42728223 ÷ 105 
We want to divide 42728223 by 105.

On to step 1:
When dividing 4 by 105, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 105

Moving on to step 2:
If we divide 42 by 105, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 105

Moving on to step 3:
If we divide 427 by 105, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 420 from 427 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 105

Going ahead to step 4:
105 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 105

Advancing to step 5:
When dividing 728 by 105, we get 6 with a remainder of 98.
Put 6 as the next digit of the answer. 
Result so far: 406.0
Subtracting 630 from 728 leaves us with 98.
Grab the next digit (2) from the dividend, add it to 98, then carry on: 982 / 105

Going ahead to step 6:
The number 105 fits into 982 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 4069.0
Subtracting 945 from 982 leaves us with 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 105

Going ahead to step 7:
372 divided by 105 is 3 with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 40693.0
If we take 315 away from 372, we end up with 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 105

Step 8:
105 can be fit into 573 5 times, resulting in a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 406935.0
Deduct 525 from 573 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 105, we get 4 and a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 406935.4
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
105 can be fit into 600 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 406935.45
Deduct 525 from 600 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
105 can be fit into 750 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 406935.457
The remainder is 15 after subtracting 735 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
105 can be fit into 150 1 times, resulting in a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 406935.4571
The remainder is 45 after subtracting 105 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
450 divided by 105 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 406935.45714
The remainder is 30 after subtracting 420 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
When dividing 300 by 105, we get 2 with a remainder of 90.
Use 2 as the next digit of our solution. 
Result so far: 406935.457142
The remainder is 90 after subtracting 210 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 15:
105 can be fit into 900 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 406935.4571428
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
105 can be fit into 600 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 406935.45714285
Deduct 525 from 600 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

In conclusion, the division gives 406935.45714285 with a balance of 7.5e-08.
