We're dividing 99889042 by 912 
The aim is to understand the frequency of 912 in 99889042.

Let's proceed to step 1:
The number 912 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 912

Advancing to step 2:
912 can be fit into 99 0 times, resulting in a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Grab the next digit (8) from the dividend, add it to 99, then carry on: 998 / 912

Let's proceed to step 3:
The number 912 fits into 998 1 times, leaving a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 912 from 998 leaves us with 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 912

Moving on to step 4:
The number 912 fits into 868 0 times, leaving a remainder of 868.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 868 to get 868.
Take the next digit (9) from the dividend and append it to 868, then repeat: 8689 / 912

Moving on to step 5:
If we divide 8689 by 912, we get 9 and a remainder of 481.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
The remainder is 481 after subtracting 8208 from 8689.
Grab the next digit (0) from the dividend, add it to 481, then carry on: 4810 / 912

Step 6:
If we divide 4810 by 912, we get 5 and a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 1095.0
If we take 4560 away from 4810, we end up with 250.
Fetch the next digit (4) from the dividend, attach it to 250 and continue: 2504 / 912

On to step 7:
If we divide 2504 by 912, we get 2 and a remainder of 680.
The next digit of our result is 2. 
Result so far: 10952.0
Subtract 1824 from 2504 to get 680.
Fetch the next digit (2) from the dividend, attach it to 680 and continue: 6802 / 912

Step 8:
If we divide 6802 by 912, we get 7 and a remainder of 418.
Use 7 as the next digit of our solution. 
Result so far: 109527.0
If we take 6384 away from 6802, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 9:
912 can be fit into 4180 4 times, resulting in a remainder of 532.
The number 4 becomes the next digit in our result. 
Result so far: 109527.4
If we take 3648 away from 4180, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 10:
If we divide 5320 by 912, we get 5 and a remainder of 760.
Put 5 as the next digit of the answer. 
Result so far: 109527.45
Subtracting 4560 from 5320 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 11:
912 goes into 7600 8 times with a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 109527.458
If we take 7296 away from 7600, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 12:
912 can be fit into 3040 3 times, resulting in a remainder of 304.
The next digit of our result is 3. 
Result so far: 109527.4583
If we take 2736 away from 3040, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
If we divide 3040 by 912, we get 3 and a remainder of 304.
Record the quotient 3 as the next digit in the result. 
Result so far: 109527.45833
Deduct 2736 from 3040 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

After the division, we end up with 109527.45833 and a remainder of 0.000304.
