744729 divided by 42 
Our goal is to divide 744729 by 42.

On to step 1:
The number 42 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 42

Advancing to step 2:
If we divide 74 by 42, we get 1 and a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 42 away from 74, we end up with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 42

Let's proceed to step 3:
When dividing 324 by 42, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 294 away from 324, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 42

Advancing to step 4:
307 divided by 42 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 177.0
If we take 294 away from 307, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 42

On to step 5:
If we divide 132 by 42, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1773.0
Subtract 126 from 132 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 42

Step 6:
69 divided by 42 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 17731.0
If we take 42 away from 69, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
The number 42 fits into 270 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 17731.6
The remainder is 18 after subtracting 252 from 270.
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 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 17731.64
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 42 fits into 120 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 17731.642
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
When dividing 360 by 42, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 17731.6428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 42 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 17731.64285
If we take 210 away from 240, we end up 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.

Going ahead to step 12:
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: 17731.642857
If we take 294 away from 300, we end up 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.

Step 13:
42 goes into 60 1 times with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 17731.6428571
If we take 42 away from 60, we end up with 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 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 17731.64285714
Subtracting 168 from 180 leaves us 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.

The final result is 17731.64285714 with a remainder of 1.2e-08.
