690128 divided by 42 
We want to figure out the number of times 690128 can be divided by 42.

On to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 42

Moving on to step 2:
42 can be fit into 69 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 42 from 69 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 42

Going ahead to step 3:
270 divided by 42 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 252 from 270 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 42

Moving on to step 4:
When dividing 181 by 42, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 164.0
If we take 168 away from 181, we end up with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 42

Step 5:
When dividing 132 by 42, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 1643.0
If we take 126 away from 132, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 42

On to step 6:
The number 42 fits into 68 1 times, leaving a remainder of 26.
The next digit of our result is 1. 
Result so far: 16431.0
If we subtract 42 from 68, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
42 goes into 260 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 16431.6
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
If we divide 80 by 42, we get 1 and a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 16431.61
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
42 goes into 380 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 16431.619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
42 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 16431.619
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 16431.61904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
42 can be fit into 320 7 times, resulting in a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 16431.619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
260 divided by 42 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 16431.6190476
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
80 divided by 42 is 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 16431.61904761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 16431.61904761 with a remainder of 3.8e-08.
