Let's divide 77085689 by 126
The aim is to understand the frequency of 126 in 77085689.

Advancing to step 1:
126 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 126

Moving on to step 2:
If we divide 77 by 126, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 126

Moving on to step 3:
126 goes into 770 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 14 after subtracting 756 from 770.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 126

Step 4:
126 can be fit into 148 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
If we subtract 126 from 148, we get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 126

Advancing to step 5:
126 can be fit into 225 1 times, resulting in a remainder of 99.
The number 1 becomes the next digit in our result. 
Result so far: 611.0
Subtract 126 from 225 to get 99.
Append the next digit (6) from the dividend to 99 and continue with: 996 / 126

On to step 6:
996 divided by 126 is 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 6117.0
If we subtract 882 from 996, we get 114.
Include the next digit (8) from the dividend after 114, then repeat: 1148 / 126

Let's proceed to step 7:
The number 126 fits into 1148 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 61179.0
If we subtract 1134 from 1148, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 126

Going ahead to step 8:
149 divided by 126 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 611791.0
The remainder is 23 after subtracting 126 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
126 goes into 230 1 times with a remainder of 104.
Write down 1 as next digit of the result. 
Result so far: 611791.1
Subtracting 126 from 230 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
126 goes into 1040 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 611791.18
If we take 1008 away from 1040, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 11:
If we divide 320 by 126, we get 2 and a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 611791.182
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
680 divided by 126 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 611791.1825
If we take 630 away from 680, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
126 goes into 500 3 times with a remainder of 122.
The next digit of our result is 3. 
Result so far: 611791.18253
If we take 378 away from 500, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 14:
126 goes into 1220 9 times with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 611791.182539
If we subtract 1134 from 1220, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 15:
When dividing 860 by 126, we get 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 611791.1825396
If we subtract 756 from 860, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 16:
126 goes into 1040 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 611791.18253968
The remainder is 32 after subtracting 1008 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 611791.18253968 with a remainder of 3.2e-08.
