Let's divide 21099360 by 938
The aim is to understand the frequency of 938 in 21099360.

Step 1:
When dividing 2 by 938, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 938

Let's proceed to step 2:
938 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 938

On to step 3:
If we divide 210 by 938, we get 0 and a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Include the next digit (9) from the dividend after 210, then repeat: 2109 / 938

Moving on to step 4:
938 goes into 2109 2 times with a remainder of 233.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1876 from 2109, we get 233.
Grab the next digit (9) from the dividend, add it to 233, then carry on: 2339 / 938

Step 5:
938 goes into 2339 2 times with a remainder of 463.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 1876 away from 2339, we end up with 463.
Fetch the next digit (3) from the dividend, attach it to 463 and continue: 4633 / 938

Advancing to step 6:
If we divide 4633 by 938, we get 4 and a remainder of 881.
Write down 4 as next digit of the result. 
Result so far: 224.0
Deduct 3752 from 4633 and we're left with 881.
Take the next digit (6) from the dividend and append it to 881, then repeat: 8816 / 938

Moving on to step 7:
If we divide 8816 by 938, we get 9 and a remainder of 374.
Write down 9 as next digit of the result. 
Result so far: 2249.0
If we take 8442 away from 8816, we end up with 374.
Include the next digit (0) from the dividend after 374, then repeat: 3740 / 938

Step 8:
The number 938 fits into 3740 3 times, leaving a remainder of 926.
Put 3 as the next digit of the answer. 
Result so far: 22493.0
Deduct 2814 from 3740 and we're left with 926.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9260, and continue the process.

Let's proceed to step 9:
If we divide 9260 by 938, we get 9 and a remainder of 818.
Record the quotient 9 as the next digit in the result. 
Result so far: 22493.9
Subtracting 8442 from 9260 leaves us with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Let's proceed to step 10:
938 goes into 8180 8 times with a remainder of 676.
The next digit of our result is 8. 
Result so far: 22493.98
Subtracting 7504 from 8180 leaves us with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Going ahead to step 11:
When dividing 6760 by 938, we get 7 with a remainder of 194.
Write down 7 as next digit of the result. 
Result so far: 22493.987
The remainder is 194 after subtracting 6566 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 12:
When dividing 1940 by 938, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 22493.9872
Deduct 1876 from 1940 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
938 can be fit into 640 0 times, resulting in a remainder of 640.
The next digit of our result is 0. 
Result so far: 22493.9872
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
When dividing 6400 by 938, we get 6 with a remainder of 772.
The number 6 becomes the next digit in our result. 
Result so far: 22493.987206
Deduct 5628 from 6400 and we're left with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Advancing to step 15:
If we divide 7720 by 938, we get 8 and a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 22493.9872068
If we subtract 7504 from 7720, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 16:
When dividing 2160 by 938, we get 2 with a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 22493.98720682
If we take 1876 away from 2160, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 22493.98720682 with a balance of 2.84e-07.
