We're dividing 20117324 by 642 
The aim is to understand the frequency of 642 in 20117324.

Advancing to step 1:
642 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 642

Going ahead to step 2:
20 divided by 642 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 642

Step 3:
If we divide 201 by 642, we get 0 and a remainder of 201.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 201 leaves us with 201.
Grab the next digit (1) from the dividend, add it to 201, then carry on: 2011 / 642

Step 4:
When dividing 2011 by 642, we get 3 with a remainder of 85.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1926 from 2011 and we're left with 85.
Fetch the next digit (7) from the dividend, attach it to 85 and continue: 857 / 642

Moving on to step 5:
642 can be fit into 857 1 times, resulting in a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 642 from 857, we get 215.
Fetch the next digit (3) from the dividend, attach it to 215 and continue: 2153 / 642

Step 6:
If we divide 2153 by 642, we get 3 and a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Subtract 1926 from 2153 to get 227.
Include the next digit (2) from the dividend after 227, then repeat: 2272 / 642

Step 7:
2272 divided by 642 is 3 with a remainder of 346.
The number 3 becomes the next digit in our result. 
Result so far: 3133.0
If we take 1926 away from 2272, we end up with 346.
Fetch the next digit (4) from the dividend, attach it to 346 and continue: 3464 / 642

Let's proceed to step 8:
3464 divided by 642 is 5 with a remainder of 254.
Use 5 as the next digit of our solution. 
Result so far: 31335.0
If we take 3210 away from 3464, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 9:
642 goes into 2540 3 times with a remainder of 614.
Write down 3 as next digit of the result. 
Result so far: 31335.3
If we take 1926 away from 2540, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 10:
642 goes into 6140 9 times with a remainder of 362.
The next digit of our result is 9. 
Result so far: 31335.39
Subtract 5778 from 6140 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 11:
The number 642 fits into 3620 5 times, leaving a remainder of 410.
The next digit of our result is 5. 
Result so far: 31335.395
If we take 3210 away from 3620, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 12:
The number 642 fits into 4100 6 times, leaving a remainder of 248.
Use 6 as the next digit of our solution. 
Result so far: 31335.3956
Deduct 3852 from 4100 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 13:
If we divide 2480 by 642, we get 3 and a remainder of 554.
Record the quotient 3 as the next digit in the result. 
Result so far: 31335.39563
If we take 1926 away from 2480, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 14:
The number 642 fits into 5540 8 times, leaving a remainder of 404.
Write down 8 as next digit of the result. 
Result so far: 31335.395638
If we subtract 5136 from 5540, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 15:
If we divide 4040 by 642, we get 6 and a remainder of 188.
Use 6 as the next digit of our solution. 
Result so far: 31335.3956386
Subtracting 3852 from 4040 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 16:
When dividing 1880 by 642, we get 2 with a remainder of 596.
Write down 2 as next digit of the result. 
Result so far: 31335.39563862
Subtract 1284 from 1880 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

In conclusion, the division gives 31335.39563862 with a balance of 5.96e-07.
