Let's divide 66872008 by 440
The aim is to understand the frequency of 440 in 66872008.

Step 1:
The number 440 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 440

Step 2:
If we divide 66 by 440, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 440

Moving on to step 3:
The number 440 fits into 668 1 times, leaving a remainder of 228.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 440 from 668, we get 228.
Include the next digit (7) from the dividend after 228, then repeat: 2287 / 440

Advancing to step 4:
2287 divided by 440 is 5 with a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 2200 from 2287 leaves us with 87.
Bring next digit (2) of the dividend behind the 87 and repeat the process: 872 / 440

Let's proceed to step 5:
If we divide 872 by 440, we get 1 and a remainder of 432.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we subtract 440 from 872, we get 432.
Include the next digit (0) from the dividend after 432, then repeat: 4320 / 440

Moving on to step 6:
If we divide 4320 by 440, we get 9 and a remainder of 360.
Put 9 as the next digit of the answer. 
Result so far: 1519.0
Deduct 3960 from 4320 and we're left with 360.
Include the next digit (0) from the dividend after 360, then repeat: 3600 / 440

Let's proceed to step 7:
If we divide 3600 by 440, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 15198.0
If we subtract 3520 from 3600, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 440

On to step 8:
The number 440 fits into 808 1 times, leaving a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 151981.0
Subtracting 440 from 808 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 9:
If we divide 3680 by 440, we get 8 and a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 151981.8
If we take 3520 away from 3680, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
440 goes into 1600 3 times with a remainder of 280.
The number 3 becomes the next digit in our result. 
Result so far: 151981.83
If we take 1320 away from 1600, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
When dividing 2800 by 440, we get 6 with a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 151981.836
Subtracting 2640 from 2800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
440 goes into 1600 3 times with a remainder of 280.
Record the quotient 3 as the next digit in the result. 
Result so far: 151981.8363
If we subtract 1320 from 1600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 13:
If we divide 2800 by 440, we get 6 and a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 151981.83636
Subtracting 2640 from 2800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
1600 divided by 440 is 3 with a remainder of 280.
Put 3 as the next digit of the answer. 
Result so far: 151981.836363
Subtracting 1320 from 1600 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
440 can be fit into 2800 6 times, resulting in a remainder of 160.
The next digit of our result is 6. 
Result so far: 151981.8363636
Subtracting 2640 from 2800 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 16:
440 goes into 1600 3 times with a remainder of 280.
The number 3 becomes the next digit in our result. 
Result so far: 151981.83636363
Deduct 1320 from 1600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 151981.83636363, with a leftover of 2.8e-07.
