We divide 38015261 by 66
The aim is to understand the frequency of 66 in 38015261.

Advancing to step 1:
3 divided by 66 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 66

Step 2:
38 divided by 66 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 66

Going ahead to step 3:
66 goes into 380 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 330 from 380 leaves us with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 66

Advancing to step 4:
501 divided by 66 is 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 57.0
If we take 462 away from 501, we end up with 39.
Append the next digit (5) from the dividend to 39 and continue with: 395 / 66

Let's proceed to step 5:
66 goes into 395 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 575.0
If we take 330 away from 395, we end up with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 66

Moving on to step 6:
66 can be fit into 652 9 times, resulting in a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 5759.0
Deduct 594 from 652 and we're left with 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 66

Going ahead to step 7:
When dividing 586 by 66, we get 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 57598.0
The remainder is 58 after subtracting 528 from 586.
Append the next digit (1) from the dividend to 58 and continue with: 581 / 66

Let's proceed to step 8:
When dividing 581 by 66, we get 8 with a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 575988.0
If we take 528 away from 581, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
When dividing 530 by 66, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 575988.8
Subtracting 528 from 530 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 575988.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
When dividing 200 by 66, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 575988.803
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
When dividing 20 by 66, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 575988.803
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
200 divided by 66 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 575988.80303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
66 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 575988.80303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
If we divide 200 by 66, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 575988.8030303
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 16:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 575988.8030303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 575988.8030303 with a remaining 2e-08.
