Let's divide 166421 by 67
Let's see how many times 67 fits into 166421.

Going ahead to step 1:
If we divide 1 by 67, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 67

On to step 2:
16 divided by 67 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 67

Step 3:
166 divided by 67 is 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 134 from 166 and we're left with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 67

Going ahead to step 4:
If we divide 324 by 67, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 268 from 324 leaves us with 56.
Append the next digit (2) from the dividend to 56 and continue with: 562 / 67

Advancing to step 5:
67 goes into 562 8 times with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
Subtract 536 from 562 to get 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 67

On to step 6:
67 goes into 261 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 2483.0
Deduct 201 from 261 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 67, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 2483.8
Deduct 536 from 600 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
67 can be fit into 640 9 times, resulting in a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 2483.89
The remainder is 37 after subtracting 603 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
370 divided by 67 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 2483.895
Subtracting 335 from 370 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
If we divide 350 by 67, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2483.8955
Deduct 335 from 350 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 2483.8955 and a remainder of 0.00015.
