We divide 728115 by 42
We want to figure out the number of times 728115 can be divided by 42.

Let's proceed to step 1:
42 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 42

On to step 2:
42 can be fit into 72 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 72, we get 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 42

Let's proceed to step 3:
When dividing 308 by 42, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 294 from 308, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 42

On to step 4:
42 can be fit into 141 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Subtract 126 from 141 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 42

On to step 5:
When dividing 151 by 42, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 1733.0
Deduct 126 from 151 and we're left with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 42

Advancing to step 6:
The number 42 fits into 255 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 17336.0
Subtract 252 from 255 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 42, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 17336.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 17336.07
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 17336.071
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17336.0714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 17336.07142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
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: 17336.071428
Subtract 336 from 360 to 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.

Going ahead to step 13:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 17336.0714285
The remainder is 30 after subtracting 210 from 240.
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 14:
When dividing 300 by 42, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 17336.07142857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 17336.07142857, with a leftover of 6e-09.
