We're dividing 76111251 by 451 
The aim is to understand the frequency of 451 in 76111251.

Going ahead to step 1:
7 divided by 451 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 451

Going ahead to step 2:
76 divided by 451 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Fetch the next digit (1) from the dividend, attach it to 76 and continue: 761 / 451

Let's proceed to step 3:
If we divide 761 by 451, we get 1 and a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 451 from 761 leaves us with 310.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 451

Advancing to step 4:
The number 451 fits into 3101 6 times, leaving a remainder of 395.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 2706 away from 3101, we end up with 395.
Bring next digit (1) of the dividend behind the 395 and repeat the process: 3951 / 451

Step 5:
451 goes into 3951 8 times with a remainder of 343.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
The remainder is 343 after subtracting 3608 from 3951.
Include the next digit (2) from the dividend after 343, then repeat: 3432 / 451

On to step 6:
451 goes into 3432 7 times with a remainder of 275.
Write down 7 as next digit of the result. 
Result so far: 1687.0
Subtracting 3157 from 3432 leaves us with 275.
Include the next digit (5) from the dividend after 275, then repeat: 2755 / 451

On to step 7:
When dividing 2755 by 451, we get 6 with a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 16876.0
The remainder is 49 after subtracting 2706 from 2755.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 451

Going ahead to step 8:
451 goes into 491 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 168761.0
If we subtract 451 from 491, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 451 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 168761.0
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 10:
451 goes into 4000 8 times with a remainder of 392.
The next digit of our result is 8. 
Result so far: 168761.08
Subtract 3608 from 4000 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 11:
When dividing 3920 by 451, we get 8 with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 168761.088
If we take 3608 away from 3920, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 168761.088 with a remainder of 0.0312.
