99124143 divided by 994 
The aim is to understand the frequency of 994 in 99124143.

Moving on to step 1:
If we divide 9 by 994, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 994

Going ahead to step 2:
994 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 994

Advancing to step 3:
The number 994 fits into 991 0 times, leaving a remainder of 991.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 991 to get 991.
Include the next digit (2) from the dividend after 991, then repeat: 9912 / 994

Step 4:
When dividing 9912 by 994, we get 9 with a remainder of 966.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 8946 from 9912 to get 966.
Append the next digit (4) from the dividend to 966 and continue with: 9664 / 994

Moving on to step 5:
The number 994 fits into 9664 9 times, leaving a remainder of 718.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Subtract 8946 from 9664 to get 718.
Include the next digit (1) from the dividend after 718, then repeat: 7181 / 994

Step 6:
The number 994 fits into 7181 7 times, leaving a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 997.0
Subtract 6958 from 7181 to get 223.
Grab the next digit (4) from the dividend, add it to 223, then carry on: 2234 / 994

Let's proceed to step 7:
When dividing 2234 by 994, we get 2 with a remainder of 246.
The next digit of our result is 2. 
Result so far: 9972.0
The remainder is 246 after subtracting 1988 from 2234.
Fetch the next digit (3) from the dividend, attach it to 246 and continue: 2463 / 994

Let's proceed to step 8:
994 goes into 2463 2 times with a remainder of 475.
Put 2 as the next digit of the answer. 
Result so far: 99722.0
The remainder is 475 after subtracting 1988 from 2463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Let's proceed to step 9:
994 can be fit into 4750 4 times, resulting in a remainder of 774.
The next digit of our result is 4. 
Result so far: 99722.4
If we subtract 3976 from 4750, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Going ahead to step 10:
When dividing 7740 by 994, we get 7 with a remainder of 782.
Use 7 as the next digit of our solution. 
Result so far: 99722.47
Subtracting 6958 from 7740 leaves us with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Moving on to step 11:
The number 994 fits into 7820 7 times, leaving a remainder of 862.
Write down 7 as next digit of the result. 
Result so far: 99722.477
If we take 6958 away from 7820, we end up with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

The final result is 99722.477 with a remainder of 0.0862.
