Let's divide 66327856 by 993
The aim is to understand the frequency of 993 in 66327856.

Going ahead to step 1:
6 divided by 993 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 993

Moving on to step 2:
When dividing 66 by 993, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 993

Moving on to step 3:
663 divided by 993 is 0 with a remainder of 663.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 663, we get 663.
Include the next digit (2) from the dividend after 663, then repeat: 6632 / 993

Advancing to step 4:
6632 divided by 993 is 6 with a remainder of 674.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5958 away from 6632, we end up with 674.
Grab the next digit (7) from the dividend, add it to 674, then carry on: 6747 / 993

Advancing to step 5:
The number 993 fits into 6747 6 times, leaving a remainder of 789.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 789 after subtracting 5958 from 6747.
Take the next digit (8) from the dividend and append it to 789, then repeat: 7898 / 993

Advancing to step 6:
993 goes into 7898 7 times with a remainder of 947.
Use 7 as the next digit of our solution. 
Result so far: 667.0
If we take 6951 away from 7898, we end up with 947.
Grab the next digit (5) from the dividend, add it to 947, then carry on: 9475 / 993

Advancing to step 7:
993 goes into 9475 9 times with a remainder of 538.
Put 9 as the next digit of the answer. 
Result so far: 6679.0
The remainder is 538 after subtracting 8937 from 9475.
Fetch the next digit (6) from the dividend, attach it to 538 and continue: 5386 / 993

Advancing to step 8:
When dividing 5386 by 993, we get 5 with a remainder of 421.
Use 5 as the next digit of our solution. 
Result so far: 66795.0
If we subtract 4965 from 5386, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Advancing to step 9:
993 can be fit into 4210 4 times, resulting in a remainder of 238.
Write down 4 as next digit of the result. 
Result so far: 66795.4
Subtract 3972 from 4210 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 10:
If we divide 2380 by 993, we get 2 and a remainder of 394.
The number 2 becomes the next digit in our result. 
Result so far: 66795.42
Subtract 1986 from 2380 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Moving on to step 11:
993 can be fit into 3940 3 times, resulting in a remainder of 961.
Record the quotient 3 as the next digit in the result. 
Result so far: 66795.423
If we take 2979 away from 3940, we end up with 961.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9610, and continue the process.

Moving on to step 12:
When dividing 9610 by 993, we get 9 with a remainder of 673.
Use 9 as the next digit of our solution. 
Result so far: 66795.4239
If we subtract 8937 from 9610, we get 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Going ahead to step 13:
The number 993 fits into 6730 6 times, leaving a remainder of 772.
The number 6 becomes the next digit in our result. 
Result so far: 66795.42396
Subtract 5958 from 6730 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 14:
993 can be fit into 7720 7 times, resulting in a remainder of 769.
The next digit of our result is 7. 
Result so far: 66795.423967
If we subtract 6951 from 7720, we get 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Going ahead to step 15:
If we divide 7690 by 993, we get 7 and a remainder of 739.
Use 7 as the next digit of our solution. 
Result so far: 66795.4239677
If we take 6951 away from 7690, we end up with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

The final result is 66795.4239677 with a remainder of 7.39e-06.
