We look at the division of 18921145 by 472 
The aim is to understand the frequency of 472 in 18921145.

Going ahead to step 1:
1 divided by 472 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 472

Advancing to step 2:
472 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 472

Moving on to step 3:
If we divide 189 by 472, we get 0 and a remainder of 189.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 189 to get 189.
Grab the next digit (2) from the dividend, add it to 189, then carry on: 1892 / 472

Moving on to step 4:
472 goes into 1892 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1888 away from 1892, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 472

Step 5:
When dividing 41 by 472, we get 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 472

Going ahead to step 6:
411 divided by 472 is 0 with a remainder of 411.
The next digit of our result is 0. 
Result so far: 400.0
Subtract 0 from 411 to get 411.
Bring next digit (4) of the dividend behind the 411 and repeat the process: 4114 / 472

Advancing to step 7:
4114 divided by 472 is 8 with a remainder of 338.
The next digit of our result is 8. 
Result so far: 4008.0
Subtract 3776 from 4114 to get 338.
Take the next digit (5) from the dividend and append it to 338, then repeat: 3385 / 472

Let's proceed to step 8:
The number 472 fits into 3385 7 times, leaving a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 40087.0
The remainder is 81 after subtracting 3304 from 3385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
The number 472 fits into 810 1 times, leaving a remainder of 338.
Use 1 as the next digit of our solution. 
Result so far: 40087.1
If we take 472 away from 810, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
If we divide 3380 by 472, we get 7 and a remainder of 76.
The next digit of our result is 7. 
Result so far: 40087.17
The remainder is 76 after subtracting 3304 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
472 can be fit into 760 1 times, resulting in a remainder of 288.
The next digit of our result is 1. 
Result so far: 40087.171
If we subtract 472 from 760, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 12:
If we divide 2880 by 472, we get 6 and a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 40087.1716
The remainder is 48 after subtracting 2832 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
480 divided by 472 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 40087.17161
If we subtract 472 from 480, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 472, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 40087.17161
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
The number 472 fits into 800 1 times, leaving a remainder of 328.
Record the quotient 1 as the next digit in the result. 
Result so far: 40087.1716101
Deduct 472 from 800 and we're left 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.

Going ahead to step 16:
If we divide 3280 by 472, we get 6 and a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 40087.17161016
If we take 2832 away from 3280, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 40087.17161016, with a leftover of 4.48e-07.
