We look at the division of 21729576 by 985 
The aim is to understand the frequency of 985 in 21729576.

Let's proceed to step 1:
If we divide 2 by 985, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 985

Advancing to step 2:
985 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 985

Step 3:
The number 985 fits into 217 0 times, leaving a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Take the next digit (2) from the dividend and append it to 217, then repeat: 2172 / 985

On to step 4:
2172 divided by 985 is 2 with a remainder of 202.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1970 from 2172 and we're left with 202.
Grab the next digit (9) from the dividend, add it to 202, then carry on: 2029 / 985

Going ahead to step 5:
2029 divided by 985 is 2 with a remainder of 59.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 1970 from 2029, we get 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 985

Let's proceed to step 6:
The number 985 fits into 595 0 times, leaving a remainder of 595.
The number 0 becomes the next digit in our result. 
Result so far: 220.0
If we take 0 away from 595, we end up with 595.
Append the next digit (7) from the dividend to 595 and continue with: 5957 / 985

Going ahead to step 7:
The number 985 fits into 5957 6 times, leaving a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 2206.0
The remainder is 47 after subtracting 5910 from 5957.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 985

Advancing to step 8:
When dividing 476 by 985, we get 0 with a remainder of 476.
The number 0 becomes the next digit in our result. 
Result so far: 22060.0
If we take 0 away from 476, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 9:
985 can be fit into 4760 4 times, resulting in a remainder of 820.
Put 4 as the next digit of the answer. 
Result so far: 22060.4
If we take 3940 away from 4760, we end up with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Step 10:
When dividing 8200 by 985, we get 8 with a remainder of 320.
Put 8 as the next digit of the answer. 
Result so far: 22060.48
Subtracting 7880 from 8200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 11:
When dividing 3200 by 985, we get 3 with a remainder of 245.
Use 3 as the next digit of our solution. 
Result so far: 22060.483
If we subtract 2955 from 3200, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 12:
985 goes into 2450 2 times with a remainder of 480.
The next digit of our result is 2. 
Result so far: 22060.4832
Deduct 1970 from 2450 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
The number 985 fits into 4800 4 times, leaving a remainder of 860.
Write down 4 as next digit of the result. 
Result so far: 22060.48324
Deduct 3940 from 4800 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Going ahead to step 14:
985 goes into 8600 8 times with a remainder of 720.
The number 8 becomes the next digit in our result. 
Result so far: 22060.483248
Deduct 7880 from 8600 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 15:
When dividing 7200 by 985, we get 7 with a remainder of 305.
Put 7 as the next digit of the answer. 
Result so far: 22060.4832487
If we take 6895 away from 7200, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 16:
3050 divided by 985 is 3 with a remainder of 95.
The next digit of our result is 3. 
Result so far: 22060.48324873
Subtracting 2955 from 3050 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The final outcome is 22060.48324873, with a leftover of 9.5e-08.
