We're dividing 43371070 by 817 
We want to divide 43371070 by 817.

Going ahead to step 1:
4 divided by 817 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 817

Let's proceed to step 2:
When dividing 43 by 817, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 817

Going ahead to step 3:
If we divide 433 by 817, we get 0 and a remainder of 433.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 433 leaves us with 433.
Take the next digit (7) from the dividend and append it to 433, then repeat: 4337 / 817

Let's proceed to step 4:
4337 divided by 817 is 5 with a remainder of 252.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 4085 from 4337 to get 252.
Append the next digit (1) from the dividend to 252 and continue with: 2521 / 817

Let's proceed to step 5:
817 goes into 2521 3 times with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 2451 from 2521 leaves us with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 817

On to step 6:
When dividing 700 by 817, we get 0 with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 530.0
The remainder is 700 after subtracting 0 from 700.
Take the next digit (7) from the dividend and append it to 700, then repeat: 7007 / 817

On to step 7:
The number 817 fits into 7007 8 times, leaving a remainder of 471.
Use 8 as the next digit of our solution. 
Result so far: 5308.0
Deduct 6536 from 7007 and we're left with 471.
Grab the next digit (0) from the dividend, add it to 471, then carry on: 4710 / 817

Moving on to step 8:
The number 817 fits into 4710 5 times, leaving a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 53085.0
The remainder is 625 after subtracting 4085 from 4710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 9:
When dividing 6250 by 817, we get 7 with a remainder of 531.
Write down 7 as next digit of the result. 
Result so far: 53085.7
Subtracting 5719 from 6250 leaves us with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 10:
817 can be fit into 5310 6 times, resulting in a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 53085.76
Subtract 4902 from 5310 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 11:
The number 817 fits into 4080 4 times, leaving a remainder of 812.
Write down 4 as next digit of the result. 
Result so far: 53085.764
Deduct 3268 from 4080 and we're left with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Step 12:
When dividing 8120 by 817, we get 9 with a remainder of 767.
Write down 9 as next digit of the result. 
Result so far: 53085.7649
Subtract 7353 from 8120 to get 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Advancing to step 13:
If we divide 7670 by 817, we get 9 and a remainder of 317.
The next digit of our result is 9. 
Result so far: 53085.76499
If we take 7353 away from 7670, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final result is 53085.76499 with a remainder of 0.000317.
