We look at the division of 79858721 by 924 
The aim is to understand the frequency of 924 in 79858721.

Let's proceed to step 1:
924 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 924

On to step 2:
The number 924 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 924

Moving on to step 3:
When dividing 798 by 924, we get 0 with a remainder of 798.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 798 after subtracting 0 from 798.
Bring next digit (5) of the dividend behind the 798 and repeat the process: 7985 / 924

Let's proceed to step 4:
7985 divided by 924 is 8 with a remainder of 593.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7392 from 7985, we get 593.
Fetch the next digit (8) from the dividend, attach it to 593 and continue: 5938 / 924

Let's proceed to step 5:
5938 divided by 924 is 6 with a remainder of 394.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Deduct 5544 from 5938 and we're left with 394.
Fetch the next digit (7) from the dividend, attach it to 394 and continue: 3947 / 924

Moving on to step 6:
If we divide 3947 by 924, we get 4 and a remainder of 251.
The number 4 becomes the next digit in our result. 
Result so far: 864.0
If we take 3696 away from 3947, we end up with 251.
Take the next digit (2) from the dividend and append it to 251, then repeat: 2512 / 924

Step 7:
924 can be fit into 2512 2 times, resulting in a remainder of 664.
The number 2 becomes the next digit in our result. 
Result so far: 8642.0
Subtract 1848 from 2512 to get 664.
Bring next digit (1) of the dividend behind the 664 and repeat the process: 6641 / 924

Step 8:
The number 924 fits into 6641 7 times, leaving a remainder of 173.
Record the quotient 7 as the next digit in the result. 
Result so far: 86427.0
If we subtract 6468 from 6641, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 9:
When dividing 1730 by 924, we get 1 with a remainder of 806.
The number 1 becomes the next digit in our result. 
Result so far: 86427.1
Deduct 924 from 1730 and we're left with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Advancing to step 10:
924 goes into 8060 8 times with a remainder of 668.
Write down 8 as next digit of the result. 
Result so far: 86427.18
Deduct 7392 from 8060 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Moving on to step 11:
6680 divided by 924 is 7 with a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 86427.187
Subtract 6468 from 6680 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 12:
924 can be fit into 2120 2 times, resulting in a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 86427.1872
If we take 1848 away from 2120, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 13:
2720 divided by 924 is 2 with a remainder of 872.
Record the quotient 2 as the next digit in the result. 
Result so far: 86427.18722
If we subtract 1848 from 2720, we get 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

The quotient of the division is 86427.18722, and the remainder is 0.000872.
