We're dividing 81816039 by 472 
The aim is to understand the frequency of 472 in 81816039.

Advancing to step 1:
472 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 472

Let's proceed to step 2:
When dividing 81 by 472, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 472

Step 3:
472 can be fit into 818 1 times, resulting in a remainder of 346.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 472 away from 818, we end up with 346.
Append the next digit (1) from the dividend to 346 and continue with: 3461 / 472

Advancing to step 4:
The number 472 fits into 3461 7 times, leaving a remainder of 157.
The next digit of our result is 7. 
Result so far: 17.0
If we take 3304 away from 3461, we end up with 157.
Append the next digit (6) from the dividend to 157 and continue with: 1576 / 472

Going ahead to step 5:
472 goes into 1576 3 times with a remainder of 160.
The next digit of our result is 3. 
Result so far: 173.0
If we take 1416 away from 1576, we end up with 160.
Bring next digit (0) of the dividend behind the 160 and repeat the process: 1600 / 472

Going ahead to step 6:
When dividing 1600 by 472, we get 3 with a remainder of 184.
The number 3 becomes the next digit in our result. 
Result so far: 1733.0
Subtracting 1416 from 1600 leaves us with 184.
Grab the next digit (3) from the dividend, add it to 184, then carry on: 1843 / 472

Going ahead to step 7:
472 can be fit into 1843 3 times, resulting in a remainder of 427.
The next digit of our result is 3. 
Result so far: 17333.0
Deduct 1416 from 1843 and we're left with 427.
Bring next digit (9) of the dividend behind the 427 and repeat the process: 4279 / 472

Step 8:
The number 472 fits into 4279 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 173339.0
Subtracting 4248 from 4279 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
472 goes into 310 0 times with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 173339.0
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
472 can be fit into 3100 6 times, resulting in a remainder of 268.
Put 6 as the next digit of the answer. 
Result so far: 173339.06
Deduct 2832 from 3100 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 11:
The number 472 fits into 2680 5 times, leaving a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 173339.065
Deduct 2360 from 2680 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 12:
When dividing 3200 by 472, we get 6 with a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 173339.0656
Subtract 2832 from 3200 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 13:
If we divide 3680 by 472, we get 7 and a remainder of 376.
The number 7 becomes the next digit in our result. 
Result so far: 173339.06567
The remainder is 376 after subtracting 3304 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 14:
472 goes into 3760 7 times with a remainder of 456.
Write down 7 as next digit of the result. 
Result so far: 173339.065677
If we subtract 3304 from 3760, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

In conclusion, the division gives 173339.065677 with a balance of 4.56e-05.
