We're dividing 77894811 by 490 
The aim is to understand the frequency of 490 in 77894811.

Going ahead to step 1:
If we divide 7 by 490, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 490

On to step 2:
The number 490 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 490

Moving on to step 3:
When dividing 778 by 490, we get 1 with a remainder of 288.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 490 from 778, we get 288.
Include the next digit (9) from the dividend after 288, then repeat: 2889 / 490

On to step 4:
2889 divided by 490 is 5 with a remainder of 439.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2450 from 2889 and we're left with 439.
Fetch the next digit (4) from the dividend, attach it to 439 and continue: 4394 / 490

Moving on to step 5:
490 goes into 4394 8 times with a remainder of 474.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Deduct 3920 from 4394 and we're left with 474.
Append the next digit (8) from the dividend to 474 and continue with: 4748 / 490

On to step 6:
4748 divided by 490 is 9 with a remainder of 338.
Put 9 as the next digit of the answer. 
Result so far: 1589.0
Subtracting 4410 from 4748 leaves us with 338.
Append the next digit (1) from the dividend to 338 and continue with: 3381 / 490

Going ahead to step 7:
If we divide 3381 by 490, we get 6 and a remainder of 441.
Use 6 as the next digit of our solution. 
Result so far: 15896.0
If we take 2940 away from 3381, we end up with 441.
Bring next digit (1) of the dividend behind the 441 and repeat the process: 4411 / 490

Step 8:
490 can be fit into 4411 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 158969.0
Subtracting 4410 from 4411 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
When dividing 10 by 490, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 158969.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 490, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 158969.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 158969.0 and a remainder of 0.1.
