We divide 73397489 by 666
The aim is to understand the frequency of 666 in 73397489.

Going ahead to step 1:
When dividing 7 by 666, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 666

Step 2:
666 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Fetch the next digit (3) from the dividend, attach it to 73 and continue: 733 / 666

On to step 3:
733 divided by 666 is 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 666 away from 733, we end up with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 666

Advancing to step 4:
If we divide 679 by 666, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 666 from 679 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 666

Let's proceed to step 5:
If we divide 137 by 666, we get 0 and a remainder of 137.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtract 0 from 137 to get 137.
Bring next digit (4) of the dividend behind the 137 and repeat the process: 1374 / 666

Let's proceed to step 6:
When dividing 1374 by 666, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 1102.0
If we subtract 1332 from 1374, we get 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 666

Let's proceed to step 7:
428 divided by 666 is 0 with a remainder of 428.
Write down 0 as next digit of the result. 
Result so far: 11020.0
Subtracting 0 from 428 leaves us with 428.
Include the next digit (9) from the dividend after 428, then repeat: 4289 / 666

Let's proceed to step 8:
The number 666 fits into 4289 6 times, leaving a remainder of 293.
The number 6 becomes the next digit in our result. 
Result so far: 110206.0
If we take 3996 away from 4289, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 9:
666 can be fit into 2930 4 times, resulting in a remainder of 266.
The next digit of our result is 4. 
Result so far: 110206.4
If we take 2664 away from 2930, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 10:
2660 divided by 666 is 3 with a remainder of 662.
The number 3 becomes the next digit in our result. 
Result so far: 110206.43
Subtracting 1998 from 2660 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Step 11:
666 goes into 6620 9 times with a remainder of 626.
The number 9 becomes the next digit in our result. 
Result so far: 110206.439
If we subtract 5994 from 6620, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Going ahead to step 12:
When dividing 6260 by 666, we get 9 with a remainder of 266.
Write down 9 as next digit of the result. 
Result so far: 110206.4399
Subtracting 5994 from 6260 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

The quotient of the division is 110206.4399, and the remainder is 0.00266.
