Let's divide 4393546 by 126
The aim is to understand the frequency of 126 in 4393546.

Advancing to step 1:
4 divided by 126 is 0 with 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.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 126

Going ahead to step 2:
When dividing 43 by 126, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 126

Going ahead to step 3:
126 goes into 439 3 times with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 378 away from 439, we end up with 61.
Append the next digit (3) from the dividend to 61 and continue with: 613 / 126

Advancing to step 4:
126 can be fit into 613 4 times, resulting in a remainder of 109.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 504 from 613 leaves us with 109.
Append the next digit (5) from the dividend to 109 and continue with: 1095 / 126

Step 5:
126 goes into 1095 8 times with a remainder of 87.
The next digit of our result is 8. 
Result so far: 348.0
If we take 1008 away from 1095, we end up with 87.
Include the next digit (4) from the dividend after 87, then repeat: 874 / 126

Going ahead to step 6:
When dividing 874 by 126, we get 6 with a remainder of 118.
The next digit of our result is 6. 
Result so far: 3486.0
Subtract 756 from 874 to get 118.
Grab the next digit (6) from the dividend, add it to 118, then carry on: 1186 / 126

Going ahead to step 7:
1186 divided by 126 is 9 with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 34869.0
Subtracting 1134 from 1186 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
When dividing 520 by 126, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 34869.4
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 126 fits into 160 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 34869.41
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
126 goes into 340 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 34869.412
If we take 252 away from 340, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 11:
126 can be fit into 880 6 times, resulting in a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 34869.4126
Subtract 756 from 880 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 12:
126 goes into 1240 9 times with a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 34869.41269
If we subtract 1134 from 1240, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 13:
When dividing 1060 by 126, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 34869.412698
If we take 1008 away from 1060, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
126 goes into 520 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 34869.4126984
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 15:
126 goes into 160 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 34869.41269841
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 34869.41269841 with a remainder of 3.4e-08.
