Let's divide 77703903 by 580
The aim is to understand the frequency of 580 in 77703903.

Going ahead to step 1:
The number 580 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 580

On to step 2:
When dividing 77 by 580, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 580

Advancing to step 3:
580 can be fit into 777 1 times, resulting in a remainder of 197.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 580 from 777 and we're left with 197.
Include the next digit (0) from the dividend after 197, then repeat: 1970 / 580

Going ahead to step 4:
1970 divided by 580 is 3 with a remainder of 230.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1740 from 1970, we get 230.
Bring next digit (3) of the dividend behind the 230 and repeat the process: 2303 / 580

Moving on to step 5:
If we divide 2303 by 580, we get 3 and a remainder of 563.
Use 3 as the next digit of our solution. 
Result so far: 133.0
If we take 1740 away from 2303, we end up with 563.
Append the next digit (9) from the dividend to 563 and continue with: 5639 / 580

Advancing to step 6:
580 goes into 5639 9 times with a remainder of 419.
The number 9 becomes the next digit in our result. 
Result so far: 1339.0
Subtracting 5220 from 5639 leaves us with 419.
Fetch the next digit (0) from the dividend, attach it to 419 and continue: 4190 / 580

Step 7:
4190 divided by 580 is 7 with a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 13397.0
Deduct 4060 from 4190 and we're left with 130.
Bring next digit (3) of the dividend behind the 130 and repeat the process: 1303 / 580

On to step 8:
1303 divided by 580 is 2 with a remainder of 143.
Put 2 as the next digit of the answer. 
Result so far: 133972.0
Subtracting 1160 from 1303 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 9:
580 goes into 1430 2 times with a remainder of 270.
The next digit of our result is 2. 
Result so far: 133972.2
Subtracting 1160 from 1430 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
If we divide 2700 by 580, we get 4 and a remainder of 380.
The next digit of our result is 4. 
Result so far: 133972.24
Deduct 2320 from 2700 and we're left 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.

Going ahead to step 11:
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: 133972.246
If we subtract 3480 from 3800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
When dividing 3200 by 580, we get 5 with a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 133972.2465
Deduct 2900 from 3200 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 13:
580 can be fit into 3000 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 133972.24655
Deduct 2900 from 3000 and we're left 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.

Our division results in 133972.24655 with a remaining 0.0001.
