25575382 divided by 490 
The aim is to understand the frequency of 490 in 25575382.

Step 1:
When dividing 2 by 490, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 490

Advancing to step 2:
25 divided by 490 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 490

Going ahead to step 3:
490 can be fit into 255 0 times, resulting in a remainder of 255.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 255 to get 255.
Take the next digit (7) from the dividend and append it to 255, then repeat: 2557 / 490

Moving on to step 4:
2557 divided by 490 is 5 with a remainder of 107.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2450 from 2557 and we're left with 107.
Grab the next digit (5) from the dividend, add it to 107, then carry on: 1075 / 490

Moving on to step 5:
The number 490 fits into 1075 2 times, leaving a remainder of 95.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Deduct 980 from 1075 and we're left with 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 490

Going ahead to step 6:
490 goes into 953 1 times with a remainder of 463.
Use 1 as the next digit of our solution. 
Result so far: 521.0
If we take 490 away from 953, we end up with 463.
Take the next digit (8) from the dividend and append it to 463, then repeat: 4638 / 490

On to step 7:
If we divide 4638 by 490, we get 9 and a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 5219.0
Subtracting 4410 from 4638 leaves us with 228.
Fetch the next digit (2) from the dividend, attach it to 228 and continue: 2282 / 490

Step 8:
If we divide 2282 by 490, we get 4 and a remainder of 322.
Use 4 as the next digit of our solution. 
Result so far: 52194.0
Subtracting 1960 from 2282 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 9:
The number 490 fits into 3220 6 times, leaving a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 52194.6
Subtract 2940 from 3220 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
The number 490 fits into 2800 5 times, leaving a remainder of 350.
The next digit of our result is 5. 
Result so far: 52194.65
Subtracting 2450 from 2800 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
490 can be fit into 3500 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 52194.657
Subtracting 3430 from 3500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
700 divided by 490 is 1 with a remainder of 210.
The next digit of our result is 1. 
Result so far: 52194.6571
Subtract 490 from 700 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 13:
490 can be fit into 2100 4 times, resulting in a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 52194.65714
Subtracting 1960 from 2100 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 14:
If we divide 1400 by 490, we get 2 and a remainder of 420.
Use 2 as the next digit of our solution. 
Result so far: 52194.657142
The remainder is 420 after subtracting 980 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 15:
490 can be fit into 4200 8 times, resulting in a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 52194.6571428
The remainder is 280 after subtracting 3920 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 16:
490 goes into 2800 5 times with a remainder of 350.
The next digit of our result is 5. 
Result so far: 52194.65714285
If we take 2450 away from 2800, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The quotient of the division is 52194.65714285, and the remainder is 3.5e-07.
