189450 ÷ 8 
We're looking to find how many times 8 goes into 189450.

Step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 8

Step 2:
18 divided by 8 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 16 from 18, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 8

Going ahead to step 3:
If we divide 29 by 8, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 24 from 29, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 8

Going ahead to step 4:
When dividing 54 by 8, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 236.0
The remainder is 6 after subtracting 48 from 54.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 8

Moving on to step 5:
If we divide 65 by 8, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 2368.0
If we take 64 away from 65, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 8

Step 6:
10 divided by 8 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 23681.0
Subtract 8 from 10 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 7:
20 divided by 8 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 23681.2
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 23681.25
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23681.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23681.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 23681.25 with a remainder of 0.0.
