We look at the division of 23484944 by 126 
The aim is to understand the frequency of 126 in 23484944.

Advancing to step 1:
2 divided by 126 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 126

Step 2:
If we divide 23 by 126, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 126

Step 3:
126 can be fit into 234 1 times, resulting in a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 126 from 234 to get 108.
Grab the next digit (8) from the dividend, add it to 108, then carry on: 1088 / 126

Step 4:
1088 divided by 126 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 1008 from 1088, we get 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 126

On to step 5:
If we divide 804 by 126, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 186.0
Deduct 756 from 804 and we're left with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 126

Step 6:
The number 126 fits into 489 3 times, leaving a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 1863.0
If we take 378 away from 489, we end up with 111.
Bring next digit (4) of the dividend behind the 111 and repeat the process: 1114 / 126

On to step 7:
126 goes into 1114 8 times with a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 18638.0
Subtract 1008 from 1114 to get 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 126

Moving on to step 8:
126 goes into 1064 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 186388.0
Subtract 1008 from 1064 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
126 can be fit into 560 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 186388.4
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
126 goes into 560 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 186388.44
If we take 504 away from 560, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 186388.44 with a remainder of 0.056.
