We look at the division of 72696701 by 642 
The aim is to understand the frequency of 642 in 72696701.

Going ahead to step 1:
If we divide 7 by 642, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 642

Advancing to step 2:
If we divide 72 by 642, we get 0 and a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 642

Going ahead to step 3:
726 divided by 642 is 1 with a remainder of 84.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 642 from 726 to get 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 642

Moving on to step 4:
642 can be fit into 849 1 times, resulting in a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 642 from 849 leaves us with 207.
Include the next digit (6) from the dividend after 207, then repeat: 2076 / 642

Advancing to step 5:
The number 642 fits into 2076 3 times, leaving a remainder of 150.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtracting 1926 from 2076 leaves us with 150.
Bring next digit (7) of the dividend behind the 150 and repeat the process: 1507 / 642

Step 6:
When dividing 1507 by 642, we get 2 with a remainder of 223.
The number 2 becomes the next digit in our result. 
Result so far: 1132.0
Subtract 1284 from 1507 to get 223.
Append the next digit (0) from the dividend to 223 and continue with: 2230 / 642

Going ahead to step 7:
642 can be fit into 2230 3 times, resulting in a remainder of 304.
The next digit of our result is 3. 
Result so far: 11323.0
If we take 1926 away from 2230, we end up with 304.
Bring next digit (1) of the dividend behind the 304 and repeat the process: 3041 / 642

On to step 8:
3041 divided by 642 is 4 with a remainder of 473.
Use 4 as the next digit of our solution. 
Result so far: 113234.0
If we subtract 2568 from 3041, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Moving on to step 9:
If we divide 4730 by 642, we get 7 and a remainder of 236.
The number 7 becomes the next digit in our result. 
Result so far: 113234.7
If we subtract 4494 from 4730, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
642 can be fit into 2360 3 times, resulting in a remainder of 434.
Use 3 as the next digit of our solution. 
Result so far: 113234.73
Deduct 1926 from 2360 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 11:
642 goes into 4340 6 times with a remainder of 488.
The number 6 becomes the next digit in our result. 
Result so far: 113234.736
Subtracting 3852 from 4340 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
If we divide 4880 by 642, we get 7 and a remainder of 386.
The next digit of our result is 7. 
Result so far: 113234.7367
If we take 4494 away from 4880, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 13:
642 can be fit into 3860 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 113234.73676
If we subtract 3852 from 3860, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
80 divided by 642 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 113234.73676
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
642 can be fit into 800 1 times, resulting in a remainder of 158.
Record the quotient 1 as the next digit in the result. 
Result so far: 113234.7367601
Subtract 642 from 800 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 16:
642 can be fit into 1580 2 times, resulting in a remainder of 296.
The next digit of our result is 2. 
Result so far: 113234.73676012
The remainder is 296 after subtracting 1284 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Our division results in 113234.73676012 with a remaining 2.96e-07.
