We're dividing 48078650 by 126 
The aim is to understand the frequency of 126 in 48078650.

Step 1:
126 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 126

Step 2:
When dividing 48 by 126, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 126

Advancing to step 3:
The number 126 fits into 480 3 times, leaving a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 378 from 480, we get 102.
Append the next digit (7) from the dividend to 102 and continue with: 1027 / 126

Step 4:
1027 divided by 126 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 38.0
The remainder is 19 after subtracting 1008 from 1027.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 126

Advancing to step 5:
126 goes into 198 1 times with a remainder of 72.
The next digit of our result is 1. 
Result so far: 381.0
If we subtract 126 from 198, we get 72.
Bring next digit (6) of the dividend behind the 72 and repeat the process: 726 / 126

Going ahead to step 6:
126 goes into 726 5 times with a remainder of 96.
Put 5 as the next digit of the answer. 
Result so far: 3815.0
Subtract 630 from 726 to get 96.
Append the next digit (5) from the dividend to 96 and continue with: 965 / 126

Let's proceed to step 7:
The number 126 fits into 965 7 times, leaving a remainder of 83.
The next digit of our result is 7. 
Result so far: 38157.0
If we subtract 882 from 965, we get 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 126

Moving on to step 8:
When dividing 830 by 126, we get 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 381576.0
Deduct 756 from 830 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
When dividing 740 by 126, we get 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 381576.5
If we take 630 away from 740, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
126 can be fit into 1100 8 times, resulting in a remainder of 92.
Use 8 as the next digit of our solution. 
Result so far: 381576.58
Deduct 1008 from 1100 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 11:
When dividing 920 by 126, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 381576.587
The remainder is 38 after subtracting 882 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
If we divide 380 by 126, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 381576.5873
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
20 divided by 126 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 381576.5873
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
If we divide 200 by 126, we get 1 and a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 381576.587301
The remainder is 74 after subtracting 126 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 15:
126 can be fit into 740 5 times, resulting in a remainder of 110.
The next digit of our result is 5. 
Result so far: 381576.5873015
Subtract 630 from 740 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
The number 126 fits into 1100 8 times, leaving a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 381576.58730158
The remainder is 92 after subtracting 1008 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 381576.58730158, with a leftover of 9.2e-08.
