11271526 ÷ 900 
The aim is to understand the frequency of 900 in 11271526.

Going ahead to step 1:
If we divide 1 by 900, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 900

Going ahead to step 2:
11 divided by 900 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 900

Let's proceed to step 3:
112 divided by 900 is 0 with a remainder of 112.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 112 and we're left with 112.
Grab the next digit (7) from the dividend, add it to 112, then carry on: 1127 / 900

On to step 4:
900 goes into 1127 1 times with a remainder of 227.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 227 after subtracting 900 from 1127.
Take the next digit (1) from the dividend and append it to 227, then repeat: 2271 / 900

On to step 5:
The number 900 fits into 2271 2 times, leaving a remainder of 471.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1800 from 2271 and we're left with 471.
Append the next digit (5) from the dividend to 471 and continue with: 4715 / 900

Moving on to step 6:
The number 900 fits into 4715 5 times, leaving a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtract 4500 from 4715 to get 215.
Fetch the next digit (2) from the dividend, attach it to 215 and continue: 2152 / 900

Step 7:
2152 divided by 900 is 2 with a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
Deduct 1800 from 2152 and we're left with 352.
Bring next digit (6) of the dividend behind the 352 and repeat the process: 3526 / 900

Advancing to step 8:
900 goes into 3526 3 times with a remainder of 826.
The number 3 becomes the next digit in our result. 
Result so far: 12523.0
If we subtract 2700 from 3526, we get 826.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8260, and continue the process.

Moving on to step 9:
900 can be fit into 8260 9 times, resulting in a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 12523.9
If we take 8100 away from 8260, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
The number 900 fits into 1600 1 times, leaving a remainder of 700.
Use 1 as the next digit of our solution. 
Result so far: 12523.91
If we take 900 away from 1600, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 11:
900 can be fit into 7000 7 times, resulting in a remainder of 700.
Write down 7 as next digit of the result. 
Result so far: 12523.917
If we take 6300 away from 7000, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 12:
900 can be fit into 7000 7 times, resulting in a remainder of 700.
Use 7 as the next digit of our solution. 
Result so far: 12523.9177
If we subtract 6300 from 7000, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 12523.9177 with a remainder of 0.007.
