fit into 111 0 times, resulting in a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 111 after subtracting 0 from 111.
Include the next digit (5) from the dividend after 111, then repeat: 1115 / 688

Moving on to step 6:
When dividing 1115 by 688, we get 1 with a remainder of 427.
Write down 1 as next digit of the result. 
Result so far: 401.0
If we subtract 688 from 1115, we get 427.
Take the next digit (6) from the dividend and append it to 427, then repeat: 4276 / 688

Advancing to step 7:
The number 688 fits into 4276 6 times, leaving a remainder of 148.
Put 6 as the next digit of the answer. 
Result so far: 4016.0
Subtract 4128 from 4276 to get 148.
Fetch the next digit (4) from the dividend, attach it to 148 and continue: 1484 / 688

On to step 8:
688 can be fit into 1484 2 times, resulting in a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 40162.0
If we subtract 1376 from 1484, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
The number 688 fits into 1080 1 times, leaving a remainder of 392.
The next digit of our result is 1. 
Result so far: 40162.1
If we subtract 688 from 1080, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
If we divide 3920 by 688, we get 5 and a remainder of 480.
Use 5 as the next digit of our solution. 
Result so far: 40162.15
Subtracting 3440 from 3920 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
If we divide 4800 by 688, we get 6 and a remainder of 672.
Put 6 as the next digit of the answer. 
Result so far: 40162.156
If we subtract 4128 from 4800, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 12:
The number 688 fits into 6720 9 times, leaving a remainder of 528.
Record the quotient 9 as the next digit in the result. 
Result so far: 40162.1569
Subtract 6192 from 6720 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 13:
The number 688 fits into 5280 7 times, leaving a remainder of 464.
Use 7 as the next digit of our solution. 
Result so far: 40162.15697
Subtract 4816 from 5280 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 14:
688 goes into 4640 6 times with a remainder of 512.
The next digit of our result is 6. 
Result so far: 40162.156976
The remainder is 512 after subtracting 4128 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 15:
5120 divided by 688 is 7 with a remainder of 304.
The number 7 becomes the next digit in our result. 
Result so far: 40162.1569767
Deduct 4816 from 5120 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 16:
If we divide 3040 by 688, we get 4 and a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 40162.15697674
Subtract 2752 from 3040 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

After the division, we end up with 40162.15697674 and a remainder of 2.88e-07.
