We look at the division of 71176750 by 450 
The aim is to understand the frequency of 450 in 71176750.

Moving on to step 1:
If we divide 7 by 450, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 450

On to step 2:
When dividing 71 by 450, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (1) from the dividend and append it to 71, then repeat: 711 / 450

On to step 3:
450 can be fit into 711 1 times, resulting in a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 450 from 711 and we're left with 261.
Append the next digit (7) from the dividend to 261 and continue with: 2617 / 450

Moving on to step 4:
If we divide 2617 by 450, we get 5 and a remainder of 367.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2250 from 2617, we get 367.
Append the next digit (6) from the dividend to 367 and continue with: 3676 / 450

On to step 5:
If we divide 3676 by 450, we get 8 and a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 158.0
If we take 3600 away from 3676, we end up with 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 450

Step 6:
The number 450 fits into 767 1 times, leaving a remainder of 317.
Record the quotient 1 as the next digit in the result. 
Result so far: 1581.0
Subtract 450 from 767 to get 317.
Append the next digit (5) from the dividend to 317 and continue with: 3175 / 450

On to step 7:
The number 450 fits into 3175 7 times, leaving a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 15817.0
Subtract 3150 from 3175 to get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 450

Let's proceed to step 8:
250 divided by 450 is 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 158170.0
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 9:
When dividing 2500 by 450, we get 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 158170.5
If we subtract 2250 from 2500, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
450 goes into 2500 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 158170.55
Subtract 2250 from 2500 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The quotient of the division is 158170.55, and the remainder is 0.25.
