We look at the division of 186466 by 75 
We want to divide 186466 by 75.

Moving on to step 1:
The number 75 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 75

Moving on to step 2:
75 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 75

Advancing to step 3:
If we divide 186 by 75, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 150 from 186, we get 36.
Grab the next digit (4) from the dividend, add it to 36, then carry on: 364 / 75

Going ahead to step 4:
364 divided by 75 is 4 with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 300 from 364 and we're left with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 75

Advancing to step 5:
75 goes into 646 8 times with a remainder of 46.
The next digit of our result is 8. 
Result so far: 248.0
Deduct 600 from 646 and we're left with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 75

Advancing to step 6:
If we divide 466 by 75, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 2486.0
If we subtract 450 from 466, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 75, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2486.2
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.

On to step 8:
When dividing 100 by 75, we get 1 with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 2486.21
If we take 75 away from 100, 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.

Advancing to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 2486.213
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.

Moving on to step 10:
250 divided by 75 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 2486.2133
Deduct 225 from 250 and we're left 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.

The final result is 2486.2133 with a remainder of 0.00025.
