We divide 857951 by 66
The aim is to understand the frequency of 66 in 857951.

Going ahead to step 1:
66 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 66

Let's proceed to step 2:
If we divide 85 by 66, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 66 from 85, we get 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 66

Step 3:
The number 66 fits into 197 2 times, leaving a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 65 after subtracting 132 from 197.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 66

On to step 4:
When dividing 659 by 66, we get 9 with a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 65 after subtracting 594 from 659.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 66

On to step 5:
655 divided by 66 is 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 1299.0
Deduct 594 from 655 and we're left with 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 66

Advancing to step 6:
When dividing 611 by 66, we get 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 12999.0
Subtracting 594 from 611 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 66, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 12999.2
If we subtract 132 from 170, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 12999.25
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
If we divide 500 by 66, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 12999.257
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12999.2575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
66 goes into 500 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 12999.25757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
If we divide 380 by 66, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12999.257575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
66 can be fit into 500 7 times, resulting in a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 12999.2575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
380 divided by 66 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12999.25757575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 12999.25757575 with a balance of 5e-08.
