12427669 divided by 899 
The aim is to understand the frequency of 899 in 12427669.

On to step 1:
899 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 899

Step 2:
899 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 899

Step 3:
899 goes into 124 0 times with a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 124 and we're left with 124.
Append the next digit (2) from the dividend to 124 and continue with: 1242 / 899

Step 4:
The number 899 fits into 1242 1 times, leaving a remainder of 343.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 343 after subtracting 899 from 1242.
Bring next digit (7) of the dividend behind the 343 and repeat the process: 3437 / 899

Going ahead to step 5:
3437 divided by 899 is 3 with a remainder of 740.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2697 from 3437 leaves us with 740.
Include the next digit (6) from the dividend after 740, then repeat: 7406 / 899

Going ahead to step 6:
The number 899 fits into 7406 8 times, leaving a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 138.0
If we subtract 7192 from 7406, we get 214.
Grab the next digit (6) from the dividend, add it to 214, then carry on: 2146 / 899

Let's proceed to step 7:
If we divide 2146 by 899, we get 2 and a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 1382.0
Deduct 1798 from 2146 and we're left with 348.
Include the next digit (9) from the dividend after 348, then repeat: 3489 / 899

On to step 8:
3489 divided by 899 is 3 with a remainder of 792.
Write down 3 as next digit of the result. 
Result so far: 13823.0
The remainder is 792 after subtracting 2697 from 3489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Moving on to step 9:
When dividing 7920 by 899, we get 8 with a remainder of 728.
Write down 8 as next digit of the result. 
Result so far: 13823.8
If we subtract 7192 from 7920, we get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Advancing to step 10:
899 can be fit into 7280 8 times, resulting in a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 13823.88
Deduct 7192 from 7280 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 13823.88, and the remainder is 0.088.
