79843543 ÷ 808 
Our goal is to divide 79843543 by 808.

Moving on to step 1:
808 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 808

Advancing to step 2:
808 can be fit into 79 0 times, resulting in a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 808

Advancing to step 3:
808 goes into 798 0 times with a remainder of 798.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 798 leaves us with 798.
Append the next digit (4) from the dividend to 798 and continue with: 7984 / 808

Step 4:
7984 divided by 808 is 9 with a remainder of 712.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 712 after subtracting 7272 from 7984.
Grab the next digit (3) from the dividend, add it to 712, then carry on: 7123 / 808

On to step 5:
808 goes into 7123 8 times with a remainder of 659.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Subtract 6464 from 7123 to get 659.
Take the next digit (5) from the dividend and append it to 659, then repeat: 6595 / 808

Let's proceed to step 6:
When dividing 6595 by 808, we get 8 with a remainder of 131.
Record the quotient 8 as the next digit in the result. 
Result so far: 988.0
The remainder is 131 after subtracting 6464 from 6595.
Include the next digit (4) from the dividend after 131, then repeat: 1314 / 808

On to step 7:
808 goes into 1314 1 times with a remainder of 506.
The number 1 becomes the next digit in our result. 
Result so far: 9881.0
Deduct 808 from 1314 and we're left with 506.
Include the next digit (3) from the dividend after 506, then repeat: 5063 / 808

Advancing to step 8:
5063 divided by 808 is 6 with a remainder of 215.
Write down 6 as next digit of the result. 
Result so far: 98816.0
The remainder is 215 after subtracting 4848 from 5063.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 9:
808 can be fit into 2150 2 times, resulting in a remainder of 534.
Record the quotient 2 as the next digit in the result. 
Result so far: 98816.2
Subtracting 1616 from 2150 leaves us with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 10:
5340 divided by 808 is 6 with a remainder of 492.
The next digit of our result is 6. 
Result so far: 98816.26
If we take 4848 away from 5340, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 11:
The number 808 fits into 4920 6 times, leaving a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 98816.266
If we subtract 4848 from 4920, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 98816.266, with a leftover of 0.0072.
