Let's divide 21817024 by 939
The aim is to understand the frequency of 939 in 21817024.

Step 1:
939 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 939

On to step 2:
If we divide 21 by 939, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 939

Going ahead to step 3:
218 divided by 939 is 0 with a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Include the next digit (1) from the dividend after 218, then repeat: 2181 / 939

Advancing to step 4:
The number 939 fits into 2181 2 times, leaving a remainder of 303.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1878 from 2181 leaves us with 303.
Grab the next digit (7) from the dividend, add it to 303, then carry on: 3037 / 939

Going ahead to step 5:
939 can be fit into 3037 3 times, resulting in a remainder of 220.
Write down 3 as next digit of the result. 
Result so far: 23.0
Deduct 2817 from 3037 and we're left with 220.
Include the next digit (0) from the dividend after 220, then repeat: 2200 / 939

Going ahead to step 6:
939 can be fit into 2200 2 times, resulting in a remainder of 322.
The next digit of our result is 2. 
Result so far: 232.0
Subtracting 1878 from 2200 leaves us with 322.
Take the next digit (2) from the dividend and append it to 322, then repeat: 3222 / 939

Step 7:
939 can be fit into 3222 3 times, resulting in a remainder of 405.
Use 3 as the next digit of our solution. 
Result so far: 2323.0
Deduct 2817 from 3222 and we're left with 405.
Bring next digit (4) of the dividend behind the 405 and repeat the process: 4054 / 939

Let's proceed to step 8:
939 can be fit into 4054 4 times, resulting in a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 23234.0
The remainder is 298 after subtracting 3756 from 4054.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 9:
939 can be fit into 2980 3 times, resulting in a remainder of 163.
The next digit of our result is 3. 
Result so far: 23234.3
Subtracting 2817 from 2980 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 10:
When dividing 1630 by 939, we get 1 with a remainder of 691.
Use 1 as the next digit of our solution. 
Result so far: 23234.31
Deduct 939 from 1630 and we're left with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Going ahead to step 11:
939 can be fit into 6910 7 times, resulting in a remainder of 337.
Put 7 as the next digit of the answer. 
Result so far: 23234.317
Subtract 6573 from 6910 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 12:
If we divide 3370 by 939, we get 3 and a remainder of 553.
The number 3 becomes the next digit in our result. 
Result so far: 23234.3173
If we subtract 2817 from 3370, we get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Step 13:
5530 divided by 939 is 5 with a remainder of 835.
Record the quotient 5 as the next digit in the result. 
Result so far: 23234.31735
Subtracting 4695 from 5530 leaves us with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Going ahead to step 14:
If we divide 8350 by 939, we get 8 and a remainder of 838.
The number 8 becomes the next digit in our result. 
Result so far: 23234.317358
The remainder is 838 after subtracting 7512 from 8350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Moving on to step 15:
If we divide 8380 by 939, we get 8 and a remainder of 868.
The next digit of our result is 8. 
Result so far: 23234.3173588
If we take 7512 away from 8380, we end up with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

The final result is 23234.3173588 with a remainder of 8.68e-06.
