Let's divide 43144903 by 642
The aim is to understand the frequency of 642 in 43144903.

Advancing to step 1:
4 divided by 642 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 642

Let's proceed to step 2:
642 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 642

On to step 3:
The number 642 fits into 431 0 times, leaving a remainder of 431.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 431 after subtracting 0 from 431.
Bring next digit (4) of the dividend behind the 431 and repeat the process: 4314 / 642

On to step 4:
When dividing 4314 by 642, we get 6 with a remainder of 462.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 462 after subtracting 3852 from 4314.
Take the next digit (4) from the dividend and append it to 462, then repeat: 4624 / 642

Moving on to step 5:
When dividing 4624 by 642, we get 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 67.0
The remainder is 130 after subtracting 4494 from 4624.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 642

Moving on to step 6:
642 goes into 1309 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 672.0
Subtracting 1284 from 1309 leaves us with 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 642

Moving on to step 7:
642 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 6720.0
Deduct 0 from 250 and we're left with 250.
Bring next digit (3) of the dividend behind the 250 and repeat the process: 2503 / 642

On to step 8:
The number 642 fits into 2503 3 times, leaving a remainder of 577.
The next digit of our result is 3. 
Result so far: 67203.0
If we subtract 1926 from 2503, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 9:
642 can be fit into 5770 8 times, resulting in a remainder of 634.
Write down 8 as next digit of the result. 
Result so far: 67203.8
If we take 5136 away from 5770, we end up with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

On to step 10:
If we divide 6340 by 642, we get 9 and a remainder of 562.
Put 9 as the next digit of the answer. 
Result so far: 67203.89
Subtracting 5778 from 6340 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 11:
The number 642 fits into 5620 8 times, leaving a remainder of 484.
The next digit of our result is 8. 
Result so far: 67203.898
Subtracting 5136 from 5620 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 12:
If we divide 4840 by 642, we get 7 and a remainder of 346.
Write down 7 as next digit of the result. 
Result so far: 67203.8987
Subtracting 4494 from 4840 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 13:
The number 642 fits into 3460 5 times, leaving a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 67203.89875
If we subtract 3210 from 3460, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
If we divide 2500 by 642, we get 3 and a remainder of 574.
The next digit of our result is 3. 
Result so far: 67203.898753
The remainder is 574 after subtracting 1926 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 15:
642 can be fit into 5740 8 times, resulting in a remainder of 604.
The number 8 becomes the next digit in our result. 
Result so far: 67203.8987538
Subtracting 5136 from 5740 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 16:
If we divide 6040 by 642, we get 9 and a remainder of 262.
Record the quotient 9 as the next digit in the result. 
Result so far: 67203.89875389
Deduct 5778 from 6040 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Our division results in 67203.89875389 with a remaining 2.62e-07.
