77655250 ÷ 580 
Our goal is to divide 77655250 by 580.

Going ahead to step 1:
When dividing 7 by 580, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 580

Going ahead to step 2:
When dividing 77 by 580, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 580

Moving on to step 3:
776 divided by 580 is 1 with a remainder of 196.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 580 from 776, we get 196.
Take the next digit (5) from the dividend and append it to 196, then repeat: 1965 / 580

Let's proceed to step 4:
580 can be fit into 1965 3 times, resulting in a remainder of 225.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 1740 from 1965 to get 225.
Include the next digit (5) from the dividend after 225, then repeat: 2255 / 580

On to step 5:
If we divide 2255 by 580, we get 3 and a remainder of 515.
The next digit of our result is 3. 
Result so far: 133.0
Deduct 1740 from 2255 and we're left with 515.
Grab the next digit (2) from the dividend, add it to 515, then carry on: 5152 / 580

Going ahead to step 6:
The number 580 fits into 5152 8 times, leaving a remainder of 512.
Put 8 as the next digit of the answer. 
Result so far: 1338.0
If we take 4640 away from 5152, we end up with 512.
Include the next digit (5) from the dividend after 512, then repeat: 5125 / 580

Going ahead to step 7:
5125 divided by 580 is 8 with a remainder of 485.
Put 8 as the next digit of the answer. 
Result so far: 13388.0
Deduct 4640 from 5125 and we're left with 485.
Include the next digit (0) from the dividend after 485, then repeat: 4850 / 580

Step 8:
The number 580 fits into 4850 8 times, leaving a remainder of 210.
The number 8 becomes the next digit in our result. 
Result so far: 133888.0
Deduct 4640 from 4850 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 9:
The number 580 fits into 2100 3 times, leaving a remainder of 360.
The next digit of our result is 3. 
Result so far: 133888.3
Subtracting 1740 from 2100 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 580, we get 6 and a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 133888.36
If we subtract 3480 from 3600, 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.

Going ahead to step 11:
If we divide 1200 by 580, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 133888.362
If we subtract 1160 from 1200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
If we divide 400 by 580, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 133888.362
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
580 can be fit into 4000 6 times, resulting in a remainder of 520.
Record the quotient 6 as the next digit in the result. 
Result so far: 133888.36206
Deduct 3480 from 4000 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 14:
If we divide 5200 by 580, we get 8 and a remainder of 560.
Write down 8 as next digit of the result. 
Result so far: 133888.362068
Deduct 4640 from 5200 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 15:
The number 580 fits into 5600 9 times, leaving a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 133888.3620689
If we take 5220 away from 5600, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 16:
When dividing 3800 by 580, we get 6 with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 133888.36206896
Subtracting 3480 from 3800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

After the division, we end up with 133888.36206896 and a remainder of 3.2e-07.
