Let's divide 17646961 by 993
The aim is to understand the frequency of 993 in 17646961.

Going ahead to step 1:
1 divided by 993 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 993

Let's proceed to step 2:
The number 993 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 993

On to step 3:
The number 993 fits into 176 0 times, leaving a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 176, we get 176.
Include the next digit (4) from the dividend after 176, then repeat: 1764 / 993

Moving on to step 4:
The number 993 fits into 1764 1 times, leaving a remainder of 771.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 993 from 1764 to get 771.
Take the next digit (6) from the dividend and append it to 771, then repeat: 7716 / 993

Going ahead to step 5:
993 goes into 7716 7 times with a remainder of 765.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 6951 away from 7716, we end up with 765.
Fetch the next digit (9) from the dividend, attach it to 765 and continue: 7659 / 993

Advancing to step 6:
If we divide 7659 by 993, we get 7 and a remainder of 708.
Put 7 as the next digit of the answer. 
Result so far: 177.0
If we take 6951 away from 7659, we end up with 708.
Bring next digit (6) of the dividend behind the 708 and repeat the process: 7086 / 993

On to step 7:
If we divide 7086 by 993, we get 7 and a remainder of 135.
The number 7 becomes the next digit in our result. 
Result so far: 1777.0
Subtracting 6951 from 7086 leaves us with 135.
Take the next digit (1) from the dividend and append it to 135, then repeat: 1351 / 993

Going ahead to step 8:
The number 993 fits into 1351 1 times, leaving a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 17771.0
Subtract 993 from 1351 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 9:
When dividing 3580 by 993, we get 3 with a remainder of 601.
The number 3 becomes the next digit in our result. 
Result so far: 17771.3
Subtract 2979 from 3580 to 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.

Let's proceed to step 10:
If we divide 6010 by 993, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 17771.36
Subtracting 5958 from 6010 leaves us 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.

Going ahead to step 11:
The number 993 fits into 520 0 times, leaving a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 17771.36
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
When dividing 5200 by 993, we get 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 17771.3605
If we subtract 4965 from 5200, we 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.

Step 13:
When dividing 2350 by 993, we get 2 with a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 17771.36052
If we take 1986 away from 2350, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 14:
The number 993 fits into 3640 3 times, leaving a remainder of 661.
Record the quotient 3 as the next digit in the result. 
Result so far: 17771.360523
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.

Going ahead to step 15:
6610 divided by 993 is 6 with a remainder of 652.
Put 6 as the next digit of the answer. 
Result so far: 17771.3605236
Deduct 5958 from 6610 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 16:
The number 993 fits into 6520 6 times, leaving a remainder of 562.
Use 6 as the next digit of our solution. 
Result so far: 17771.36052366
The remainder is 562 after subtracting 5958 from 6520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Our division results in 17771.36052366 with a remaining 5.62e-07.
