We look at the division of 77494218 by 994 
The aim is to understand the frequency of 994 in 77494218.

Moving on to step 1:
994 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 994

Let's proceed to step 2:
When dividing 77 by 994, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 994

Let's proceed to step 3:
994 goes into 774 0 times with a remainder of 774.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 774 after subtracting 0 from 774.
Take the next digit (9) from the dividend and append it to 774, then repeat: 7749 / 994

Going ahead to step 4:
If we divide 7749 by 994, we get 7 and a remainder of 791.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6958 from 7749 leaves us with 791.
Append the next digit (4) from the dividend to 791 and continue with: 7914 / 994

Let's proceed to step 5:
If we divide 7914 by 994, we get 7 and a remainder of 956.
Use 7 as the next digit of our solution. 
Result so far: 77.0
Subtracting 6958 from 7914 leaves us with 956.
Bring next digit (2) of the dividend behind the 956 and repeat the process: 9562 / 994

Let's proceed to step 6:
When dividing 9562 by 994, we get 9 with a remainder of 616.
Use 9 as the next digit of our solution. 
Result so far: 779.0
The remainder is 616 after subtracting 8946 from 9562.
Take the next digit (1) from the dividend and append it to 616, then repeat: 6161 / 994

Step 7:
6161 divided by 994 is 6 with a remainder of 197.
Put 6 as the next digit of the answer. 
Result so far: 7796.0
If we take 5964 away from 6161, we end up with 197.
Bring next digit (8) of the dividend behind the 197 and repeat the process: 1978 / 994

Moving on to step 8:
994 can be fit into 1978 1 times, resulting in a remainder of 984.
Record the quotient 1 as the next digit in the result. 
Result so far: 77961.0
Subtract 994 from 1978 to get 984.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9840, and continue the process.

On to step 9:
9840 divided by 994 is 9 with a remainder of 894.
The next digit of our result is 9. 
Result so far: 77961.9
If we take 8946 away from 9840, we end up with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

On to step 10:
The number 994 fits into 8940 8 times, leaving a remainder of 988.
Use 8 as the next digit of our solution. 
Result so far: 77961.98
Deduct 7952 from 8940 and we're left with 988.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9880, and continue the process.

Advancing to step 11:
When dividing 9880 by 994, we get 9 with a remainder of 934.
Use 9 as the next digit of our solution. 
Result so far: 77961.989
The remainder is 934 after subtracting 8946 from 9880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

On to step 12:
If we divide 9340 by 994, we get 9 and a remainder of 394.
The next digit of our result is 9. 
Result so far: 77961.9899
The remainder is 394 after subtracting 8946 from 9340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

The final outcome is 77961.9899, with a leftover of 0.00394.
