Let's divide 875103 by 66
The aim is to understand the frequency of 66 in 875103.

On to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 66

Advancing to step 2:
The number 66 fits into 87 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 66 from 87 leaves us with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 66

On to step 3:
When dividing 215 by 66, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 17 after subtracting 198 from 215.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 66

Step 4:
66 can be fit into 171 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we subtract 132 from 171, we get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 66

On to step 5:
When dividing 390 by 66, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1325.0
Deduct 330 from 390 and we're left with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 66

Advancing to step 6:
The number 66 fits into 603 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 13259.0
If we take 594 away from 603, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 66 is 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 13259.1
If we subtract 66 from 90, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 13259.13
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
420 divided by 66 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 13259.136
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
66 goes into 240 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 13259.1363
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
66 goes into 420 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 13259.13636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
240 divided by 66 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 13259.136363
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
If we divide 420 by 66, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 13259.1363636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 13259.13636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 13259.13636363, with a leftover of 4.2e-08.
