We're dividing 843019 by 66 
The aim is to understand the frequency of 66 in 843019.

Moving on to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 66

On to step 2:
The number 66 fits into 84 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 66 from 84 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 66

Moving on to step 3:
183 divided by 66 is 2 with a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 51 after subtracting 132 from 183.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 66

On to step 4:
When dividing 510 by 66, we get 7 with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtract 462 from 510 to get 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 66

Let's proceed to step 5:
66 can be fit into 481 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 1277.0
Subtracting 462 from 481 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 66

Going ahead to step 6:
If we divide 199 by 66, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 12773.0
If we subtract 198 from 199, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 66 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12773.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 66 fits into 100 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 12773.01
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
66 goes into 340 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12773.015
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 12773.0151
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
66 can be fit into 340 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12773.01515
Subtract 330 from 340 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 12773.015151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
340 divided by 66 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 12773.0151515
Subtracting 330 from 340 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 66, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 12773.01515151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 12773.01515151, and the remainder is 3.4e-08.
