48120292 ÷ 490 
The aim is to understand the frequency of 490 in 48120292.

Going ahead to step 1:
When dividing 4 by 490, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 490

Step 2:
48 divided by 490 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 490

Moving on to step 3:
If we divide 481 by 490, we get 0 and a remainder of 481.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 481 and we're left with 481.
Grab the next digit (2) from the dividend, add it to 481, then carry on: 4812 / 490

Moving on to step 4:
When dividing 4812 by 490, we get 9 with a remainder of 402.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 4410 from 4812 and we're left with 402.
Grab the next digit (0) from the dividend, add it to 402, then carry on: 4020 / 490

Moving on to step 5:
4020 divided by 490 is 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Deduct 3920 from 4020 and we're left with 100.
Grab the next digit (2) from the dividend, add it to 100, then carry on: 1002 / 490

Let's proceed to step 6:
490 can be fit into 1002 2 times, resulting in a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 982.0
The remainder is 22 after subtracting 980 from 1002.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 490

Advancing to step 7:
229 divided by 490 is 0 with a remainder of 229.
Write down 0 as next digit of the result. 
Result so far: 9820.0
The remainder is 229 after subtracting 0 from 229.
Grab the next digit (2) from the dividend, add it to 229, then carry on: 2292 / 490

Going ahead to step 8:
490 goes into 2292 4 times with a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 98204.0
Deduct 1960 from 2292 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 9:
490 goes into 3320 6 times with a remainder of 380.
Record the quotient 6 as the next digit in the result. 
Result so far: 98204.6
If we subtract 2940 from 3320, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 10:
490 goes into 3800 7 times with a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 98204.67
Subtract 3430 from 3800 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
3700 divided by 490 is 7 with a remainder of 270.
Record the quotient 7 as the next digit in the result. 
Result so far: 98204.677
If we subtract 3430 from 3700, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final result is 98204.677 with a remainder of 0.027.
