66496442 divided by 625 
The aim is to understand the frequency of 625 in 66496442.

Going ahead to step 1:
625 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 625

Step 2:
625 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 625

Moving on to step 3:
625 can be fit into 664 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 625 from 664, we get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 625

Advancing to step 4:
625 can be fit into 399 0 times, resulting in a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 399 leaves us with 399.
Append the next digit (6) from the dividend to 399 and continue with: 3996 / 625

Let's proceed to step 5:
3996 divided by 625 is 6 with a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we subtract 3750 from 3996, we get 246.
Take the next digit (4) from the dividend and append it to 246, then repeat: 2464 / 625

Moving on to step 6:
625 can be fit into 2464 3 times, resulting in a remainder of 589.
Write down 3 as next digit of the result. 
Result so far: 1063.0
Subtracting 1875 from 2464 leaves us with 589.
Append the next digit (4) from the dividend to 589 and continue with: 5894 / 625

Advancing to step 7:
5894 divided by 625 is 9 with a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 10639.0
Subtract 5625 from 5894 to get 269.
Fetch the next digit (2) from the dividend, attach it to 269 and continue: 2692 / 625

Step 8:
625 goes into 2692 4 times with a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 106394.0
Deduct 2500 from 2692 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
If we divide 1920 by 625, we get 3 and a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 106394.3
If we take 1875 away from 1920, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
If we divide 450 by 625, we get 0 and a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 106394.3
Subtracting 0 from 450 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 11:
625 can be fit into 4500 7 times, resulting in a remainder of 125.
Write down 7 as next digit of the result. 
Result so far: 106394.307
Subtract 4375 from 4500 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
When dividing 1250 by 625, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 106394.3072
If we subtract 1250 from 1250, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 13:
0 divided by 625 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 106394.3072
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 14:
0 divided by 625 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 106394.3072
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 106394.3072, and the remainder is 0.0.
