We divide 71570728 by 809
We're looking to find how many times 809 goes into 71570728.

Going ahead to step 1:
7 divided by 809 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 809

Advancing to step 2:
809 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 809

Moving on to step 3:
809 can be fit into 715 0 times, resulting in a remainder of 715.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 715, we end up with 715.
Grab the next digit (7) from the dividend, add it to 715, then carry on: 7157 / 809

Step 4:
If we divide 7157 by 809, we get 8 and a remainder of 685.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 6472 away from 7157, we end up with 685.
Fetch the next digit (0) from the dividend, attach it to 685 and continue: 6850 / 809

On to step 5:
If we divide 6850 by 809, we get 8 and a remainder of 378.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 6472 from 6850 to get 378.
Fetch the next digit (7) from the dividend, attach it to 378 and continue: 3787 / 809

Moving on to step 6:
3787 divided by 809 is 4 with a remainder of 551.
Write down 4 as next digit of the result. 
Result so far: 884.0
The remainder is 551 after subtracting 3236 from 3787.
Append the next digit (2) from the dividend to 551 and continue with: 5512 / 809

On to step 7:
809 goes into 5512 6 times with a remainder of 658.
Put 6 as the next digit of the answer. 
Result so far: 8846.0
The remainder is 658 after subtracting 4854 from 5512.
Include the next digit (8) from the dividend after 658, then repeat: 6588 / 809

On to step 8:
6588 divided by 809 is 8 with a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 88468.0
If we take 6472 away from 6588, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 9:
The number 809 fits into 1160 1 times, leaving a remainder of 351.
Use 1 as the next digit of our solution. 
Result so far: 88468.1
Subtracting 809 from 1160 leaves us with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 10:
809 can be fit into 3510 4 times, resulting in a remainder of 274.
The next digit of our result is 4. 
Result so far: 88468.14
The remainder is 274 after subtracting 3236 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 11:
2740 divided by 809 is 3 with a remainder of 313.
The number 3 becomes the next digit in our result. 
Result so far: 88468.143
Subtracting 2427 from 2740 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 12:
The number 809 fits into 3130 3 times, leaving a remainder of 703.
The next digit of our result is 3. 
Result so far: 88468.1433
Subtracting 2427 from 3130 leaves us with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

The final outcome is 88468.1433, with a leftover of 0.00703.
