Let's divide 958788 by 66
The aim is to understand the frequency of 66 in 958788.

Let's proceed to step 1:
9 divided by 66 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 66

Let's proceed to step 2:
When dividing 95 by 66, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 66 away from 95, we end up with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 66

Moving on to step 3:
If we divide 298 by 66, we get 4 and a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 264 from 298 and we're left with 34.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 66

Step 4:
66 goes into 347 5 times with a remainder of 17.
The next digit of our result is 5. 
Result so far: 145.0
If we take 330 away from 347, we end up with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 66

Going ahead to step 5:
178 divided by 66 is 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 1452.0
The remainder is 46 after subtracting 132 from 178.
Grab the next digit (8) from the dividend, add it to 46, then carry on: 468 / 66

On to step 6:
468 divided by 66 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 14527.0
If we subtract 462 from 468, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 66, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 14527.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 14527.09
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 66, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 14527.09
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 66, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 14527.0909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
60 divided by 66 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 14527.0909
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 66, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 14527.090909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
66 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 14527.090909
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
The number 66 fits into 600 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 14527.09090909
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 14527.09090909, with a leftover of 6e-09.
