46100098 ÷ 999 
The aim is to understand the frequency of 999 in 46100098.

Step 1:
999 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 999

Step 2:
When dividing 46 by 999, we get 0 with a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 46 leaves us with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 999

Let's proceed to step 3:
When dividing 461 by 999, we get 0 with a remainder of 461.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 461 after subtracting 0 from 461.
Include the next digit (0) from the dividend after 461, then repeat: 4610 / 999

Going ahead to step 4:
999 can be fit into 4610 4 times, resulting in a remainder of 614.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 614 after subtracting 3996 from 4610.
Include the next digit (0) from the dividend after 614, then repeat: 6140 / 999

Moving on to step 5:
999 can be fit into 6140 6 times, resulting in a remainder of 146.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 5994 from 6140 leaves us with 146.
Bring next digit (0) of the dividend behind the 146 and repeat the process: 1460 / 999

On to step 6:
999 can be fit into 1460 1 times, resulting in a remainder of 461.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
Subtract 999 from 1460 to get 461.
Grab the next digit (9) from the dividend, add it to 461, then carry on: 4619 / 999

On to step 7:
4619 divided by 999 is 4 with a remainder of 623.
The next digit of our result is 4. 
Result so far: 4614.0
If we subtract 3996 from 4619, we get 623.
Bring next digit (8) of the dividend behind the 623 and repeat the process: 6238 / 999

Step 8:
If we divide 6238 by 999, we get 6 and a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 46146.0
The remainder is 244 after subtracting 5994 from 6238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 9:
When dividing 2440 by 999, we get 2 with a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 46146.2
If we subtract 1998 from 2440, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Let's proceed to step 10:
4420 divided by 999 is 4 with a remainder of 424.
Use 4 as the next digit of our solution. 
Result so far: 46146.24
Subtract 3996 from 4420 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 11:
If we divide 4240 by 999, we get 4 and a remainder of 244.
Record the quotient 4 as the next digit in the result. 
Result so far: 46146.244
Deduct 3996 from 4240 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Our division results in 46146.244 with a remaining 0.0244.
