Let's divide 587495 by 66
The aim is to understand the frequency of 66 in 587495.

Step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 66

Step 2:
If we divide 58 by 66, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 66

Advancing to step 3:
When dividing 587 by 66, we get 8 with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 528 from 587, we get 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 66

Step 4:
The number 66 fits into 594 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 594 from 594 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 66

Moving on to step 5:
66 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 66

On to step 6:
If we divide 95 by 66, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 8901.0
If we take 66 away from 95, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
66 goes into 290 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 8901.4
If we subtract 264 from 290, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
66 goes into 260 3 times with a remainder of 62.
The next digit of our result is 3. 
Result so far: 8901.43
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
The number 66 fits into 620 9 times, leaving a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 8901.439
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 66, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 8901.4393
Subtract 198 from 260 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
When dividing 620 by 66, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 8901.43939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
If we divide 260 by 66, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 8901.439393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 13:
When dividing 620 by 66, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 8901.4393939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
If we divide 260 by 66, we get 3 and a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 8901.43939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 8901.43939393, with a leftover of 6.2e-08.
