21093945 ÷ 127 
The aim is to understand the frequency of 127 in 21093945.

Step 1:
The number 127 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
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 127

Moving on to step 2:
21 divided by 127 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 127

Going ahead to step 3:
127 goes into 210 1 times with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 127 from 210 leaves us with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 127

Moving on to step 4:
839 divided by 127 is 6 with a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 762 from 839 and we're left with 77.
Append the next digit (3) from the dividend to 77 and continue with: 773 / 127

Advancing to step 5:
127 goes into 773 6 times with a remainder of 11.
The next digit of our result is 6. 
Result so far: 166.0
The remainder is 11 after subtracting 762 from 773.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 127

On to step 6:
127 goes into 119 0 times with a remainder of 119.
The number 0 becomes the next digit in our result. 
Result so far: 1660.0
If we subtract 0 from 119, we get 119.
Include the next digit (4) from the dividend after 119, then repeat: 1194 / 127

On to step 7:
127 goes into 1194 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 16609.0
If we take 1143 away from 1194, we end up with 51.
Append the next digit (5) from the dividend to 51 and continue with: 515 / 127

Going ahead to step 8:
If we divide 515 by 127, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 166094.0
If we take 508 away from 515, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
If we divide 70 by 127, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 166094.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
If we divide 700 by 127, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 166094.05
Deduct 635 from 700 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
If we divide 650 by 127, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 166094.055
The remainder is 15 after subtracting 635 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 166094.055 with a balance of 0.0015.
