We're dividing 21341366 by 688 
The aim is to understand the frequency of 688 in 21341366.

Moving on to step 1:
When dividing 2 by 688, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 688

Advancing to step 2:
The number 688 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 688

Going ahead to step 3:
688 goes into 213 0 times with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Bring next digit (4) of the dividend behind the 213 and repeat the process: 2134 / 688

Going ahead to step 4:
688 can be fit into 2134 3 times, resulting in a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 2064 from 2134, we get 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 688

Going ahead to step 5:
688 goes into 701 1 times with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 688 from 701 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 688

Step 6:
If we divide 133 by 688, we get 0 and a remainder of 133.
Use 0 as the next digit of our solution. 
Result so far: 310.0
Subtract 0 from 133 to get 133.
Include the next digit (6) from the dividend after 133, then repeat: 1336 / 688

Going ahead to step 7:
688 goes into 1336 1 times with a remainder of 648.
Write down 1 as next digit of the result. 
Result so far: 3101.0
Subtracting 688 from 1336 leaves us with 648.
Fetch the next digit (6) from the dividend, attach it to 648 and continue: 6486 / 688

Step 8:
6486 divided by 688 is 9 with a remainder of 294.
Write down 9 as next digit of the result. 
Result so far: 31019.0
If we take 6192 away from 6486, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 9:
688 can be fit into 2940 4 times, resulting in a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 31019.4
If we take 2752 away from 2940, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
If we divide 1880 by 688, we get 2 and a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 31019.42
Subtract 1376 from 1880 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 11:
688 can be fit into 5040 7 times, resulting in a remainder of 224.
Write down 7 as next digit of the result. 
Result so far: 31019.427
If we take 4816 away from 5040, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
2240 divided by 688 is 3 with a remainder of 176.
The number 3 becomes the next digit in our result. 
Result so far: 31019.4273
If we subtract 2064 from 2240, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 13:
When dividing 1760 by 688, we get 2 with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 31019.42732
The remainder is 384 after subtracting 1376 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 14:
The number 688 fits into 3840 5 times, leaving a remainder of 400.
Put 5 as the next digit of the answer. 
Result so far: 31019.427325
The remainder is 400 after subtracting 3440 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 15:
4000 divided by 688 is 5 with a remainder of 560.
The number 5 becomes the next digit in our result. 
Result so far: 31019.4273255
Subtracting 3440 from 4000 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

In conclusion, the division gives 31019.4273255 with a balance of 5.6e-06.
