We're dividing 167669 by 42 
Let's see how many times 42 fits into 167669.

Let's proceed to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 42

Advancing to step 2:
When dividing 16 by 42, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 42

On to step 3:
167 divided by 42 is 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 126 away from 167, we end up with 41.
Append the next digit (6) from the dividend to 41 and continue with: 416 / 42

Let's proceed to step 4:
416 divided by 42 is 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 378 from 416, we get 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 42

Going ahead to step 5:
When dividing 386 by 42, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 399.0
The remainder is 8 after subtracting 378 from 386.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 42

On to step 6:
The number 42 fits into 89 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 3992.0
Deduct 84 from 89 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 42 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 3992.1
If we subtract 42 from 50, 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.

Moving on to step 8:
When dividing 80 by 42, we get 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 3992.11
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.

The final result is 3992.11 with a remainder of 0.038.
