189493 divided by 68 
We want to figure out the number of times 189493 can be divided by 68.

Moving on to step 1:
68 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 68

Let's proceed to step 2:
If we divide 18 by 68, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 68

Moving on to step 3:
The number 68 fits into 189 2 times, leaving a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 136 from 189 to get 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 68

Advancing to step 4:
When dividing 534 by 68, we get 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 476 from 534 to get 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 68

Moving on to step 5:
68 goes into 589 8 times with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
If we take 544 away from 589, we end up with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 68

Let's proceed to step 6:
68 goes into 453 6 times with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 2786.0
Subtract 408 from 453 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
450 divided by 68 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 2786.6
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
The number 68 fits into 420 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2786.66
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 2786.66 with a remainder of 0.012.
