84242989 ÷ 993 
The aim is to understand the frequency of 993 in 84242989.

On to step 1:
When dividing 8 by 993, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 993

Step 2:
993 goes into 84 0 times with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 993

Let's proceed to step 3:
The number 993 fits into 842 0 times, leaving a remainder of 842.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 842, we end up with 842.
Bring next digit (4) of the dividend behind the 842 and repeat the process: 8424 / 993

On to step 4:
If we divide 8424 by 993, we get 8 and a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 7944 from 8424 and we're left with 480.
Include the next digit (2) from the dividend after 480, then repeat: 4802 / 993

On to step 5:
993 goes into 4802 4 times with a remainder of 830.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 830 after subtracting 3972 from 4802.
Append the next digit (9) from the dividend to 830 and continue with: 8309 / 993

Advancing to step 6:
8309 divided by 993 is 8 with a remainder of 365.
The number 8 becomes the next digit in our result. 
Result so far: 848.0
If we subtract 7944 from 8309, we get 365.
Grab the next digit (8) from the dividend, add it to 365, then carry on: 3658 / 993

Going ahead to step 7:
When dividing 3658 by 993, we get 3 with a remainder of 679.
Write down 3 as next digit of the result. 
Result so far: 8483.0
Subtracting 2979 from 3658 leaves us with 679.
Append the next digit (9) from the dividend to 679 and continue with: 6799 / 993

Let's proceed to step 8:
6799 divided by 993 is 6 with a remainder of 841.
Record the quotient 6 as the next digit in the result. 
Result so far: 84836.0
Subtracting 5958 from 6799 leaves us with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Moving on to step 9:
993 goes into 8410 8 times with a remainder of 466.
Write down 8 as next digit of the result. 
Result so far: 84836.8
If we subtract 7944 from 8410, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 10:
993 can be fit into 4660 4 times, resulting in a remainder of 688.
Write down 4 as next digit of the result. 
Result so far: 84836.84
Subtract 3972 from 4660 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 11:
993 can be fit into 6880 6 times, resulting in a remainder of 922.
The number 6 becomes the next digit in our result. 
Result so far: 84836.846
If we take 5958 away from 6880, we end up with 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Advancing to step 12:
993 can be fit into 9220 9 times, resulting in a remainder of 283.
Record the quotient 9 as the next digit in the result. 
Result so far: 84836.8469
Subtracting 8937 from 9220 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 13:
The number 993 fits into 2830 2 times, leaving a remainder of 844.
Write down 2 as next digit of the result. 
Result so far: 84836.84692
If we take 1986 away from 2830, we end up with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

On to step 14:
The number 993 fits into 8440 8 times, leaving a remainder of 496.
The next digit of our result is 8. 
Result so far: 84836.846928
If we take 7944 away from 8440, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 15:
4960 divided by 993 is 4 with a remainder of 988.
Write down 4 as next digit of the result. 
Result so far: 84836.8469284
If we subtract 3972 from 4960, we get 988.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9880, and continue the process.

Let's proceed to step 16:
If we divide 9880 by 993, we get 9 and a remainder of 943.
The number 9 becomes the next digit in our result. 
Result so far: 84836.84692849
Subtracting 8937 from 9880 leaves us with 943.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

In conclusion, the division gives 84836.84692849 with a balance of 9.43e-07.
