75145889 ÷ 665 
We want to divide 75145889 by 665.

Moving on to step 1:
When dividing 7 by 665, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 665

Moving on to step 2:
75 divided by 665 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 665

On to step 3:
The number 665 fits into 751 1 times, leaving a remainder of 86.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 665 from 751 to get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 665

Moving on to step 4:
The number 665 fits into 864 1 times, leaving a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 665 from 864, we get 199.
Bring next digit (5) of the dividend behind the 199 and repeat the process: 1995 / 665

Let's proceed to step 5:
The number 665 fits into 1995 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
Subtract 1995 from 1995 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 665

On to step 6:
665 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 1130.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 665

Going ahead to step 7:
If we divide 88 by 665, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 11300.0
Subtract 0 from 88 to get 88.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 665

Moving on to step 8:
The number 665 fits into 889 1 times, leaving a remainder of 224.
The next digit of our result is 1. 
Result so far: 113001.0
The remainder is 224 after subtracting 665 from 889.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 9:
If we divide 2240 by 665, we get 3 and a remainder of 245.
The next digit of our result is 3. 
Result so far: 113001.3
The remainder is 245 after subtracting 1995 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 10:
2450 divided by 665 is 3 with a remainder of 455.
Put 3 as the next digit of the answer. 
Result so far: 113001.33
Deduct 1995 from 2450 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

After the division, we end up with 113001.33 and a remainder of 0.455.
