We look at the division of 81555594 by 515 
Let's see how many times 515 fits into 81555594.

Moving on to step 1:
8 divided by 515 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 515

Moving on to step 2:
515 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 515

Let's proceed to step 3:
515 goes into 815 1 times with a remainder of 300.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 515 from 815 and we're left with 300.
Include the next digit (5) from the dividend after 300, then repeat: 3005 / 515

Moving on to step 4:
If we divide 3005 by 515, we get 5 and a remainder of 430.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2575 away from 3005, we end up with 430.
Include the next digit (5) from the dividend after 430, then repeat: 4305 / 515

Advancing to step 5:
4305 divided by 515 is 8 with a remainder of 185.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 4120 away from 4305, we end up with 185.
Append the next digit (5) from the dividend to 185 and continue with: 1855 / 515

Step 6:
515 goes into 1855 3 times with a remainder of 310.
The next digit of our result is 3. 
Result so far: 1583.0
If we subtract 1545 from 1855, we get 310.
Include the next digit (9) from the dividend after 310, then repeat: 3109 / 515

Advancing to step 7:
When dividing 3109 by 515, we get 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 15836.0
Subtract 3090 from 3109 to get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 515

Advancing to step 8:
If we divide 194 by 515, we get 0 and a remainder of 194.
Put 0 as the next digit of the answer. 
Result so far: 158360.0
If we take 0 away from 194, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 9:
515 goes into 1940 3 times with a remainder of 395.
Record the quotient 3 as the next digit in the result. 
Result so far: 158360.3
Subtract 1545 from 1940 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 10:
3950 divided by 515 is 7 with a remainder of 345.
The number 7 becomes the next digit in our result. 
Result so far: 158360.37
Subtract 3605 from 3950 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 11:
515 can be fit into 3450 6 times, resulting in a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 158360.376
Deduct 3090 from 3450 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
515 can be fit into 3600 6 times, resulting in a remainder of 510.
Write down 6 as next digit of the result. 
Result so far: 158360.3766
If we take 3090 away from 3600, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

In conclusion, the division gives 158360.3766 with a balance of 0.0051.
