88136697 ÷ 809 
We want to divide 88136697 by 809.

Moving on to step 1:
If we divide 8 by 809, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 809

On to step 2:
88 divided by 809 is 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 88 to get 88.
Bring next digit (1) of the dividend behind the 88 and repeat the process: 881 / 809

Moving on to step 3:
809 can be fit into 881 1 times, resulting in a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 809 from 881 leaves us with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 809

On to step 4:
If we divide 723 by 809, we get 0 and a remainder of 723.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 723, we end up with 723.
Fetch the next digit (6) from the dividend, attach it to 723 and continue: 7236 / 809

Let's proceed to step 5:
7236 divided by 809 is 8 with a remainder of 764.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 6472 from 7236 to get 764.
Fetch the next digit (6) from the dividend, attach it to 764 and continue: 7646 / 809

Moving on to step 6:
7646 divided by 809 is 9 with a remainder of 365.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
Subtract 7281 from 7646 to get 365.
Grab the next digit (9) from the dividend, add it to 365, then carry on: 3659 / 809

Moving on to step 7:
If we divide 3659 by 809, we get 4 and a remainder of 423.
The number 4 becomes the next digit in our result. 
Result so far: 10894.0
If we take 3236 away from 3659, we end up with 423.
Bring next digit (7) of the dividend behind the 423 and repeat the process: 4237 / 809

Moving on to step 8:
If we divide 4237 by 809, we get 5 and a remainder of 192.
The number 5 becomes the next digit in our result. 
Result so far: 108945.0
Subtract 4045 from 4237 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
1920 divided by 809 is 2 with a remainder of 302.
Record the quotient 2 as the next digit in the result. 
Result so far: 108945.2
The remainder is 302 after subtracting 1618 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 10:
3020 divided by 809 is 3 with a remainder of 593.
Put 3 as the next digit of the answer. 
Result so far: 108945.23
If we take 2427 away from 3020, we end up with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Going ahead to step 11:
809 can be fit into 5930 7 times, resulting in a remainder of 267.
The next digit of our result is 7. 
Result so far: 108945.237
If we subtract 5663 from 5930, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 12:
When dividing 2670 by 809, we get 3 with a remainder of 243.
Put 3 as the next digit of the answer. 
Result so far: 108945.2373
Subtracting 2427 from 2670 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 13:
809 goes into 2430 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 108945.23733
If we subtract 2427 from 2430, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 108945.23733 with a remainder of 3e-06.
