1771333 ÷ 266 
The aim is to understand the frequency of 266 in 1771333.

Let's proceed to step 1:
When dividing 1 by 266, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 266

Advancing to step 2:
266 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 266

Step 3:
The number 266 fits into 177 0 times, leaving a remainder of 177.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 177, we get 177.
Take the next digit (1) from the dividend and append it to 177, then repeat: 1771 / 266

Moving on to step 4:
266 can be fit into 1771 6 times, resulting in a remainder of 175.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 175 after subtracting 1596 from 1771.
Bring next digit (3) of the dividend behind the 175 and repeat the process: 1753 / 266

Advancing to step 5:
266 can be fit into 1753 6 times, resulting in a remainder of 157.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 1596 from 1753 and we're left with 157.
Append the next digit (3) from the dividend to 157 and continue with: 1573 / 266

On to step 6:
1573 divided by 266 is 5 with a remainder of 243.
Write down 5 as next digit of the result. 
Result so far: 665.0
If we subtract 1330 from 1573, we get 243.
Append the next digit (3) from the dividend to 243 and continue with: 2433 / 266

Going ahead to step 7:
2433 divided by 266 is 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 6659.0
If we take 2394 away from 2433, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
When dividing 390 by 266, we get 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 6659.1
Deduct 266 from 390 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
When dividing 1240 by 266, we get 4 with a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 6659.14
Subtracting 1064 from 1240 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
1760 divided by 266 is 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 6659.146
If we take 1596 away from 1760, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 11:
The number 266 fits into 1640 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 6659.1466
Subtract 1596 from 1640 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 6659.1466 and a remainder of 0.00044.
