We look at the division of 38605877 by 451 
The aim is to understand the frequency of 451 in 38605877.

Advancing to step 1:
451 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 451

Step 2:
If we divide 38 by 451, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 451

Moving on to step 3:
386 divided by 451 is 0 with a remainder of 386.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 386 leaves us with 386.
Fetch the next digit (0) from the dividend, attach it to 386 and continue: 3860 / 451

Let's proceed to step 4:
When dividing 3860 by 451, we get 8 with a remainder of 252.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 3608 from 3860 leaves us with 252.
Bring next digit (5) of the dividend behind the 252 and repeat the process: 2525 / 451

On to step 5:
If we divide 2525 by 451, we get 5 and a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 2255 from 2525 and we're left with 270.
Append the next digit (8) from the dividend to 270 and continue with: 2708 / 451

Advancing to step 6:
If we divide 2708 by 451, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 856.0
If we subtract 2706 from 2708, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 451

On to step 7:
451 goes into 27 0 times with a remainder of 27.
The next digit of our result is 0. 
Result so far: 8560.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (7) from the dividend, attach it to 27 and continue: 277 / 451

Going ahead to step 8:
If we divide 277 by 451, we get 0 and a remainder of 277.
Put 0 as the next digit of the answer. 
Result so far: 85600.0
Deduct 0 from 277 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 9:
The number 451 fits into 2770 6 times, leaving a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 85600.6
Deduct 2706 from 2770 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
451 goes into 640 1 times with a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 85600.61
If we subtract 451 from 640, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 11:
If we divide 1890 by 451, we get 4 and a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 85600.614
The remainder is 86 after subtracting 1804 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 12:
451 can be fit into 860 1 times, resulting in a remainder of 409.
The number 1 becomes the next digit in our result. 
Result so far: 85600.6141
Subtract 451 from 860 to get 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 13:
If we divide 4090 by 451, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 85600.61419
Subtracting 4059 from 4090 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.

Going ahead to step 14:
If we divide 310 by 451, we get 0 and a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 85600.61419
Subtracting 0 from 310 leaves us 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.

Advancing to step 15:
The number 451 fits into 3100 6 times, leaving a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 85600.6141906
The remainder is 394 after subtracting 2706 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 16:
The number 451 fits into 3940 8 times, leaving a remainder of 332.
Use 8 as the next digit of our solution. 
Result so far: 85600.61419068
If we subtract 3608 from 3940, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The quotient of the division is 85600.61419068, and the remainder is 3.32e-07.
