We divide 3880071 by 642
The aim is to understand the frequency of 642 in 3880071.

Step 1:
642 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 642

Moving on to step 2:
The number 642 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 642

On to step 3:
388 divided by 642 is 0 with a remainder of 388.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 388 leaves us with 388.
Grab the next digit (0) from the dividend, add it to 388, then carry on: 3880 / 642

Moving on to step 4:
642 can be fit into 3880 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 3852 from 3880 and we're left with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 642

Advancing to step 5:
642 can be fit into 280 0 times, resulting in a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we subtract 0 from 280, we get 280.
Append the next digit (7) from the dividend to 280 and continue with: 2807 / 642

On to step 6:
642 goes into 2807 4 times with a remainder of 239.
Record the quotient 4 as the next digit in the result. 
Result so far: 604.0
Deduct 2568 from 2807 and we're left with 239.
Append the next digit (1) from the dividend to 239 and continue with: 2391 / 642

Advancing to step 7:
When dividing 2391 by 642, we get 3 with a remainder of 465.
The next digit of our result is 3. 
Result so far: 6043.0
Deduct 1926 from 2391 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 8:
4650 divided by 642 is 7 with a remainder of 156.
The next digit of our result is 7. 
Result so far: 6043.7
Subtract 4494 from 4650 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
642 can be fit into 1560 2 times, resulting in a remainder of 276.
Use 2 as the next digit of our solution. 
Result so far: 6043.72
If we subtract 1284 from 1560, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 10:
The number 642 fits into 2760 4 times, leaving a remainder of 192.
The next digit of our result is 4. 
Result so far: 6043.724
The remainder is 192 after subtracting 2568 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 11:
1920 divided by 642 is 2 with a remainder of 636.
Use 2 as the next digit of our solution. 
Result so far: 6043.7242
Subtract 1284 from 1920 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 12:
If we divide 6360 by 642, we get 9 and a remainder of 582.
Write down 9 as next digit of the result. 
Result so far: 6043.72429
If we subtract 5778 from 6360, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 13:
The number 642 fits into 5820 9 times, leaving a remainder of 42.
The next digit of our result is 9. 
Result so far: 6043.724299
Subtracting 5778 from 5820 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 6043.724299 with a remaining 4.2e-06.
