50814361 divided by 642 
The aim is to understand the frequency of 642 in 50814361.

Step 1:
When dividing 5 by 642, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 642

Moving on to step 2:
When dividing 50 by 642, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 642

Going ahead to step 3:
642 can be fit into 508 0 times, resulting in a remainder of 508.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 508 to get 508.
Append the next digit (1) from the dividend to 508 and continue with: 5081 / 642

Moving on to step 4:
642 goes into 5081 7 times with a remainder of 587.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 587 after subtracting 4494 from 5081.
Include the next digit (4) from the dividend after 587, then repeat: 5874 / 642

Moving on to step 5:
If we divide 5874 by 642, we get 9 and a remainder of 96.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 5778 from 5874, we get 96.
Include the next digit (3) from the dividend after 96, then repeat: 963 / 642

Step 6:
642 can be fit into 963 1 times, resulting in a remainder of 321.
The next digit of our result is 1. 
Result so far: 791.0
The remainder is 321 after subtracting 642 from 963.
Bring next digit (6) of the dividend behind the 321 and repeat the process: 3216 / 642

Advancing to step 7:
642 can be fit into 3216 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 7915.0
Subtracting 3210 from 3216 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 642

On to step 8:
When dividing 61 by 642, we get 0 with a remainder of 61.
The number 0 becomes the next digit in our result. 
Result so far: 79150.0
Subtract 0 from 61 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
When dividing 610 by 642, we get 0 with a remainder of 610.
Use 0 as the next digit of our solution. 
Result so far: 79150.0
The remainder is 610 after subtracting 0 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 10:
6100 divided by 642 is 9 with a remainder of 322.
Use 9 as the next digit of our solution. 
Result so far: 79150.09
Deduct 5778 from 6100 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 11:
642 goes into 3220 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 79150.095
The remainder is 10 after subtracting 3210 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
The number 642 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 79150.095
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
When dividing 1000 by 642, we get 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 79150.09501
The remainder is 358 after subtracting 642 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 14:
642 can be fit into 3580 5 times, resulting in a remainder of 370.
Put 5 as the next digit of the answer. 
Result so far: 79150.095015
Subtracting 3210 from 3580 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 15:
The number 642 fits into 3700 5 times, leaving a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 79150.0950155
If we take 3210 away from 3700, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 79150.0950155 with a balance of 4.9e-06.
