We divide 91809908 by 126
The aim is to understand the frequency of 126 in 91809908.

Going ahead to step 1:
The number 126 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 126

On to step 2:
The number 126 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 126

Moving on to step 3:
The number 126 fits into 918 7 times, leaving a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 882 away from 918, we end up with 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 126

Going ahead to step 4:
126 goes into 360 2 times with a remainder of 108.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 252 from 360 leaves us with 108.
Include the next digit (9) from the dividend after 108, then repeat: 1089 / 126

Going ahead to step 5:
126 goes into 1089 8 times with a remainder of 81.
Put 8 as the next digit of the answer. 
Result so far: 728.0
If we take 1008 away from 1089, we end up with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 126

Let's proceed to step 6:
The number 126 fits into 819 6 times, leaving a remainder of 63.
The next digit of our result is 6. 
Result so far: 7286.0
The remainder is 63 after subtracting 756 from 819.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 126

Advancing to step 7:
When dividing 630 by 126, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 72865.0
If we subtract 630 from 630, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 126

Advancing to step 8:
The number 126 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 728650.0
Deduct 0 from 8 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 126, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 728650.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
126 can be fit into 800 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 728650.06
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
126 goes into 440 3 times with a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 728650.063
Deduct 378 from 440 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
126 goes into 620 4 times with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 728650.0634
If we take 504 away from 620, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 13:
126 can be fit into 1160 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 728650.06349
Subtract 1134 from 1160 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
260 divided by 126 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 728650.063492
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 15:
80 divided by 126 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 728650.063492
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 16:
126 goes into 800 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 728650.06349206
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 728650.06349206 with a balance of 4.4e-08.
