We're dividing 393703 by 71 
We're looking to find how many times 71 goes into 393703.

On to step 1:
If we divide 3 by 71, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 71

On to step 2:
If we divide 39 by 71, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 71

On to step 3:
When dividing 393 by 71, we get 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 355 from 393 and we're left with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 71

On to step 4:
The number 71 fits into 387 5 times, leaving a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtracting 355 from 387 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 71

On to step 5:
If we divide 320 by 71, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 554.0
If we take 284 away from 320, we end up with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 71

Advancing to step 6:
363 divided by 71 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5545.0
Subtract 355 from 363 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
71 goes into 80 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 5545.1
Subtracting 71 from 80 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
When dividing 90 by 71, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 5545.11
Subtracting 71 from 90 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 5545.11 and a remainder of 0.019.
