We look at the division of 72431650 by 471 
The aim is to understand the frequency of 471 in 72431650.

Advancing to step 1:
471 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 471

Going ahead to step 2:
When dividing 72 by 471, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (4) of the dividend behind the 72 and repeat the process: 724 / 471

Advancing to step 3:
When dividing 724 by 471, we get 1 with a remainder of 253.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 471 from 724 and we're left with 253.
Bring next digit (3) of the dividend behind the 253 and repeat the process: 2533 / 471

On to step 4:
471 can be fit into 2533 5 times, resulting in a remainder of 178.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 2355 from 2533 and we're left with 178.
Append the next digit (1) from the dividend to 178 and continue with: 1781 / 471

On to step 5:
The number 471 fits into 1781 3 times, leaving a remainder of 368.
Put 3 as the next digit of the answer. 
Result so far: 153.0
Subtracting 1413 from 1781 leaves us with 368.
Append the next digit (6) from the dividend to 368 and continue with: 3686 / 471

Step 6:
3686 divided by 471 is 7 with a remainder of 389.
Record the quotient 7 as the next digit in the result. 
Result so far: 1537.0
If we subtract 3297 from 3686, we get 389.
Grab the next digit (5) from the dividend, add it to 389, then carry on: 3895 / 471

Step 7:
3895 divided by 471 is 8 with a remainder of 127.
Write down 8 as next digit of the result. 
Result so far: 15378.0
If we subtract 3768 from 3895, we get 127.
Grab the next digit (0) from the dividend, add it to 127, then carry on: 1270 / 471

Going ahead to step 8:
The number 471 fits into 1270 2 times, leaving a remainder of 328.
Write down 2 as next digit of the result. 
Result so far: 153782.0
Subtracting 942 from 1270 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 9:
The number 471 fits into 3280 6 times, leaving a remainder of 454.
Put 6 as the next digit of the answer. 
Result so far: 153782.6
If we subtract 2826 from 3280, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 10:
471 goes into 4540 9 times with a remainder of 301.
Record the quotient 9 as the next digit in the result. 
Result so far: 153782.69
Subtract 4239 from 4540 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 11:
471 can be fit into 3010 6 times, resulting in a remainder of 184.
The next digit of our result is 6. 
Result so far: 153782.696
If we take 2826 away from 3010, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
If we divide 1840 by 471, we get 3 and a remainder of 427.
Use 3 as the next digit of our solution. 
Result so far: 153782.6963
If we take 1413 away from 1840, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Let's proceed to step 13:
When dividing 4270 by 471, we get 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 153782.69639
If we subtract 4239 from 4270, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
When dividing 310 by 471, we get 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 153782.69639
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 15:
3100 divided by 471 is 6 with a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 153782.6963906
If we take 2826 away from 3100, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 16:
471 goes into 2740 5 times with a remainder of 385.
The next digit of our result is 5. 
Result so far: 153782.69639065
Deduct 2355 from 2740 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

In conclusion, the division gives 153782.69639065 with a balance of 3.85e-07.
