Let's divide 915470 by 66
The aim is to understand the frequency of 66 in 915470.

Let's proceed to step 1:
If we divide 9 by 66, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 66

Advancing to step 2:
66 can be fit into 91 1 times, resulting in a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 91 to get 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 66

Going ahead to step 3:
66 can be fit into 255 3 times, resulting in a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 198 from 255 and we're left with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 66

Step 4:
66 can be fit into 574 8 times, resulting in a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we take 528 away from 574, we end up with 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 66

Step 5:
66 goes into 467 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 1387.0
Deduct 462 from 467 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 66

Step 6:
66 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 13870.0
If we take 0 away from 50, we end up 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.

Going ahead to step 7:
500 divided by 66 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 13870.7
If we subtract 462 from 500, 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.
The number 5 becomes the next digit in our result. 
Result so far: 13870.75
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.

On to step 9:
66 goes into 500 7 times with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 13870.757
Subtract 462 from 500 to 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 10:
66 goes into 380 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 13870.7575
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.

Moving on to step 11:
66 can be fit into 500 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 13870.75757
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 12:
66 goes into 380 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 13870.757575
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.

Let's proceed to step 13:
66 goes into 500 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 13870.7575757
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.

Going ahead to step 14:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 13870.75757575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 13870.75757575 and a remainder of 5e-08.
