We look at the division of 689251 by 42 
Our goal is to divide 689251 by 42.

Advancing to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 42

Step 2:
42 can be fit into 68 1 times, resulting in a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 68 and we're left with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 42

Advancing to step 3:
42 goes into 269 6 times with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 252 from 269, we get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 42

Moving on to step 4:
42 can be fit into 172 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 168 from 172 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 42

On to step 5:
42 can be fit into 45 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1641.0
Subtracting 42 from 45 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 42

Step 6:
42 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 16410.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
42 goes into 310 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 16410.7
If we take 294 away from 310, we end up 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 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 16410.73
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 16410.738
Subtract 336 from 340 to 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.

Going ahead to step 10:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 16410.738
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.

Moving on to step 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 16410.73809
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.

Advancing to step 12:
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: 16410.738095
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.

Step 13:
If we divide 100 by 42, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 16410.7380952
If we subtract 84 from 100, we 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.

Going ahead to step 14:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 16410.73809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 16410.73809523 and a remainder of 3.4e-08.
