Let's divide 83924531 by 580
The aim is to understand the frequency of 580 in 83924531.

On to step 1:
If we divide 8 by 580, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 580

Advancing to step 2:
580 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 580

Step 3:
The number 580 fits into 839 1 times, leaving a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 580 from 839 leaves us with 259.
Append the next digit (2) from the dividend to 259 and continue with: 2592 / 580

On to step 4:
580 can be fit into 2592 4 times, resulting in a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 2320 from 2592 leaves us with 272.
Append the next digit (4) from the dividend to 272 and continue with: 2724 / 580

Moving on to step 5:
If we divide 2724 by 580, we get 4 and a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 144.0
Deduct 2320 from 2724 and we're left with 404.
Fetch the next digit (5) from the dividend, attach it to 404 and continue: 4045 / 580

Step 6:
The number 580 fits into 4045 6 times, leaving a remainder of 565.
Put 6 as the next digit of the answer. 
Result so far: 1446.0
The remainder is 565 after subtracting 3480 from 4045.
Append the next digit (3) from the dividend to 565 and continue with: 5653 / 580

On to step 7:
580 goes into 5653 9 times with a remainder of 433.
Use 9 as the next digit of our solution. 
Result so far: 14469.0
Subtract 5220 from 5653 to get 433.
Include the next digit (1) from the dividend after 433, then repeat: 4331 / 580

Advancing to step 8:
580 can be fit into 4331 7 times, resulting in a remainder of 271.
Write down 7 as next digit of the result. 
Result so far: 144697.0
Subtract 4060 from 4331 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 9:
580 can be fit into 2710 4 times, resulting in a remainder of 390.
Put 4 as the next digit of the answer. 
Result so far: 144697.4
If we subtract 2320 from 2710, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
The number 580 fits into 3900 6 times, leaving a remainder of 420.
Use 6 as the next digit of our solution. 
Result so far: 144697.46
If we subtract 3480 from 3900, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
580 can be fit into 4200 7 times, resulting in a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 144697.467
Subtract 4060 from 4200 to 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.

Let's proceed to step 12:
If we divide 1400 by 580, we get 2 and a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 144697.4672
Subtract 1160 from 1400 to get 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 13:
When dividing 2400 by 580, we get 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 144697.46724
Subtracting 2320 from 2400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
The number 580 fits into 800 1 times, leaving a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 144697.467241
Subtract 580 from 800 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 15:
580 goes into 2200 3 times with a remainder of 460.
The number 3 becomes the next digit in our result. 
Result so far: 144697.4672413
If we subtract 1740 from 2200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 16:
If we divide 4600 by 580, we get 7 and a remainder of 540.
Put 7 as the next digit of the answer. 
Result so far: 144697.46724137
The remainder is 540 after subtracting 4060 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

In conclusion, the division gives 144697.46724137 with a balance of 5.4e-07.
