We look at the division of 81587539 by 955 
Our goal is to divide 81587539 by 955.

On to step 1:
955 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 955

Advancing to step 2:
955 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 955

Going ahead to step 3:
955 can be fit into 815 0 times, resulting in a remainder of 815.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 815 to get 815.
Take the next digit (8) from the dividend and append it to 815, then repeat: 8158 / 955

Moving on to step 4:
955 can be fit into 8158 8 times, resulting in a remainder of 518.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 518 after subtracting 7640 from 8158.
Append the next digit (7) from the dividend to 518 and continue with: 5187 / 955

Advancing to step 5:
When dividing 5187 by 955, we get 5 with a remainder of 412.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 4775 from 5187, we get 412.
Take the next digit (5) from the dividend and append it to 412, then repeat: 4125 / 955

Moving on to step 6:
When dividing 4125 by 955, we get 4 with a remainder of 305.
Write down 4 as next digit of the result. 
Result so far: 854.0
If we subtract 3820 from 4125, we get 305.
Bring next digit (3) of the dividend behind the 305 and repeat the process: 3053 / 955

On to step 7:
955 goes into 3053 3 times with a remainder of 188.
The number 3 becomes the next digit in our result. 
Result so far: 8543.0
Deduct 2865 from 3053 and we're left with 188.
Take the next digit (9) from the dividend and append it to 188, then repeat: 1889 / 955

Step 8:
1889 divided by 955 is 1 with a remainder of 934.
Write down 1 as next digit of the result. 
Result so far: 85431.0
Deduct 955 from 1889 and we're left with 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Step 9:
955 goes into 9340 9 times with a remainder of 745.
Record the quotient 9 as the next digit in the result. 
Result so far: 85431.9
The remainder is 745 after subtracting 8595 from 9340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

On to step 10:
955 can be fit into 7450 7 times, resulting in a remainder of 765.
Record the quotient 7 as the next digit in the result. 
Result so far: 85431.97
Subtracting 6685 from 7450 leaves us with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Advancing to step 11:
The number 955 fits into 7650 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 85431.978
Deduct 7640 from 7650 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 955, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 85431.978
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
The number 955 fits into 1000 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 85431.97801
Deduct 955 from 1000 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 14:
The number 955 fits into 450 0 times, leaving a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 85431.97801
Deduct 0 from 450 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 15:
If we divide 4500 by 955, we get 4 and a remainder of 680.
The number 4 becomes the next digit in our result. 
Result so far: 85431.9780104
The remainder is 680 after subtracting 3820 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 16:
6800 divided by 955 is 7 with a remainder of 115.
Record the quotient 7 as the next digit in the result. 
Result so far: 85431.97801047
If we subtract 6685 from 6800, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

After the division, we end up with 85431.97801047 and a remainder of 1.15e-07.
