42759987 ÷ 105 
Let's see how many times 105 fits into 42759987.

Step 1:
4 divided by 105 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 105

Moving on to step 2:
When dividing 42 by 105, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 105

Let's proceed to step 3:
If we divide 427 by 105, we get 4 and a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 7 after subtracting 420 from 427.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 105

Moving on to step 4:
105 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 75 to get 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 105

On to step 5:
When dividing 759 by 105, we get 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 407.0
Deduct 735 from 759 and we're left with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 105

Let's proceed to step 6:
If we divide 249 by 105, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 4072.0
Subtracting 210 from 249 leaves us with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 105

Step 7:
105 goes into 398 3 times with a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 40723.0
Subtract 315 from 398 to get 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 105

Let's proceed to step 8:
105 goes into 837 7 times with a remainder of 102.
The number 7 becomes the next digit in our result. 
Result so far: 407237.0
Deduct 735 from 837 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
The number 105 fits into 1020 9 times, leaving a remainder of 75.
The next digit of our result is 9. 
Result so far: 407237.9
If we take 945 away from 1020, we end up 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.

Advancing to step 10:
105 can be fit into 750 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 407237.97
If we subtract 735 from 750, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
150 divided by 105 is 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 407237.971
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.

On to step 12:
105 goes into 450 4 times with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 407237.9714
Deduct 420 from 450 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
105 can be fit into 300 2 times, resulting in a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 407237.97142
If we subtract 210 from 300, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 14:
The number 105 fits into 900 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 407237.971428
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
If we divide 600 by 105, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 407237.9714285
If we subtract 525 from 600, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 16:
105 can be fit into 750 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 407237.97142857
Deduct 735 from 750 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 407237.97142857, and the remainder is 1.5e-08.
