Let's divide 12228891 by 889
The aim is to understand the frequency of 889 in 12228891.

Let's proceed to step 1:
The number 889 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 889

Advancing to step 2:
889 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 889

Advancing to step 3:
When dividing 122 by 889, we get 0 with a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Grab the next digit (2) from the dividend, add it to 122, then carry on: 1222 / 889

Step 4:
889 goes into 1222 1 times with a remainder of 333.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 889 from 1222 leaves us with 333.
Fetch the next digit (8) from the dividend, attach it to 333 and continue: 3338 / 889

Advancing to step 5:
889 goes into 3338 3 times with a remainder of 671.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 2667 from 3338 to get 671.
Take the next digit (8) from the dividend and append it to 671, then repeat: 6718 / 889

Step 6:
The number 889 fits into 6718 7 times, leaving a remainder of 495.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtracting 6223 from 6718 leaves us with 495.
Fetch the next digit (9) from the dividend, attach it to 495 and continue: 4959 / 889

Step 7:
889 can be fit into 4959 5 times, resulting in a remainder of 514.
Record the quotient 5 as the next digit in the result. 
Result so far: 1375.0
Deduct 4445 from 4959 and we're left with 514.
Fetch the next digit (1) from the dividend, attach it to 514 and continue: 5141 / 889

Let's proceed to step 8:
889 goes into 5141 5 times with a remainder of 696.
The number 5 becomes the next digit in our result. 
Result so far: 13755.0
If we take 4445 away from 5141, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 9:
When dividing 6960 by 889, we get 7 with a remainder of 737.
The next digit of our result is 7. 
Result so far: 13755.7
The remainder is 737 after subtracting 6223 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

On to step 10:
If we divide 7370 by 889, we get 8 and a remainder of 258.
Use 8 as the next digit of our solution. 
Result so far: 13755.78
Subtract 7112 from 7370 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 11:
If we divide 2580 by 889, we get 2 and a remainder of 802.
The number 2 becomes the next digit in our result. 
Result so far: 13755.782
If we take 1778 away from 2580, we end up with 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Step 12:
889 goes into 8020 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 13755.7829
Subtracting 8001 from 8020 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
889 can be fit into 190 0 times, resulting in a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 13755.7829
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 14:
889 can be fit into 1900 2 times, resulting in a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 13755.782902
Subtract 1778 from 1900 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 15:
889 goes into 1220 1 times with a remainder of 331.
The next digit of our result is 1. 
Result so far: 13755.7829021
If we take 889 away from 1220, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 16:
If we divide 3310 by 889, we get 3 and a remainder of 643.
Record the quotient 3 as the next digit in the result. 
Result so far: 13755.78290213
Subtract 2667 from 3310 to get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

The final outcome is 13755.78290213, with a leftover of 6.43e-07.
