We look at the division of 2507413 by 266 
The aim is to understand the frequency of 266 in 2507413.

Advancing to step 1:
266 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 266

Step 2:
The number 266 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 266

Let's proceed to step 3:
266 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 250 to get 250.
Append the next digit (7) from the dividend to 250 and continue with: 2507 / 266

Step 4:
The number 266 fits into 2507 9 times, leaving a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 2394 from 2507 to get 113.
Append the next digit (4) from the dividend to 113 and continue with: 1134 / 266

Going ahead to step 5:
The number 266 fits into 1134 4 times, leaving a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 94.0
Deduct 1064 from 1134 and we're left with 70.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 266

Moving on to step 6:
The number 266 fits into 701 2 times, leaving a remainder of 169.
Record the quotient 2 as the next digit in the result. 
Result so far: 942.0
If we take 532 away from 701, we end up with 169.
Fetch the next digit (3) from the dividend, attach it to 169 and continue: 1693 / 266

On to step 7:
266 goes into 1693 6 times with a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 9426.0
If we subtract 1596 from 1693, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 8:
266 goes into 970 3 times with a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 9426.3
Deduct 798 from 970 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 9:
The number 266 fits into 1720 6 times, leaving a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 9426.36
If we subtract 1596 from 1720, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
When dividing 1240 by 266, we get 4 with a remainder of 176.
The next digit of our result is 4. 
Result so far: 9426.364
If we subtract 1064 from 1240, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 11:
The number 266 fits into 1760 6 times, leaving a remainder of 164.
The next digit of our result is 6. 
Result so far: 9426.3646
The remainder is 164 after subtracting 1596 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 12:
When dividing 1640 by 266, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 9426.36466
Subtracting 1596 from 1640 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 9426.36466, and the remainder is 4.4e-05.
