We divide 40559698 by 666
The aim is to understand the frequency of 666 in 40559698.

Let's proceed to step 1:
666 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 666

Let's proceed to step 2:
When dividing 40 by 666, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 666

Advancing to step 3:
666 can be fit into 405 0 times, resulting in a remainder of 405.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 405 to get 405.
Grab the next digit (5) from the dividend, add it to 405, then carry on: 4055 / 666

Moving on to step 4:
The number 666 fits into 4055 6 times, leaving a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 3996 away from 4055, we end up with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 666

On to step 5:
When dividing 599 by 666, we get 0 with a remainder of 599.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we take 0 away from 599, we end up with 599.
Bring next digit (6) of the dividend behind the 599 and repeat the process: 5996 / 666

Moving on to step 6:
5996 divided by 666 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 609.0
If we subtract 5994 from 5996, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 666

Advancing to step 7:
If we divide 29 by 666, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 6090.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 666

On to step 8:
If we divide 298 by 666, we get 0 and a remainder of 298.
Put 0 as the next digit of the answer. 
Result so far: 60900.0
Subtract 0 from 298 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Moving on to step 9:
2980 divided by 666 is 4 with a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 60900.4
Subtract 2664 from 2980 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
When dividing 3160 by 666, we get 4 with a remainder of 496.
Put 4 as the next digit of the answer. 
Result so far: 60900.44
The remainder is 496 after subtracting 2664 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The quotient of the division is 60900.44, and the remainder is 0.496.
