672939 ÷ 42 
We're looking to find how many times 42 goes into 672939.

Moving on to step 1:
6 divided by 42 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 42

Moving on to step 2:
67 divided by 42 is 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 42 from 67 and we're left with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 42

Going ahead to step 3:
252 divided by 42 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 252 from 252, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 42

Moving on to step 4:
42 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 160.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 42

Moving on to step 5:
When dividing 93 by 42, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 1602.0
If we take 84 away from 93, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 42

Advancing to step 6:
42 goes into 99 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 16022.0
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:
42 can be fit into 150 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 16022.3
Deduct 126 from 150 and we're left 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.

On to step 8:
42 goes into 240 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 16022.35
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.

Advancing to step 9:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 16022.357
If we subtract 294 from 300, we 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.

Moving on to step 10:
42 goes into 60 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 16022.3571
Subtract 42 from 60 to 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.

Let's proceed to step 11:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 16022.35714
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.

Step 12:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 16022.357142
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.

Going ahead to step 13:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 16022.3571428
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.

Moving on to step 14:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 16022.35714285
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.

After the division, we end up with 16022.35714285 and a remainder of 3e-08.
