We're dividing 90163505 by 490 
The aim is to understand the frequency of 490 in 90163505.

Going ahead to step 1:
When dividing 9 by 490, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 490

Advancing to step 2:
490 can be fit into 90 0 times, resulting in a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Append the next digit (1) from the dividend to 90 and continue with: 901 / 490

On to step 3:
901 divided by 490 is 1 with a remainder of 411.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 490 from 901 leaves us with 411.
Bring next digit (6) of the dividend behind the 411 and repeat the process: 4116 / 490

Going ahead to step 4:
If we divide 4116 by 490, we get 8 and a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 3920 from 4116 leaves us with 196.
Append the next digit (3) from the dividend to 196 and continue with: 1963 / 490

Moving on to step 5:
The number 490 fits into 1963 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
Subtracting 1960 from 1963 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 490

Advancing to step 6:
The number 490 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 1840.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 490

Moving on to step 7:
If we divide 350 by 490, we get 0 and a remainder of 350.
The next digit of our result is 0. 
Result so far: 18400.0
Subtract 0 from 350 to get 350.
Append the next digit (5) from the dividend to 350 and continue with: 3505 / 490

Going ahead to step 8:
490 can be fit into 3505 7 times, resulting in a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 184007.0
If we subtract 3430 from 3505, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
The number 490 fits into 750 1 times, leaving a remainder of 260.
The next digit of our result is 1. 
Result so far: 184007.1
If we take 490 away from 750, we end up 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.

Moving on to step 10:
If we divide 2600 by 490, we get 5 and a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 184007.15
If we subtract 2450 from 2600, we get 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 11:
1500 divided by 490 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 184007.153
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.

Going ahead to step 12:
300 divided by 490 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 184007.153
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 13:
The number 490 fits into 3000 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 184007.15306
The remainder is 60 after subtracting 2940 from 3000.
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 14:
If we divide 600 by 490, we get 1 and a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 184007.153061
Subtracting 490 from 600 leaves us 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.

On to step 15:
1100 divided by 490 is 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 184007.1530612
If we take 980 away from 1100, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
490 can be fit into 1200 2 times, resulting in a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 184007.15306122
Deduct 980 from 1200 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 184007.15306122 with a balance of 2.2e-07.
