We divide 21155138 by 494
The aim is to understand the frequency of 494 in 21155138.

Step 1:
When dividing 2 by 494, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 494

Let's proceed to step 2:
When dividing 21 by 494, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 494

Advancing to step 3:
When dividing 211 by 494, we get 0 with a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 211 after subtracting 0 from 211.
Include the next digit (5) from the dividend after 211, then repeat: 2115 / 494

Moving on to step 4:
When dividing 2115 by 494, we get 4 with a remainder of 139.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1976 from 2115 to get 139.
Include the next digit (5) from the dividend after 139, then repeat: 1395 / 494

Advancing to step 5:
When dividing 1395 by 494, we get 2 with a remainder of 407.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 988 from 1395 to get 407.
Fetch the next digit (1) from the dividend, attach it to 407 and continue: 4071 / 494

On to step 6:
4071 divided by 494 is 8 with a remainder of 119.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
Subtracting 3952 from 4071 leaves us with 119.
Bring next digit (3) of the dividend behind the 119 and repeat the process: 1193 / 494

Step 7:
1193 divided by 494 is 2 with a remainder of 205.
The number 2 becomes the next digit in our result. 
Result so far: 4282.0
Subtracting 988 from 1193 leaves us with 205.
Grab the next digit (8) from the dividend, add it to 205, then carry on: 2058 / 494

On to step 8:
If we divide 2058 by 494, we get 4 and a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 42824.0
The remainder is 82 after subtracting 1976 from 2058.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
If we divide 820 by 494, we get 1 and a remainder of 326.
Put 1 as the next digit of the answer. 
Result so far: 42824.1
The remainder is 326 after subtracting 494 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 10:
If we divide 3260 by 494, we get 6 and a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 42824.16
The remainder is 296 after subtracting 2964 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 11:
494 can be fit into 2960 5 times, resulting in a remainder of 490.
Put 5 as the next digit of the answer. 
Result so far: 42824.165
If we take 2470 away from 2960, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 12:
When dividing 4900 by 494, we get 9 with a remainder of 454.
The number 9 becomes the next digit in our result. 
Result so far: 42824.1659
Subtract 4446 from 4900 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 13:
If we divide 4540 by 494, we get 9 and a remainder of 94.
The next digit of our result is 9. 
Result so far: 42824.16599
If we subtract 4446 from 4540, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The final result is 42824.16599 with a remainder of 9.4e-05.
