78855423 divided by 571 
The aim is to understand the frequency of 571 in 78855423.

On to step 1:
571 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 571

Let's proceed to step 2:
The number 571 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 571

Advancing to step 3:
571 goes into 788 1 times with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 571 from 788 to get 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 571

Step 4:
571 goes into 2175 3 times with a remainder of 462.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1713 away from 2175, we end up with 462.
Bring next digit (5) of the dividend behind the 462 and repeat the process: 4625 / 571

Moving on to step 5:
When dividing 4625 by 571, we get 8 with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 4568 from 4625, we get 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 571

Going ahead to step 6:
The number 571 fits into 574 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1381.0
Subtract 571 from 574 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 571

Going ahead to step 7:
If we divide 32 by 571, we get 0 and a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 13810.0
Deduct 0 from 32 and we're left with 32.
Fetch the next digit (3) from the dividend, attach it to 32 and continue: 323 / 571

Let's proceed to step 8:
571 goes into 323 0 times with a remainder of 323.
Write down 0 as next digit of the result. 
Result so far: 138100.0
If we take 0 away from 323, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 9:
When dividing 3230 by 571, we get 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 138100.5
If we subtract 2855 from 3230, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
571 can be fit into 3750 6 times, resulting in a remainder of 324.
Use 6 as the next digit of our solution. 
Result so far: 138100.56
Subtracting 3426 from 3750 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 11:
If we divide 3240 by 571, we get 5 and a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 138100.565
If we take 2855 away from 3240, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 12:
571 goes into 3850 6 times with a remainder of 424.
The number 6 becomes the next digit in our result. 
Result so far: 138100.5656
Subtracting 3426 from 3850 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 13:
4240 divided by 571 is 7 with a remainder of 243.
Use 7 as the next digit of our solution. 
Result so far: 138100.56567
Deduct 3997 from 4240 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 14:
If we divide 2430 by 571, we get 4 and a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 138100.565674
Subtract 2284 from 2430 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 15:
If we divide 1460 by 571, we get 2 and a remainder of 318.
The next digit of our result is 2. 
Result so far: 138100.5656742
If we take 1142 away from 1460, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Going ahead to step 16:
The number 571 fits into 3180 5 times, leaving a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 138100.56567425
If we subtract 2855 from 3180, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

The final outcome is 138100.56567425, with a leftover of 3.25e-07.
