Let's divide 81500122 by 471
The aim is to understand the frequency of 471 in 81500122.

Going ahead to step 1:
471 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 471

Going ahead to step 2:
If we divide 81 by 471, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 471

Going ahead to step 3:
471 goes into 815 1 times with a remainder of 344.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 471 from 815 leaves us with 344.
Take the next digit (0) from the dividend and append it to 344, then repeat: 3440 / 471

On to step 4:
The number 471 fits into 3440 7 times, leaving a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 3297 from 3440 and we're left with 143.
Bring next digit (0) of the dividend behind the 143 and repeat the process: 1430 / 471

Moving on to step 5:
When dividing 1430 by 471, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 173.0
Subtract 1413 from 1430 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 471

Moving on to step 6:
When dividing 171 by 471, we get 0 with a remainder of 171.
The number 0 becomes the next digit in our result. 
Result so far: 1730.0
The remainder is 171 after subtracting 0 from 171.
Grab the next digit (2) from the dividend, add it to 171, then carry on: 1712 / 471

Let's proceed to step 7:
471 goes into 1712 3 times with a remainder of 299.
Record the quotient 3 as the next digit in the result. 
Result so far: 17303.0
If we take 1413 away from 1712, we end up with 299.
Include the next digit (2) from the dividend after 299, then repeat: 2992 / 471

Moving on to step 8:
471 can be fit into 2992 6 times, resulting in a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 173036.0
The remainder is 166 after subtracting 2826 from 2992.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 9:
When dividing 1660 by 471, we get 3 with a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 173036.3
If we subtract 1413 from 1660, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 10:
The number 471 fits into 2470 5 times, leaving a remainder of 115.
Write down 5 as next digit of the result. 
Result so far: 173036.35
If we subtract 2355 from 2470, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 11:
When dividing 1150 by 471, we get 2 with a remainder of 208.
The next digit of our result is 2. 
Result so far: 173036.352
If we subtract 942 from 1150, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
If we divide 2080 by 471, we get 4 and a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 173036.3524
If we subtract 1884 from 2080, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 13:
The number 471 fits into 1960 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 173036.35244
Subtracting 1884 from 1960 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 173036.35244, and the remainder is 7.6e-05.
