140186 ÷ 75 
We're looking to find how many times 75 goes into 140186.

Step 1:
The number 75 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 75

Moving on to step 2:
75 can be fit into 14 0 times, resulting in a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 75

Moving on to step 3:
The number 75 fits into 140 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 75 from 140 to get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 75

Advancing to step 4:
651 divided by 75 is 8 with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 600 from 651 leaves us with 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 75

On to step 5:
When dividing 518 by 75, we get 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 186.0
Subtract 450 from 518 to get 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 75

Moving on to step 6:
686 divided by 75 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1869.0
Subtract 675 from 686 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
75 can be fit into 110 1 times, resulting in a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1869.1
Subtracting 75 from 110 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.

Advancing to step 8:
350 divided by 75 is 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 1869.14
Subtracting 300 from 350 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 75 is 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 1869.146
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
500 divided by 75 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 1869.1466
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 1869.1466, with a leftover of 0.0005.
