We look at the division of 56738238 by 126 
The aim is to understand the frequency of 126 in 56738238.

Let's proceed to step 1:
When dividing 5 by 126, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 126

On to step 2:
When dividing 56 by 126, we get 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 126

Advancing to step 3:
The number 126 fits into 567 4 times, leaving a remainder of 63.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 63 after subtracting 504 from 567.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 126

Let's proceed to step 4:
126 goes into 633 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 3 after subtracting 630 from 633.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 126

Advancing to step 5:
When dividing 38 by 126, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 450.0
If we take 0 away from 38, we end up with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 126

Going ahead to step 6:
126 can be fit into 382 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 4503.0
Subtracting 378 from 382 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 126

Moving on to step 7:
43 divided by 126 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 45030.0
Subtract 0 from 43 to get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 126

Let's proceed to step 8:
If we divide 438 by 126, we get 3 and a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 450303.0
If we take 378 away from 438, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
126 can be fit into 600 4 times, resulting in a remainder of 96.
The next digit of our result is 4. 
Result so far: 450303.4
Deduct 504 from 600 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 10:
If we divide 960 by 126, we get 7 and a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 450303.47
Deduct 882 from 960 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
780 divided by 126 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 450303.476
Subtract 756 from 780 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
126 can be fit into 240 1 times, resulting in a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 450303.4761
The remainder is 114 after subtracting 126 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 13:
If we divide 1140 by 126, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 450303.47619
Subtracting 1134 from 1140 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
126 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 450303.47619
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 15:
The number 126 fits into 600 4 times, leaving a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 450303.4761904
The remainder is 96 after subtracting 504 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
960 divided by 126 is 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 450303.47619047
If we take 882 away from 960, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 450303.47619047 with a balance of 7.8e-08.
