We're dividing 72549947 by 126 
The aim is to understand the frequency of 126 in 72549947.

Going ahead to step 1:
If we divide 7 by 126, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 126

Let's proceed to step 2:
When dividing 72 by 126, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 126

On to step 3:
When dividing 725 by 126, we get 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 95 after subtracting 630 from 725.
Append the next digit (4) from the dividend to 95 and continue with: 954 / 126

Moving on to step 4:
954 divided by 126 is 7 with a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 72 after subtracting 882 from 954.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 126

Let's proceed to step 5:
If we divide 729 by 126, we get 5 and a remainder of 99.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
If we subtract 630 from 729, we get 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 126

Step 6:
When dividing 999 by 126, we get 7 with a remainder of 117.
The next digit of our result is 7. 
Result so far: 5757.0
The remainder is 117 after subtracting 882 from 999.
Take the next digit (4) from the dividend and append it to 117, then repeat: 1174 / 126

Advancing to step 7:
When dividing 1174 by 126, we get 9 with a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 57579.0
If we take 1134 away from 1174, we end up with 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 126

Let's proceed to step 8:
126 can be fit into 407 3 times, resulting in a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 575793.0
Deduct 378 from 407 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
When dividing 290 by 126, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 575793.2
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
380 divided by 126 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 575793.23
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
If we divide 20 by 126, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 575793.23
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.

Advancing to step 12:
If we divide 200 by 126, we get 1 and a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 575793.2301
Deduct 126 from 200 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.

On to step 13:
740 divided by 126 is 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 575793.23015
If we subtract 630 from 740, we 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.

Moving on to step 14:
If we divide 1100 by 126, we get 8 and a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 575793.230158
If we take 1008 away from 1100, we end up 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 15:
When dividing 920 by 126, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 575793.2301587
Deduct 882 from 920 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 16:
If we divide 380 by 126, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 575793.23015873
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 575793.23015873 with a remainder of 2e-09.
