Let's divide 27512187 by 805
We want to divide 27512187 by 805.

Step 1:
805 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 805

Step 2:
27 divided by 805 is 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 805

Step 3:
When dividing 275 by 805, we get 0 with a remainder of 275.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 275 and we're left with 275.
Bring next digit (1) of the dividend behind the 275 and repeat the process: 2751 / 805

Advancing to step 4:
If we divide 2751 by 805, we get 3 and a remainder of 336.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2415 from 2751 and we're left with 336.
Grab the next digit (2) from the dividend, add it to 336, then carry on: 3362 / 805

Moving on to step 5:
The number 805 fits into 3362 4 times, leaving a remainder of 142.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 3220 away from 3362, we end up with 142.
Take the next digit (1) from the dividend and append it to 142, then repeat: 1421 / 805

Let's proceed to step 6:
805 can be fit into 1421 1 times, resulting in a remainder of 616.
The next digit of our result is 1. 
Result so far: 341.0
Deduct 805 from 1421 and we're left with 616.
Append the next digit (8) from the dividend to 616 and continue with: 6168 / 805

Moving on to step 7:
The number 805 fits into 6168 7 times, leaving a remainder of 533.
Write down 7 as next digit of the result. 
Result so far: 3417.0
Subtracting 5635 from 6168 leaves us with 533.
Bring next digit (7) of the dividend behind the 533 and repeat the process: 5337 / 805

Step 8:
805 can be fit into 5337 6 times, resulting in a remainder of 507.
The number 6 becomes the next digit in our result. 
Result so far: 34176.0
Subtract 4830 from 5337 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 9:
805 can be fit into 5070 6 times, resulting in a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 34176.6
If we subtract 4830 from 5070, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
805 can be fit into 2400 2 times, resulting in a remainder of 790.
Use 2 as the next digit of our solution. 
Result so far: 34176.62
Deduct 1610 from 2400 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 11:
If we divide 7900 by 805, we get 9 and a remainder of 655.
The next digit of our result is 9. 
Result so far: 34176.629
If we take 7245 away from 7900, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

On to step 12:
When dividing 6550 by 805, we get 8 with a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 34176.6298
If we take 6440 away from 6550, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
805 goes into 1100 1 times with a remainder of 295.
Record the quotient 1 as the next digit in the result. 
Result so far: 34176.62981
Subtract 805 from 1100 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 14:
2950 divided by 805 is 3 with a remainder of 535.
Use 3 as the next digit of our solution. 
Result so far: 34176.629813
Subtracting 2415 from 2950 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Step 15:
The number 805 fits into 5350 6 times, leaving a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 34176.6298136
If we subtract 4830 from 5350, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 16:
805 goes into 5200 6 times with a remainder of 370.
Write down 6 as next digit of the result. 
Result so far: 34176.62981366
Deduct 4830 from 5200 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 34176.62981366, with a leftover of 3.7e-07.
