We're dividing 67012171 by 993 
The aim is to understand the frequency of 993 in 67012171.

Advancing to step 1:
993 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 993

Step 2:
The number 993 fits into 67 0 times, leaving a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 993

Going ahead to step 3:
The number 993 fits into 670 0 times, leaving a remainder of 670.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 670 after subtracting 0 from 670.
Append the next digit (1) from the dividend to 670 and continue with: 6701 / 993

Let's proceed to step 4:
The number 993 fits into 6701 6 times, leaving a remainder of 743.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 5958 from 6701 to get 743.
Include the next digit (2) from the dividend after 743, then repeat: 7432 / 993

On to step 5:
The number 993 fits into 7432 7 times, leaving a remainder of 481.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Deduct 6951 from 7432 and we're left with 481.
Grab the next digit (1) from the dividend, add it to 481, then carry on: 4811 / 993

On to step 6:
993 goes into 4811 4 times with a remainder of 839.
Record the quotient 4 as the next digit in the result. 
Result so far: 674.0
If we take 3972 away from 4811, we end up with 839.
Bring next digit (7) of the dividend behind the 839 and repeat the process: 8397 / 993

On to step 7:
When dividing 8397 by 993, we get 8 with a remainder of 453.
Record the quotient 8 as the next digit in the result. 
Result so far: 6748.0
Subtracting 7944 from 8397 leaves us with 453.
Grab the next digit (1) from the dividend, add it to 453, then carry on: 4531 / 993

On to step 8:
993 can be fit into 4531 4 times, resulting in a remainder of 559.
Use 4 as the next digit of our solution. 
Result so far: 67484.0
Deduct 3972 from 4531 and we're left with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

On to step 9:
If we divide 5590 by 993, we get 5 and a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 67484.5
If we subtract 4965 from 5590, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 10:
When dividing 6250 by 993, we get 6 with a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 67484.56
Subtract 5958 from 6250 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 11:
If we divide 2920 by 993, we get 2 and a remainder of 934.
The number 2 becomes the next digit in our result. 
Result so far: 67484.562
The remainder is 934 after subtracting 1986 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Let's proceed to step 12:
If we divide 9340 by 993, we get 9 and a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 67484.5629
If we take 8937 away from 9340, we end up with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 13:
993 can be fit into 4030 4 times, resulting in a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 67484.56294
Subtracting 3972 from 4030 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
580 divided by 993 is 0 with a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 67484.56294
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 15:
993 goes into 5800 5 times with a remainder of 835.
Put 5 as the next digit of the answer. 
Result so far: 67484.5629405
If we take 4965 away from 5800, we end up with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Step 16:
8350 divided by 993 is 8 with a remainder of 406.
The number 8 becomes the next digit in our result. 
Result so far: 67484.56294058
Subtract 7944 from 8350 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Our division results in 67484.56294058 with a remaining 4.06e-07.
