We divide 986390 by 66
The aim is to understand the frequency of 66 in 986390.

Let's proceed to step 1:
66 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 66

Step 2:
66 goes into 98 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 66 from 98 leaves us with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 66

Moving on to step 3:
The number 66 fits into 326 4 times, leaving a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 264 from 326 to get 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 66

Let's proceed to step 4:
When dividing 623 by 66, we get 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 149.0
If we subtract 594 from 623, we get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 66

Going ahead to step 5:
When dividing 299 by 66, we get 4 with a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 1494.0
Deduct 264 from 299 and we're left with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 66

Moving on to step 6:
350 divided by 66 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 14945.0
The remainder is 20 after subtracting 330 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 66, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 14945.3
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
66 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 14945.3
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
66 goes into 200 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 14945.303
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
66 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 14945.303
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
66 goes into 200 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 14945.30303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
If we divide 20 by 66, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 14945.30303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
200 divided by 66 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 14945.3030303
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 14945.3030303
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 14945.3030303 with a remainder of 2e-08.
