Let's divide 43191300 by 585
The aim is to understand the frequency of 585 in 43191300.

Advancing to step 1:
When dividing 4 by 585, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 585

Moving on to step 2:
43 divided by 585 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 585

Going ahead to step 3:
When dividing 431 by 585, we get 0 with a remainder of 431.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 431 leaves us with 431.
Include the next digit (9) from the dividend after 431, then repeat: 4319 / 585

On to step 4:
When dividing 4319 by 585, we get 7 with a remainder of 224.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 4095 from 4319 to get 224.
Append the next digit (1) from the dividend to 224 and continue with: 2241 / 585

On to step 5:
When dividing 2241 by 585, we get 3 with a remainder of 486.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 486 after subtracting 1755 from 2241.
Take the next digit (3) from the dividend and append it to 486, then repeat: 4863 / 585

Let's proceed to step 6:
The number 585 fits into 4863 8 times, leaving a remainder of 183.
Put 8 as the next digit of the answer. 
Result so far: 738.0
Deduct 4680 from 4863 and we're left with 183.
Append the next digit (0) from the dividend to 183 and continue with: 1830 / 585

Advancing to step 7:
When dividing 1830 by 585, we get 3 with a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 7383.0
The remainder is 75 after subtracting 1755 from 1830.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 585

Step 8:
If we divide 750 by 585, we get 1 and a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 73831.0
Subtract 585 from 750 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 9:
When dividing 1650 by 585, we get 2 with a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 73831.2
The remainder is 480 after subtracting 1170 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 10:
The number 585 fits into 4800 8 times, leaving a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 73831.28
The remainder is 120 after subtracting 4680 from 4800.
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:
585 can be fit into 1200 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 73831.282
If we take 1170 away from 1200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
If we divide 300 by 585, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 73831.282
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 13:
3000 divided by 585 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 73831.28205
Subtract 2925 from 3000 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
585 goes into 750 1 times with a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 73831.282051
Subtracting 585 from 750 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 15:
The number 585 fits into 1650 2 times, leaving a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 73831.2820512
The remainder is 480 after subtracting 1170 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
If we divide 4800 by 585, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 73831.28205128
Deduct 4680 from 4800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 73831.28205128, with a leftover of 1.2e-07.
