We look at the division of 13438462 by 490 
The aim is to understand the frequency of 490 in 13438462.

Going ahead to step 1:
1 divided by 490 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 490

Let's proceed to step 2:
490 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 490

Let's proceed to step 3:
134 divided by 490 is 0 with a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 134 and we're left with 134.
Include the next digit (3) from the dividend after 134, then repeat: 1343 / 490

Step 4:
The number 490 fits into 1343 2 times, leaving a remainder of 363.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 980 from 1343 leaves us with 363.
Include the next digit (8) from the dividend after 363, then repeat: 3638 / 490

Advancing to step 5:
The number 490 fits into 3638 7 times, leaving a remainder of 208.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 3430 from 3638 leaves us with 208.
Take the next digit (4) from the dividend and append it to 208, then repeat: 2084 / 490

Step 6:
2084 divided by 490 is 4 with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 274.0
Deduct 1960 from 2084 and we're left with 124.
Bring next digit (6) of the dividend behind the 124 and repeat the process: 1246 / 490

Going ahead to step 7:
When dividing 1246 by 490, we get 2 with a remainder of 266.
Put 2 as the next digit of the answer. 
Result so far: 2742.0
Subtract 980 from 1246 to get 266.
Include the next digit (2) from the dividend after 266, then repeat: 2662 / 490

Let's proceed to step 8:
If we divide 2662 by 490, we get 5 and a remainder of 212.
Put 5 as the next digit of the answer. 
Result so far: 27425.0
If we subtract 2450 from 2662, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 9:
2120 divided by 490 is 4 with a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 27425.4
Subtract 1960 from 2120 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
490 goes into 1600 3 times with a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 27425.43
If we subtract 1470 from 1600, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 11:
490 goes into 1300 2 times with a remainder of 320.
Use 2 as the next digit of our solution. 
Result so far: 27425.432
Subtracting 980 from 1300 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.

Moving on to step 12:
The number 490 fits into 3200 6 times, leaving a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 27425.4326
Subtracting 2940 from 3200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
If we divide 2600 by 490, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 27425.43265
If we take 2450 away from 2600, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
490 goes into 1500 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 27425.432653
If we subtract 1470 from 1500, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
490 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 27425.432653
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
490 can be fit into 3000 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 27425.43265306
If we take 2940 away from 3000, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 27425.43265306 and a remainder of 6e-08.
