Let's divide 1406866 by 99
The aim is to understand the frequency of 99 in 1406866.

Advancing to step 1:
1 divided by 99 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 99

Going ahead to step 2:
The number 99 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 99

Advancing to step 3:
The number 99 fits into 140 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 99 from 140 and we're left with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 99

Advancing to step 4:
99 goes into 416 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 396 from 416 to get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 99

Let's proceed to step 5:
When dividing 208 by 99, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we subtract 198 from 208, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 99

Moving on to step 6:
99 can be fit into 106 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1421.0
If we subtract 99 from 106, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 99

On to step 7:
The number 99 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 14210.0
The remainder is 76 after subtracting 0 from 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
If we divide 760 by 99, we get 7 and a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 14210.7
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
670 divided by 99 is 6 with a remainder of 76.
The next digit of our result is 6. 
Result so far: 14210.76
If we take 594 away from 670, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
When dividing 760 by 99, we get 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 14210.767
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
670 divided by 99 is 6 with a remainder of 76.
The next digit of our result is 6. 
Result so far: 14210.7676
Deduct 594 from 670 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
99 goes into 760 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 14210.76767
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 13:
99 can be fit into 670 6 times, resulting in a remainder of 76.
The next digit of our result is 6. 
Result so far: 14210.767676
Subtract 594 from 670 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
99 can be fit into 760 7 times, resulting in a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 14210.7676767
Subtracting 693 from 760 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 15:
When dividing 670 by 99, we get 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 14210.76767676
If we take 594 away from 670, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 14210.76767676, with a leftover of 7.6e-08.
