21008555 ÷ 926 
The aim is to understand the frequency of 926 in 21008555.

Moving on to step 1:
2 divided by 926 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 926

Let's proceed to step 2:
21 divided by 926 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 926

Let's proceed to step 3:
If we divide 210 by 926, we get 0 and a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Take the next digit (0) from the dividend and append it to 210, then repeat: 2100 / 926

Going ahead to step 4:
The number 926 fits into 2100 2 times, leaving a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1852 from 2100 leaves us with 248.
Bring next digit (8) of the dividend behind the 248 and repeat the process: 2488 / 926

Going ahead to step 5:
When dividing 2488 by 926, we get 2 with a remainder of 636.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 1852 from 2488 and we're left with 636.
Append the next digit (5) from the dividend to 636 and continue with: 6365 / 926

Step 6:
6365 divided by 926 is 6 with a remainder of 809.
The next digit of our result is 6. 
Result so far: 226.0
The remainder is 809 after subtracting 5556 from 6365.
Bring next digit (5) of the dividend behind the 809 and repeat the process: 8095 / 926

Let's proceed to step 7:
8095 divided by 926 is 8 with a remainder of 687.
Put 8 as the next digit of the answer. 
Result so far: 2268.0
If we subtract 7408 from 8095, we get 687.
Grab the next digit (5) from the dividend, add it to 687, then carry on: 6875 / 926

Let's proceed to step 8:
926 goes into 6875 7 times with a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 22687.0
If we take 6482 away from 6875, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 9:
If we divide 3930 by 926, we get 4 and a remainder of 226.
Write down 4 as next digit of the result. 
Result so far: 22687.4
Subtracting 3704 from 3930 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
The number 926 fits into 2260 2 times, leaving a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 22687.42
If we take 1852 away from 2260, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 11:
The number 926 fits into 4080 4 times, leaving a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 22687.424
If we take 3704 away from 4080, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 12:
When dividing 3760 by 926, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 22687.4244
If we subtract 3704 from 3760, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 22687.4244 with a balance of 0.00056.
