We look at the division of 958593 by 66 
The aim is to understand the frequency of 66 in 958593.

Moving on to step 1:
The number 66 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 66

Going ahead to step 2:
66 goes into 95 1 times with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 66 from 95 to get 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 66

Moving on to step 3:
66 goes into 298 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 34 after subtracting 264 from 298.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 66

Moving on to step 4:
When dividing 345 by 66, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 145.0
Subtracting 330 from 345 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 66

Step 5:
If we divide 159 by 66, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 1452.0
Subtract 132 from 159 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 66

Step 6:
66 can be fit into 273 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 14524.0
If we subtract 264 from 273, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
66 can be fit into 90 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 14524.1
If we subtract 66 from 90, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 66, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 14524.13
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 14524.136
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 14524.1363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
When dividing 420 by 66, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 14524.13636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 14524.136363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 14524.1363636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
240 divided by 66 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 14524.13636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 14524.13636363 with a remaining 4.2e-08.
