We look at the division of 9054535 by 451 
The aim is to understand the frequency of 451 in 9054535.

Going ahead to step 1:
451 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 451

On to step 2:
When dividing 90 by 451, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 451

Moving on to step 3:
If we divide 905 by 451, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 902 from 905 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 451

Moving on to step 4:
34 divided by 451 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 451

Moving on to step 5:
451 can be fit into 345 0 times, resulting in a remainder of 345.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we subtract 0 from 345, we get 345.
Grab the next digit (3) from the dividend, add it to 345, then carry on: 3453 / 451

Let's proceed to step 6:
When dividing 3453 by 451, we get 7 with a remainder of 296.
Write down 7 as next digit of the result. 
Result so far: 2007.0
Subtracting 3157 from 3453 leaves us with 296.
Grab the next digit (5) from the dividend, add it to 296, then carry on: 2965 / 451

Moving on to step 7:
451 can be fit into 2965 6 times, resulting in a remainder of 259.
Use 6 as the next digit of our solution. 
Result so far: 20076.0
Subtract 2706 from 2965 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 8:
If we divide 2590 by 451, we get 5 and a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 20076.5
The remainder is 335 after subtracting 2255 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 9:
3350 divided by 451 is 7 with a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 20076.57
If we subtract 3157 from 3350, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 10:
When dividing 1930 by 451, we get 4 with a remainder of 126.
The next digit of our result is 4. 
Result so far: 20076.574
The remainder is 126 after subtracting 1804 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 11:
When dividing 1260 by 451, we get 2 with a remainder of 358.
The number 2 becomes the next digit in our result. 
Result so far: 20076.5742
Subtracting 902 from 1260 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 12:
451 can be fit into 3580 7 times, resulting in a remainder of 423.
Put 7 as the next digit of the answer. 
Result so far: 20076.57427
The remainder is 423 after subtracting 3157 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 13:
The number 451 fits into 4230 9 times, leaving a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 20076.574279
Deduct 4059 from 4230 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 14:
451 goes into 1710 3 times with a remainder of 357.
Put 3 as the next digit of the answer. 
Result so far: 20076.5742793
The remainder is 357 after subtracting 1353 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 15:
451 can be fit into 3570 7 times, resulting in a remainder of 413.
Write down 7 as next digit of the result. 
Result so far: 20076.57427937
The remainder is 413 after subtracting 3157 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Our division results in 20076.57427937 with a remaining 4.13e-07.
