Let's divide 7432516 by 666
The aim is to understand the frequency of 666 in 7432516.

Moving on to step 1:
When dividing 7 by 666, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 666

Advancing to step 2:
When dividing 74 by 666, we get 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 666

On to step 3:
The number 666 fits into 743 1 times, leaving a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 666 from 743 leaves us with 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 666

Let's proceed to step 4:
666 goes into 772 1 times with a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 106 after subtracting 666 from 772.
Include the next digit (5) from the dividend after 106, then repeat: 1065 / 666

Let's proceed to step 5:
If we divide 1065 by 666, we get 1 and a remainder of 399.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we take 666 away from 1065, we end up with 399.
Fetch the next digit (1) from the dividend, attach it to 399 and continue: 3991 / 666

Going ahead to step 6:
666 goes into 3991 5 times with a remainder of 661.
Use 5 as the next digit of our solution. 
Result so far: 1115.0
Deduct 3330 from 3991 and we're left with 661.
Append the next digit (6) from the dividend to 661 and continue with: 6616 / 666

Let's proceed to step 7:
If we divide 6616 by 666, we get 9 and a remainder of 622.
The next digit of our result is 9. 
Result so far: 11159.0
Subtract 5994 from 6616 to get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 8:
If we divide 6220 by 666, we get 9 and a remainder of 226.
The next digit of our result is 9. 
Result so far: 11159.9
Subtract 5994 from 6220 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 9:
If we divide 2260 by 666, we get 3 and a remainder of 262.
Record the quotient 3 as the next digit in the result. 
Result so far: 11159.93
Subtract 1998 from 2260 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 10:
666 can be fit into 2620 3 times, resulting in a remainder of 622.
The number 3 becomes the next digit in our result. 
Result so far: 11159.933
If we take 1998 away from 2620, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

The final result is 11159.933 with a remainder of 0.0622.
