We're dividing 690871 by 42 
Let's see how many times 42 fits into 690871.

Advancing to step 1:
42 can be fit into 6 0 times, resulting in 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.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 42

Going ahead to step 2:
42 goes into 69 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 42 from 69 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 42

Moving on to step 3:
42 can be fit into 270 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 252 away from 270, we end up with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 42

Moving on to step 4:
When dividing 188 by 42, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 168 from 188, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 42

Step 5:
When dividing 207 by 42, we get 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 1644.0
If we take 168 away from 207, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 42

Let's proceed to step 6:
391 divided by 42 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 16449.0
Subtracting 378 from 391 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 42, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 16449.3
Deduct 126 from 130 and we're left 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 8:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 16449.3
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 16449.309
The remainder is 22 after subtracting 378 from 400.
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 10:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 16449.3095
If we take 210 away from 220, we end up with 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 11:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 16449.30952
Deduct 84 from 100 and we're left with 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 12:
If we divide 160 by 42, we get 3 and a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 16449.309523
Subtracting 126 from 160 leaves us 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 13:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 16449.3095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 16449.3095238
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 16449.3095238, with a leftover of 4e-08.
