43697786 divided by 580 
The aim is to understand the frequency of 580 in 43697786.

Step 1:
If we divide 4 by 580, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 580

Moving on to step 2:
580 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 580

Step 3:
436 divided by 580 is 0 with a remainder of 436.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 436 and we're left with 436.
Fetch the next digit (9) from the dividend, attach it to 436 and continue: 4369 / 580

Step 4:
580 goes into 4369 7 times with a remainder of 309.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 309 after subtracting 4060 from 4369.
Grab the next digit (7) from the dividend, add it to 309, then carry on: 3097 / 580

Let's proceed to step 5:
If we divide 3097 by 580, we get 5 and a remainder of 197.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Deduct 2900 from 3097 and we're left with 197.
Bring next digit (7) of the dividend behind the 197 and repeat the process: 1977 / 580

Step 6:
580 goes into 1977 3 times with a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 753.0
Subtract 1740 from 1977 to get 237.
Grab the next digit (8) from the dividend, add it to 237, then carry on: 2378 / 580

Going ahead to step 7:
If we divide 2378 by 580, we get 4 and a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 7534.0
If we subtract 2320 from 2378, we get 58.
Append the next digit (6) from the dividend to 58 and continue with: 586 / 580

On to step 8:
The number 580 fits into 586 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 75341.0
If we subtract 580 from 586, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 580 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 75341.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
If we divide 600 by 580, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 75341.01
If we subtract 580 from 600, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
The number 580 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 75341.01
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
When dividing 2000 by 580, we get 3 with a remainder of 260.
Put 3 as the next digit of the answer. 
Result so far: 75341.0103
Deduct 1740 from 2000 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 13:
The number 580 fits into 2600 4 times, leaving a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 75341.01034
Subtract 2320 from 2600 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
580 can be fit into 2800 4 times, resulting in a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 75341.010344
The remainder is 480 after subtracting 2320 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 75341.010344 with a balance of 4.8e-05.
