90310349 divided by 266 
The aim is to understand the frequency of 266 in 90310349.

On to step 1:
266 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 266

Advancing to step 2:
The number 266 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 266

Moving on to step 3:
266 can be fit into 903 3 times, resulting in a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 798 from 903 and we're left with 105.
Take the next digit (1) from the dividend and append it to 105, then repeat: 1051 / 266

Going ahead to step 4:
The number 266 fits into 1051 3 times, leaving a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 798 from 1051, we get 253.
Take the next digit (0) from the dividend and append it to 253, then repeat: 2530 / 266

Step 5:
266 can be fit into 2530 9 times, resulting in a remainder of 136.
Put 9 as the next digit of the answer. 
Result so far: 339.0
If we take 2394 away from 2530, we end up with 136.
Take the next digit (3) from the dividend and append it to 136, then repeat: 1363 / 266

Advancing to step 6:
When dividing 1363 by 266, we get 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 3395.0
If we take 1330 away from 1363, we end up with 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 266

Step 7:
334 divided by 266 is 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 33951.0
The remainder is 68 after subtracting 266 from 334.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 266

Going ahead to step 8:
The number 266 fits into 689 2 times, leaving a remainder of 157.
Put 2 as the next digit of the answer. 
Result so far: 339512.0
Subtract 532 from 689 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
1570 divided by 266 is 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 339512.5
Subtracting 1330 from 1570 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
2400 divided by 266 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 339512.59
If we subtract 2394 from 2400, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
When dividing 60 by 266, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 339512.59
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 266, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 339512.5902
If we subtract 532 from 600, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
If we divide 680 by 266, we get 2 and a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 339512.59022
The remainder is 148 after subtracting 532 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Our division results in 339512.59022 with a remaining 0.000148.
