Let's divide 97810981 by 450
The aim is to understand the frequency of 450 in 97810981.

Advancing to step 1:
If we divide 9 by 450, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 450

Let's proceed to step 2:
97 divided by 450 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 450

Going ahead to step 3:
978 divided by 450 is 2 with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 900 from 978 leaves us with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 450

Step 4:
450 can be fit into 781 1 times, resulting in a remainder of 331.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 450 from 781 leaves us with 331.
Grab the next digit (0) from the dividend, add it to 331, then carry on: 3310 / 450

On to step 5:
If we divide 3310 by 450, we get 7 and a remainder of 160.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
The remainder is 160 after subtracting 3150 from 3310.
Take the next digit (9) from the dividend and append it to 160, then repeat: 1609 / 450

Going ahead to step 6:
450 goes into 1609 3 times with a remainder of 259.
Write down 3 as next digit of the result. 
Result so far: 2173.0
The remainder is 259 after subtracting 1350 from 1609.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 450

On to step 7:
450 can be fit into 2598 5 times, resulting in a remainder of 348.
Record the quotient 5 as the next digit in the result. 
Result so far: 21735.0
Deduct 2250 from 2598 and we're left with 348.
Fetch the next digit (1) from the dividend, attach it to 348 and continue: 3481 / 450

Step 8:
3481 divided by 450 is 7 with a remainder of 331.
The number 7 becomes the next digit in our result. 
Result so far: 217357.0
Subtracting 3150 from 3481 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 9:
3310 divided by 450 is 7 with a remainder of 160.
Use 7 as the next digit of our solution. 
Result so far: 217357.7
The remainder is 160 after subtracting 3150 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
1600 divided by 450 is 3 with a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 217357.73
Subtract 1350 from 1600 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.

Going ahead to step 11:
2500 divided by 450 is 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 217357.735
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.

Going ahead to step 12:
When dividing 2500 by 450, we get 5 with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 217357.7355
The remainder is 250 after subtracting 2250 from 2500.
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 217357.7355, and the remainder is 0.0025.
