13447872 ÷ 473 
The aim is to understand the frequency of 473 in 13447872.

Step 1:
473 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 473

Step 2:
The number 473 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 473

On to step 3:
The number 473 fits into 134 0 times, leaving a remainder of 134.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 134 leaves us with 134.
Bring next digit (4) of the dividend behind the 134 and repeat the process: 1344 / 473

Let's proceed to step 4:
When dividing 1344 by 473, we get 2 with a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 946 from 1344 to get 398.
Include the next digit (7) from the dividend after 398, then repeat: 3987 / 473

Step 5:
473 goes into 3987 8 times with a remainder of 203.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 203 after subtracting 3784 from 3987.
Take the next digit (8) from the dividend and append it to 203, then repeat: 2038 / 473

Moving on to step 6:
The number 473 fits into 2038 4 times, leaving a remainder of 146.
The next digit of our result is 4. 
Result so far: 284.0
The remainder is 146 after subtracting 1892 from 2038.
Fetch the next digit (7) from the dividend, attach it to 146 and continue: 1467 / 473

Let's proceed to step 7:
When dividing 1467 by 473, we get 3 with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 2843.0
The remainder is 48 after subtracting 1419 from 1467.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 473

Moving on to step 8:
If we divide 482 by 473, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 28431.0
The remainder is 9 after subtracting 473 from 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
473 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 28431.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
473 can be fit into 900 1 times, resulting in a remainder of 427.
Record the quotient 1 as the next digit in the result. 
Result so far: 28431.01
Deduct 473 from 900 and we're left 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.

On to step 11:
473 goes into 4270 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 28431.019
Deduct 4257 from 4270 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
473 goes into 130 0 times with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 28431.019
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
473 goes into 1300 2 times with a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 28431.01902
The remainder is 354 after subtracting 946 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 14:
If we divide 3540 by 473, we get 7 and a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 28431.019027
The remainder is 229 after subtracting 3311 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 15:
473 goes into 2290 4 times with a remainder of 398.
Put 4 as the next digit of the answer. 
Result so far: 28431.0190274
Subtract 1892 from 2290 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 16:
473 goes into 3980 8 times with a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 28431.01902748
The remainder is 196 after subtracting 3784 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The quotient of the division is 28431.01902748, and the remainder is 1.96e-07.
