74508402 ÷ 571 
The aim is to understand the frequency of 571 in 74508402.

Let's proceed to step 1:
The number 571 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 571

On to step 2:
74 divided by 571 is 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 571

Moving on to step 3:
The number 571 fits into 745 1 times, leaving a remainder of 174.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 571 from 745 leaves us with 174.
Take the next digit (0) from the dividend and append it to 174, then repeat: 1740 / 571

On to step 4:
When dividing 1740 by 571, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1713 from 1740, we get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 571

Moving on to step 5:
When dividing 278 by 571, we get 0 with a remainder of 278.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtract 0 from 278 to get 278.
Append the next digit (4) from the dividend to 278 and continue with: 2784 / 571

Step 6:
2784 divided by 571 is 4 with a remainder of 500.
The next digit of our result is 4. 
Result so far: 1304.0
Subtracting 2284 from 2784 leaves us with 500.
Fetch the next digit (0) from the dividend, attach it to 500 and continue: 5000 / 571

Let's proceed to step 7:
571 can be fit into 5000 8 times, resulting in a remainder of 432.
Use 8 as the next digit of our solution. 
Result so far: 13048.0
If we subtract 4568 from 5000, we get 432.
Grab the next digit (2) from the dividend, add it to 432, then carry on: 4322 / 571

Step 8:
571 can be fit into 4322 7 times, resulting in a remainder of 325.
The number 7 becomes the next digit in our result. 
Result so far: 130487.0
Subtract 3997 from 4322 to 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.

Advancing to step 9:
The number 571 fits into 3250 5 times, leaving a remainder of 395.
Write down 5 as next digit of the result. 
Result so far: 130487.5
The remainder is 395 after subtracting 2855 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 10:
When dividing 3950 by 571, we get 6 with a remainder of 524.
Put 6 as the next digit of the answer. 
Result so far: 130487.56
Subtract 3426 from 3950 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 11:
When dividing 5240 by 571, we get 9 with a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 130487.569
If we take 5139 away from 5240, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 12:
571 can be fit into 1010 1 times, resulting in a remainder of 439.
Put 1 as the next digit of the answer. 
Result so far: 130487.5691
If we subtract 571 from 1010, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 13:
The number 571 fits into 4390 7 times, leaving a remainder of 393.
The number 7 becomes the next digit in our result. 
Result so far: 130487.56917
Deduct 3997 from 4390 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 14:
3930 divided by 571 is 6 with a remainder of 504.
Use 6 as the next digit of our solution. 
Result so far: 130487.569176
Subtract 3426 from 3930 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 15:
571 can be fit into 5040 8 times, resulting in a remainder of 472.
Put 8 as the next digit of the answer. 
Result so far: 130487.5691768
Subtracting 4568 from 5040 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 16:
When dividing 4720 by 571, we get 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 130487.56917688
The remainder is 152 after subtracting 4568 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final outcome is 130487.56917688, with a leftover of 1.52e-07.
