Let's divide 2019322 by 642
The aim is to understand the frequency of 642 in 2019322.

Going ahead to step 1:
When dividing 2 by 642, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 642

Moving on to step 2:
20 divided by 642 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 642

On to step 3:
201 divided by 642 is 0 with a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 201 and we're left with 201.
Append the next digit (9) from the dividend to 201 and continue with: 2019 / 642

Step 4:
642 can be fit into 2019 3 times, resulting in a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 93 after subtracting 1926 from 2019.
Take the next digit (3) from the dividend and append it to 93, then repeat: 933 / 642

Going ahead to step 5:
933 divided by 642 is 1 with a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 642 from 933 and we're left with 291.
Take the next digit (2) from the dividend and append it to 291, then repeat: 2912 / 642

On to step 6:
2912 divided by 642 is 4 with a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
If we take 2568 away from 2912, we end up with 344.
Take the next digit (2) from the dividend and append it to 344, then repeat: 3442 / 642

Going ahead to step 7:
642 goes into 3442 5 times with a remainder of 232.
The next digit of our result is 5. 
Result so far: 3145.0
If we subtract 3210 from 3442, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 8:
642 goes into 2320 3 times with a remainder of 394.
Write down 3 as next digit of the result. 
Result so far: 3145.3
If we take 1926 away from 2320, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 9:
642 can be fit into 3940 6 times, resulting in a remainder of 88.
The next digit of our result is 6. 
Result so far: 3145.36
Subtracting 3852 from 3940 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
When dividing 880 by 642, we get 1 with a remainder of 238.
Put 1 as the next digit of the answer. 
Result so far: 3145.361
Subtract 642 from 880 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 11:
If we divide 2380 by 642, we get 3 and a remainder of 454.
Write down 3 as next digit of the result. 
Result so far: 3145.3613
If we subtract 1926 from 2380, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 12:
The number 642 fits into 4540 7 times, leaving a remainder of 46.
The next digit of our result is 7. 
Result so far: 3145.36137
Subtracting 4494 from 4540 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
642 goes into 460 0 times with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 3145.36137
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 14:
4600 divided by 642 is 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 3145.3613707
Subtract 4494 from 4600 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 15:
The number 642 fits into 1060 1 times, leaving a remainder of 418.
Write down 1 as next digit of the result. 
Result so far: 3145.36137071
Deduct 642 from 1060 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 3145.36137071, with a leftover of 4.18e-07.
