670885 ÷ 42 
We want to divide 670885 by 42.

On to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 42

Advancing to step 2:
42 can be fit into 67 1 times, resulting in a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 42 from 67 to get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 42

Let's proceed to step 3:
250 divided by 42 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 210 from 250 to get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 42

On to step 4:
The number 42 fits into 408 9 times, leaving a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
Subtracting 378 from 408 leaves us with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 42

Advancing to step 5:
When dividing 308 by 42, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 1597.0
Deduct 294 from 308 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 42

Advancing to step 6:
42 goes into 145 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 15973.0
Subtract 126 from 145 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 42, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 15973.4
If we subtract 168 from 190, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 42 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15973.45
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
42 goes into 100 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 15973.452
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 42 fits into 160 3 times, leaving a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 15973.4523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 15973.45238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 42, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 15973.45238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
400 divided by 42 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 15973.4523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
42 goes into 220 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 15973.45238095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 15973.45238095, and the remainder is 1e-08.
