80597645 ÷ 595 
We're looking to find how many times 595 goes into 80597645.

Advancing to step 1:
If we divide 8 by 595, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 595

Advancing to step 2:
If we divide 80 by 595, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 595

Step 3:
When dividing 805 by 595, we get 1 with a remainder of 210.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 210 after subtracting 595 from 805.
Take the next digit (9) from the dividend and append it to 210, then repeat: 2109 / 595

On to step 4:
If we divide 2109 by 595, we get 3 and a remainder of 324.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1785 away from 2109, we end up with 324.
Bring next digit (7) of the dividend behind the 324 and repeat the process: 3247 / 595

Step 5:
595 can be fit into 3247 5 times, resulting in a remainder of 272.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Subtracting 2975 from 3247 leaves us with 272.
Fetch the next digit (6) from the dividend, attach it to 272 and continue: 2726 / 595

Moving on to step 6:
The number 595 fits into 2726 4 times, leaving a remainder of 346.
The number 4 becomes the next digit in our result. 
Result so far: 1354.0
Subtracting 2380 from 2726 leaves us with 346.
Fetch the next digit (4) from the dividend, attach it to 346 and continue: 3464 / 595

Going ahead to step 7:
595 can be fit into 3464 5 times, resulting in a remainder of 489.
Put 5 as the next digit of the answer. 
Result so far: 13545.0
Subtract 2975 from 3464 to get 489.
Include the next digit (5) from the dividend after 489, then repeat: 4895 / 595

Step 8:
The number 595 fits into 4895 8 times, leaving a remainder of 135.
The next digit of our result is 8. 
Result so far: 135458.0
Deduct 4760 from 4895 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
If we divide 1350 by 595, we get 2 and a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 135458.2
The remainder is 160 after subtracting 1190 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
When dividing 1600 by 595, we get 2 with a remainder of 410.
The next digit of our result is 2. 
Result so far: 135458.22
Subtracting 1190 from 1600 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final outcome is 135458.22, with a leftover of 0.41.
