87249315 ÷ 806 
We want to divide 87249315 by 806.

On to step 1:
806 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 806

Advancing to step 2:
806 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 806

Moving on to step 3:
The number 806 fits into 872 1 times, leaving a remainder of 66.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 66 after subtracting 806 from 872.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 806

Step 4:
The number 806 fits into 664 0 times, leaving a remainder of 664.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 664 to get 664.
Bring next digit (9) of the dividend behind the 664 and repeat the process: 6649 / 806

Let's proceed to step 5:
When dividing 6649 by 806, we get 8 with a remainder of 201.
The next digit of our result is 8. 
Result so far: 108.0
Subtract 6448 from 6649 to get 201.
Include the next digit (3) from the dividend after 201, then repeat: 2013 / 806

Moving on to step 6:
If we divide 2013 by 806, we get 2 and a remainder of 401.
The next digit of our result is 2. 
Result so far: 1082.0
If we take 1612 away from 2013, we end up with 401.
Append the next digit (1) from the dividend to 401 and continue with: 4011 / 806

Moving on to step 7:
The number 806 fits into 4011 4 times, leaving a remainder of 787.
Record the quotient 4 as the next digit in the result. 
Result so far: 10824.0
Deduct 3224 from 4011 and we're left with 787.
Fetch the next digit (5) from the dividend, attach it to 787 and continue: 7875 / 806

On to step 8:
The number 806 fits into 7875 9 times, leaving a remainder of 621.
Put 9 as the next digit of the answer. 
Result so far: 108249.0
Deduct 7254 from 7875 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Advancing to step 9:
6210 divided by 806 is 7 with a remainder of 568.
Record the quotient 7 as the next digit in the result. 
Result so far: 108249.7
The remainder is 568 after subtracting 5642 from 6210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 10:
When dividing 5680 by 806, we get 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 108249.77
If we take 5642 away from 5680, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 108249.77, with a leftover of 0.038.
