We're dividing 44429534 by 660 
The aim is to understand the frequency of 660 in 44429534.

Step 1:
4 divided by 660 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 660

Let's proceed to step 2:
When dividing 44 by 660, we get 0 with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 660

Step 3:
660 goes into 444 0 times with a remainder of 444.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 444 to get 444.
Include the next digit (2) from the dividend after 444, then repeat: 4442 / 660

Moving on to step 4:
4442 divided by 660 is 6 with a remainder of 482.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3960 from 4442 and we're left with 482.
Include the next digit (9) from the dividend after 482, then repeat: 4829 / 660

Let's proceed to step 5:
660 goes into 4829 7 times with a remainder of 209.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Deduct 4620 from 4829 and we're left with 209.
Append the next digit (5) from the dividend to 209 and continue with: 2095 / 660

Let's proceed to step 6:
660 goes into 2095 3 times with a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 673.0
Deduct 1980 from 2095 and we're left with 115.
Grab the next digit (3) from the dividend, add it to 115, then carry on: 1153 / 660

Moving on to step 7:
1153 divided by 660 is 1 with a remainder of 493.
Write down 1 as next digit of the result. 
Result so far: 6731.0
Deduct 660 from 1153 and we're left with 493.
Grab the next digit (4) from the dividend, add it to 493, then carry on: 4934 / 660

Moving on to step 8:
When dividing 4934 by 660, we get 7 with a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 67317.0
The remainder is 314 after subtracting 4620 from 4934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 9:
The number 660 fits into 3140 4 times, leaving a remainder of 500.
Record the quotient 4 as the next digit in the result. 
Result so far: 67317.4
The remainder is 500 after subtracting 2640 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 10:
If we divide 5000 by 660, we get 7 and a remainder of 380.
Record the quotient 7 as the next digit in the result. 
Result so far: 67317.47
Deduct 4620 from 5000 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
660 can be fit into 3800 5 times, resulting in a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 67317.475
If we subtract 3300 from 3800, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 12:
660 can be fit into 5000 7 times, resulting in a remainder of 380.
Use 7 as the next digit of our solution. 
Result so far: 67317.4757
Subtract 4620 from 5000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
When dividing 3800 by 660, we get 5 with a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 67317.47575
Deduct 3300 from 3800 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 14:
5000 divided by 660 is 7 with a remainder of 380.
Put 7 as the next digit of the answer. 
Result so far: 67317.475757
Subtract 4620 from 5000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 15:
The number 660 fits into 3800 5 times, leaving a remainder of 500.
The next digit of our result is 5. 
Result so far: 67317.4757575
If we take 3300 away from 3800, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 16:
5000 divided by 660 is 7 with a remainder of 380.
The number 7 becomes the next digit in our result. 
Result so far: 67317.47575757
Deduct 4620 from 5000 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

After the division, we end up with 67317.47575757 and a remainder of 3.8e-07.
