We divide 749307 by 42
Our goal is to divide 749307 by 42.

On to step 1:
7 divided by 42 is 0 with 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.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 42

Moving on to step 2:
42 can be fit into 74 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 74, we get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 42

On to step 3:
The number 42 fits into 329 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 294 from 329, we get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 42

Advancing to step 4:
42 goes into 353 8 times with a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 17 after subtracting 336 from 353.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 42

Let's proceed to step 5:
When dividing 170 by 42, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1784.0
Subtract 168 from 170 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 42

Going ahead to step 6:
27 divided by 42 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 17840.0
Deduct 0 from 27 and we're left 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.

Going ahead to step 7:
The number 42 fits into 270 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 17840.6
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.

Let's proceed to step 8:
When dividing 180 by 42, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 17840.64
If we take 168 away from 180, we end up 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.

Step 9:
120 divided by 42 is 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 17840.642
Deduct 84 from 120 and we're left 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.

On to step 10:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 17840.6428
If we take 336 away from 360, we end up with 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 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 17840.64285
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.

Going ahead to step 12:
42 can be fit into 300 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 17840.642857
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.

Moving on to step 13:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 17840.6428571
Subtracting 42 from 60 leaves us 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.

Moving on to step 14:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 17840.64285714
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.

The final result is 17840.64285714 with a remainder of 1.2e-08.
