We look at the division of 57581091 by 490 
The aim is to understand the frequency of 490 in 57581091.

On to step 1:
When dividing 5 by 490, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 490

Let's proceed to step 2:
490 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 490

Moving on to step 3:
490 can be fit into 575 1 times, resulting in a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 490 from 575 leaves us with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 490

Moving on to step 4:
490 can be fit into 858 1 times, resulting in a remainder of 368.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 490 away from 858, we end up with 368.
Fetch the next digit (1) from the dividend, attach it to 368 and continue: 3681 / 490

Advancing to step 5:
The number 490 fits into 3681 7 times, leaving a remainder of 251.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 251 after subtracting 3430 from 3681.
Grab the next digit (0) from the dividend, add it to 251, then carry on: 2510 / 490

Going ahead to step 6:
When dividing 2510 by 490, we get 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 1175.0
If we subtract 2450 from 2510, we get 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 490

On to step 7:
609 divided by 490 is 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 11751.0
The remainder is 119 after subtracting 490 from 609.
Take the next digit (1) from the dividend and append it to 119, then repeat: 1191 / 490

Going ahead to step 8:
490 goes into 1191 2 times with a remainder of 211.
The number 2 becomes the next digit in our result. 
Result so far: 117512.0
Subtracting 980 from 1191 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 9:
If we divide 2110 by 490, we get 4 and a remainder of 150.
Put 4 as the next digit of the answer. 
Result so far: 117512.4
Deduct 1960 from 2110 and we're left 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.

Moving on to step 10:
490 can be fit into 1500 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 117512.43
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 11:
The number 490 fits into 300 0 times, leaving a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 117512.43
If we subtract 0 from 300, we 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.

Let's proceed to step 12:
490 can be fit into 3000 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 117512.4306
Subtracting 2940 from 3000 leaves us 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.

Moving on to step 13:
If we divide 600 by 490, we get 1 and a remainder of 110.
Write down 1 as next digit of the result. 
Result so far: 117512.43061
Deduct 490 from 600 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 14:
490 goes into 1100 2 times with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 117512.430612
If we subtract 980 from 1100, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
490 goes into 1200 2 times with a remainder of 220.
The next digit of our result is 2. 
Result so far: 117512.4306122
The remainder is 220 after subtracting 980 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 117512.4306122 and a remainder of 2.2e-06.
