We look at the division of 760144 by 66 
We're looking to find how many times 66 goes into 760144.

Let's proceed to step 1:
The number 66 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 66

On to step 2:
76 divided by 66 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 66 from 76 to get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 66

Moving on to step 3:
100 divided by 66 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 66 away from 100, we end up with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 66

On to step 4:
341 divided by 66 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 330 from 341 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 66

On to step 5:
The number 66 fits into 114 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1151.0
If we subtract 66 from 114, we get 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 66

Going ahead to step 6:
The number 66 fits into 484 7 times, leaving a remainder of 22.
The number 7 becomes the next digit in our result. 
Result so far: 11517.0
Subtract 462 from 484 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 66, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 11517.3
Subtracting 198 from 220 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
66 can be fit into 220 3 times, resulting in a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 11517.33
If we subtract 198 from 220, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 11517.33, with a leftover of 0.022.
