We look at the division of 77976422 by 490 
We want to divide 77976422 by 490.

Let's proceed to step 1:
490 goes into 7 0 times with 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.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 490

Going ahead to step 2:
490 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (9) from the dividend after 77, then repeat: 779 / 490

Moving on to step 3:
490 can be fit into 779 1 times, resulting in a remainder of 289.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 289 after subtracting 490 from 779.
Include the next digit (7) from the dividend after 289, then repeat: 2897 / 490

Advancing to step 4:
When dividing 2897 by 490, we get 5 with a remainder of 447.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2450 away from 2897, we end up with 447.
Take the next digit (6) from the dividend and append it to 447, then repeat: 4476 / 490

Going ahead to step 5:
490 can be fit into 4476 9 times, resulting in a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Deduct 4410 from 4476 and we're left with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 490

Going ahead to step 6:
The number 490 fits into 664 1 times, leaving a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 1591.0
If we subtract 490 from 664, we get 174.
Append the next digit (2) from the dividend to 174 and continue with: 1742 / 490

Advancing to step 7:
If we divide 1742 by 490, we get 3 and a remainder of 272.
The next digit of our result is 3. 
Result so far: 15913.0
If we subtract 1470 from 1742, we get 272.
Append the next digit (2) from the dividend to 272 and continue with: 2722 / 490

Advancing to step 8:
If we divide 2722 by 490, we get 5 and a remainder of 272.
Put 5 as the next digit of the answer. 
Result so far: 159135.0
If we take 2450 away from 2722, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 9:
490 can be fit into 2720 5 times, resulting in a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 159135.5
Subtract 2450 from 2720 to 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.

On to step 10:
When dividing 2700 by 490, we get 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 159135.55
If we subtract 2450 from 2700, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

In conclusion, the division gives 159135.55 with a balance of 0.25.
