We look at the division of 69597760 by 126 
The aim is to understand the frequency of 126 in 69597760.

Moving on to step 1:
126 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 126

Step 2:
69 divided by 126 is 0 with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 126

Advancing to step 3:
When dividing 695 by 126, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 630 from 695 and we're left with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 126

Moving on to step 4:
126 can be fit into 659 5 times, resulting in a remainder of 29.
The next digit of our result is 5. 
Result so far: 55.0
If we take 630 away from 659, we end up with 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 126

Moving on to step 5:
If we divide 297 by 126, we get 2 and a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 552.0
Subtracting 252 from 297 leaves us with 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 126

Going ahead to step 6:
457 divided by 126 is 3 with a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 5523.0
The remainder is 79 after subtracting 378 from 457.
Include the next digit (6) from the dividend after 79, then repeat: 796 / 126

Step 7:
The number 126 fits into 796 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 55236.0
Subtract 756 from 796 to get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 126

Moving on to step 8:
When dividing 400 by 126, we get 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 552363.0
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
126 can be fit into 220 1 times, resulting in a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 552363.1
The remainder is 94 after subtracting 126 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
126 can be fit into 940 7 times, resulting in a remainder of 58.
The next digit of our result is 7. 
Result so far: 552363.17
If we take 882 away from 940, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
126 goes into 580 4 times with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 552363.174
If we take 504 away from 580, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
126 can be fit into 760 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 552363.1746
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
The number 126 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 552363.1746
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
If we divide 400 by 126, we get 3 and a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 552363.174603
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 15:
When dividing 220 by 126, we get 1 with a remainder of 94.
Write down 1 as next digit of the result. 
Result so far: 552363.1746031
Deduct 126 from 220 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 16:
If we divide 940 by 126, we get 7 and a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 552363.17460317
Deduct 882 from 940 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 552363.17460317, with a leftover of 5.8e-08.
