Let's divide 77974505 by 580
The aim is to understand the frequency of 580 in 77974505.

Moving on to step 1:
580 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 580

Advancing to step 2:
When dividing 77 by 580, we get 0 with 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 (9) from the dividend and append it to 77, then repeat: 779 / 580

Step 3:
When dividing 779 by 580, we get 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 580 from 779 leaves us with 199.
Include the next digit (7) from the dividend after 199, then repeat: 1997 / 580

On to step 4:
580 goes into 1997 3 times with a remainder of 257.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1740 from 1997 leaves us with 257.
Grab the next digit (4) from the dividend, add it to 257, then carry on: 2574 / 580

Moving on to step 5:
580 can be fit into 2574 4 times, resulting in a remainder of 254.
The next digit of our result is 4. 
Result so far: 134.0
If we subtract 2320 from 2574, we get 254.
Append the next digit (5) from the dividend to 254 and continue with: 2545 / 580

Advancing to step 6:
2545 divided by 580 is 4 with a remainder of 225.
Write down 4 as next digit of the result. 
Result so far: 1344.0
If we take 2320 away from 2545, we end up with 225.
Fetch the next digit (0) from the dividend, attach it to 225 and continue: 2250 / 580

On to step 7:
When dividing 2250 by 580, we get 3 with a remainder of 510.
Put 3 as the next digit of the answer. 
Result so far: 13443.0
Subtracting 1740 from 2250 leaves us with 510.
Bring next digit (5) of the dividend behind the 510 and repeat the process: 5105 / 580

Going ahead to step 8:
If we divide 5105 by 580, we get 8 and a remainder of 465.
Record the quotient 8 as the next digit in the result. 
Result so far: 134438.0
If we take 4640 away from 5105, we end up with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Let's proceed to step 9:
If we divide 4650 by 580, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 134438.8
Deduct 4640 from 4650 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
580 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 134438.8
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
580 can be fit into 1000 1 times, resulting in a remainder of 420.
Record the quotient 1 as the next digit in the result. 
Result so far: 134438.801
Subtracting 580 from 1000 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
The number 580 fits into 4200 7 times, leaving a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 134438.8017
If we subtract 4060 from 4200, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 13:
580 can be fit into 1400 2 times, resulting in a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 134438.80172
Deduct 1160 from 1400 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
If we divide 2400 by 580, we get 4 and a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 134438.801724
The remainder is 80 after subtracting 2320 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
If we divide 800 by 580, we get 1 and a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 134438.8017241
The remainder is 220 after subtracting 580 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
The number 580 fits into 2200 3 times, leaving a remainder of 460.
Write down 3 as next digit of the result. 
Result so far: 134438.80172413
The remainder is 460 after subtracting 1740 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The final result is 134438.80172413 with a remainder of 4.6e-07.
