Let's divide 90972807 by 500
The aim is to understand the frequency of 500 in 90972807.

Going ahead to step 1:
When dividing 9 by 500, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 500

Advancing to step 2:
When dividing 90 by 500, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 500

Advancing to step 3:
When dividing 909 by 500, we get 1 with a remainder of 409.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 500 from 909 and we're left with 409.
Bring next digit (7) of the dividend behind the 409 and repeat the process: 4097 / 500

On to step 4:
If we divide 4097 by 500, we get 8 and a remainder of 97.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 97 after subtracting 4000 from 4097.
Append the next digit (2) from the dividend to 97 and continue with: 972 / 500

On to step 5:
If we divide 972 by 500, we get 1 and a remainder of 472.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
If we subtract 500 from 972, we get 472.
Fetch the next digit (8) from the dividend, attach it to 472 and continue: 4728 / 500

Moving on to step 6:
4728 divided by 500 is 9 with a remainder of 228.
The number 9 becomes the next digit in our result. 
Result so far: 1819.0
Subtracting 4500 from 4728 leaves us with 228.
Bring next digit (0) of the dividend behind the 228 and repeat the process: 2280 / 500

Let's proceed to step 7:
2280 divided by 500 is 4 with a remainder of 280.
Record the quotient 4 as the next digit in the result. 
Result so far: 18194.0
Deduct 2000 from 2280 and we're left with 280.
Take the next digit (7) from the dividend and append it to 280, then repeat: 2807 / 500

Let's proceed to step 8:
2807 divided by 500 is 5 with a remainder of 307.
Use 5 as the next digit of our solution. 
Result so far: 181945.0
Subtracting 2500 from 2807 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Advancing to step 9:
3070 divided by 500 is 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 181945.6
The remainder is 70 after subtracting 3000 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 500 is 1 with a remainder of 200.
Record the quotient 1 as the next digit in the result. 
Result so far: 181945.61
If we subtract 500 from 700, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 11:
500 goes into 2000 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 181945.614
Subtracting 2000 from 2000 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
When dividing 0 by 500, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 181945.614
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
If we divide 0 by 500, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 181945.614
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 181945.614, with a leftover of 0.0.
