We divide 100370 by 66
The aim is to understand the frequency of 66 in 100370.

Advancing to step 1:
If we divide 1 by 66, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 66

Moving on to step 2:
10 divided by 66 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 66

Going ahead to step 3:
66 goes into 100 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 66 from 100 leaves us with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 66

Advancing to step 4:
If we divide 343 by 66, we get 5 and a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 330 from 343 to get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 66

Step 5:
When dividing 137 by 66, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we subtract 132 from 137, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 66

Going ahead to step 6:
66 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 1520.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
If we divide 500 by 66, we get 7 and a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 1520.7
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.

Moving on to step 8:
If we divide 380 by 66, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1520.75
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.

Going ahead to step 9:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1520.757
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 10:
If we divide 380 by 66, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 1520.7575
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.

Advancing to step 11:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1520.75757
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.

Step 12:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1520.757575
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 13:
When dividing 500 by 66, we get 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1520.7575757
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:
66 goes into 380 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1520.75757575
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.

After the division, we end up with 1520.75757575 and a remainder of 5e-08.
