We divide 166390 by 68
Let's see how many times 68 fits into 166390.

Step 1:
When dividing 1 by 68, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 68

Step 2:
68 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 68

Let's proceed to step 3:
If we divide 166 by 68, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 136 away from 166, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 68

Moving on to step 4:
68 goes into 303 4 times with a remainder of 31.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 272 from 303 to get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 68

Moving on to step 5:
68 can be fit into 319 4 times, resulting in a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 244.0
Deduct 272 from 319 and we're left with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 68

Moving on to step 6:
68 goes into 470 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 2446.0
Subtracting 408 from 470 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
When dividing 620 by 68, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 2446.9
Deduct 612 from 620 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 68, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 2446.91
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
68 goes into 120 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 2446.911
If we take 68 away from 120, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 2446.911 and a remainder of 0.0052.
