73228729 ÷ 993 
The aim is to understand the frequency of 993 in 73228729.

Let's proceed to step 1:
The number 993 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 993

Moving on to step 2:
When dividing 73 by 993, we get 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 993

Going ahead to step 3:
If we divide 732 by 993, we get 0 and a remainder of 732.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 732 and we're left with 732.
Grab the next digit (2) from the dividend, add it to 732, then carry on: 7322 / 993

Advancing to step 4:
The number 993 fits into 7322 7 times, leaving a remainder of 371.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 6951 from 7322 and we're left with 371.
Append the next digit (8) from the dividend to 371 and continue with: 3718 / 993

Moving on to step 5:
993 can be fit into 3718 3 times, resulting in a remainder of 739.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we take 2979 away from 3718, we end up with 739.
Include the next digit (7) from the dividend after 739, then repeat: 7397 / 993

On to step 6:
993 can be fit into 7397 7 times, resulting in a remainder of 446.
Write down 7 as next digit of the result. 
Result so far: 737.0
Subtracting 6951 from 7397 leaves us with 446.
Append the next digit (2) from the dividend to 446 and continue with: 4462 / 993

Moving on to step 7:
If we divide 4462 by 993, we get 4 and a remainder of 490.
The next digit of our result is 4. 
Result so far: 7374.0
Deduct 3972 from 4462 and we're left with 490.
Fetch the next digit (9) from the dividend, attach it to 490 and continue: 4909 / 993

Advancing to step 8:
993 goes into 4909 4 times with a remainder of 937.
Put 4 as the next digit of the answer. 
Result so far: 73744.0
Subtract 3972 from 4909 to get 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

Step 9:
The number 993 fits into 9370 9 times, leaving a remainder of 433.
Write down 9 as next digit of the result. 
Result so far: 73744.9
If we take 8937 away from 9370, we end up with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Advancing to step 10:
When dividing 4330 by 993, we get 4 with a remainder of 358.
The number 4 becomes the next digit in our result. 
Result so far: 73744.94
Subtracting 3972 from 4330 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 11:
993 goes into 3580 3 times with a remainder of 601.
The next digit of our result is 3. 
Result so far: 73744.943
If we subtract 2979 from 3580, we get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 12:
When dividing 6010 by 993, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 73744.9436
If we take 5958 away from 6010, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
The number 993 fits into 520 0 times, leaving a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 73744.9436
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 14:
If we divide 5200 by 993, we get 5 and a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 73744.943605
Subtract 4965 from 5200 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 15:
993 can be fit into 2350 2 times, resulting in a remainder of 364.
The number 2 becomes the next digit in our result. 
Result so far: 73744.9436052
If we subtract 1986 from 2350, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 16:
3640 divided by 993 is 3 with a remainder of 661.
Write down 3 as next digit of the result. 
Result so far: 73744.94360523
If we subtract 2979 from 3640, we get 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6610, and continue the process.

Our division results in 73744.94360523 with a remaining 6.61e-07.
