We're dividing 45725778 by 871 
The aim is to understand the frequency of 871 in 45725778.

Advancing to step 1:
If we divide 4 by 871, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 871

Going ahead to step 2:
45 divided by 871 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 871

Step 3:
457 divided by 871 is 0 with a remainder of 457.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 457, we end up with 457.
Bring next digit (2) of the dividend behind the 457 and repeat the process: 4572 / 871

On to step 4:
If we divide 4572 by 871, we get 5 and a remainder of 217.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4355 from 4572, we get 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 871

Step 5:
When dividing 2175 by 871, we get 2 with a remainder of 433.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 1742 away from 2175, we end up with 433.
Fetch the next digit (7) from the dividend, attach it to 433 and continue: 4337 / 871

Advancing to step 6:
If we divide 4337 by 871, we get 4 and a remainder of 853.
Write down 4 as next digit of the result. 
Result so far: 524.0
Subtracting 3484 from 4337 leaves us with 853.
Append the next digit (7) from the dividend to 853 and continue with: 8537 / 871

Let's proceed to step 7:
If we divide 8537 by 871, we get 9 and a remainder of 698.
Record the quotient 9 as the next digit in the result. 
Result so far: 5249.0
If we subtract 7839 from 8537, we get 698.
Fetch the next digit (8) from the dividend, attach it to 698 and continue: 6988 / 871

Moving on to step 8:
When dividing 6988 by 871, we get 8 with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 52498.0
The remainder is 20 after subtracting 6968 from 6988.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 871 is 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 52498.0
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
The number 871 fits into 2000 2 times, leaving a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 52498.02
The remainder is 258 after subtracting 1742 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 11:
The number 871 fits into 2580 2 times, leaving a remainder of 838.
Record the quotient 2 as the next digit in the result. 
Result so far: 52498.022
Subtract 1742 from 2580 to get 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

After the division, we end up with 52498.022 and a remainder of 0.0838.
