We're dividing 149566 by 75 
Our goal is to divide 149566 by 75.

Advancing to step 1:
When dividing 1 by 75, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 75

Moving on to step 2:
14 divided by 75 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 75

Step 3:
75 can be fit into 149 1 times, resulting in a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 75 from 149, we get 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 75

Let's proceed to step 4:
75 can be fit into 745 9 times, resulting in a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 675 from 745 and we're left with 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 75

Let's proceed to step 5:
75 goes into 706 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 199.0
If we take 675 away from 706, we end up with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 75

On to step 6:
316 divided by 75 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1994.0
Deduct 300 from 316 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 75, we get 2 and a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 1994.2
If we subtract 150 from 160, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 75, we get 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1994.21
If we subtract 75 from 100, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
75 goes into 250 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 1994.213
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 1994.2133
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 1994.2133 with a remaining 0.00025.
