We're dividing 81689229 by 471 
The aim is to understand the frequency of 471 in 81689229.

Step 1:
If we divide 8 by 471, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 471

Moving on to step 2:
If we divide 81 by 471, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 471

Advancing to step 3:
816 divided by 471 is 1 with a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 471 from 816 and we're left with 345.
Grab the next digit (8) from the dividend, add it to 345, then carry on: 3458 / 471

Let's proceed to step 4:
471 can be fit into 3458 7 times, resulting in a remainder of 161.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 161 after subtracting 3297 from 3458.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 471

Step 5:
When dividing 1619 by 471, we get 3 with a remainder of 206.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Deduct 1413 from 1619 and we're left with 206.
Fetch the next digit (2) from the dividend, attach it to 206 and continue: 2062 / 471

Going ahead to step 6:
The number 471 fits into 2062 4 times, leaving a remainder of 178.
Put 4 as the next digit of the answer. 
Result so far: 1734.0
Deduct 1884 from 2062 and we're left with 178.
Fetch the next digit (2) from the dividend, attach it to 178 and continue: 1782 / 471

Step 7:
When dividing 1782 by 471, we get 3 with a remainder of 369.
The number 3 becomes the next digit in our result. 
Result so far: 17343.0
Subtract 1413 from 1782 to get 369.
Include the next digit (9) from the dividend after 369, then repeat: 3699 / 471

Step 8:
471 goes into 3699 7 times with a remainder of 402.
Use 7 as the next digit of our solution. 
Result so far: 173437.0
If we subtract 3297 from 3699, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 9:
If we divide 4020 by 471, we get 8 and a remainder of 252.
The next digit of our result is 8. 
Result so far: 173437.8
Subtract 3768 from 4020 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 10:
The number 471 fits into 2520 5 times, leaving a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 173437.85
Deduct 2355 from 2520 and we're left 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.

On to step 11:
When dividing 1650 by 471, we get 3 with a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 173437.853
Deduct 1413 from 1650 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 12:
If we divide 2370 by 471, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 173437.8535
Subtract 2355 from 2370 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
The number 471 fits into 150 0 times, leaving a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 173437.8535
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
1500 divided by 471 is 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 173437.853503
Deduct 1413 from 1500 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 15:
If we divide 870 by 471, we get 1 and a remainder of 399.
Record the quotient 1 as the next digit in the result. 
Result so far: 173437.8535031
Subtracting 471 from 870 leaves us with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 16:
3990 divided by 471 is 8 with a remainder of 222.
The next digit of our result is 8. 
Result so far: 173437.85350318
Deduct 3768 from 3990 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final outcome is 173437.85350318, with a leftover of 2.22e-07.
