738879 ÷ 42 
Let's see how many times 42 fits into 738879.

Going ahead to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 42

On to step 2:
42 can be fit into 73 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 73 to get 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 42

Step 3:
When dividing 318 by 42, we get 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 294 from 318, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 42

Going ahead to step 4:
If we divide 248 by 42, we get 5 and a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we take 210 away from 248, we end up with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 42

On to step 5:
If we divide 387 by 42, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 1759.0
Deduct 378 from 387 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 42

Step 6:
99 divided by 42 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 17592.0
Subtracting 84 from 99 leaves us 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.

Going ahead to step 7:
If we divide 150 by 42, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 17592.3
If we subtract 126 from 150, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
When dividing 240 by 42, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 17592.35
Subtracting 210 from 240 leaves us 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.

Moving on to step 9:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 17592.357
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 17592.3571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 17592.35714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
42 goes into 120 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 17592.357142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 17592.3571428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 42 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 17592.35714285
Deduct 210 from 240 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.

The final outcome is 17592.35714285, with a leftover of 3e-08.
