We look at the division of 378099 by 71 
We want to divide 378099 by 71.

On to step 1:
71 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 71

Advancing to step 2:
71 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Take the next digit (8) from the dividend and append it to 37, then repeat: 378 / 71

Step 3:
The number 71 fits into 378 5 times, leaving a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 355 away from 378, we end up with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 71

Step 4:
If we divide 230 by 71, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 213 from 230, we get 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 71

Moving on to step 5:
71 goes into 179 2 times with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 532.0
Deduct 142 from 179 and we're left with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 71

Step 6:
379 divided by 71 is 5 with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 5325.0
The remainder is 24 after subtracting 355 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
71 goes into 240 3 times with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 5325.3
If we take 213 away from 240, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
71 goes into 270 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 5325.33
If we take 213 away from 270, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 5325.33 with a remaining 0.057.
