We're dividing 81543639 by 953 
Our goal is to divide 81543639 by 953.

Step 1:
If we divide 8 by 953, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 953

Let's proceed to step 2:
953 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 953

Going ahead to step 3:
953 can be fit into 815 0 times, resulting in a remainder of 815.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 815 to get 815.
Bring next digit (4) of the dividend behind the 815 and repeat the process: 8154 / 953

Let's proceed to step 4:
8154 divided by 953 is 8 with a remainder of 530.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7624 away from 8154, we end up with 530.
Append the next digit (3) from the dividend to 530 and continue with: 5303 / 953

On to step 5:
When dividing 5303 by 953, we get 5 with a remainder of 538.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 4765 from 5303 to get 538.
Bring next digit (6) of the dividend behind the 538 and repeat the process: 5386 / 953

Step 6:
The number 953 fits into 5386 5 times, leaving a remainder of 621.
Record the quotient 5 as the next digit in the result. 
Result so far: 855.0
If we subtract 4765 from 5386, we get 621.
Bring next digit (3) of the dividend behind the 621 and repeat the process: 6213 / 953

Let's proceed to step 7:
When dividing 6213 by 953, we get 6 with a remainder of 495.
The next digit of our result is 6. 
Result so far: 8556.0
The remainder is 495 after subtracting 5718 from 6213.
Bring next digit (9) of the dividend behind the 495 and repeat the process: 4959 / 953

Let's proceed to step 8:
953 can be fit into 4959 5 times, resulting in a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 85565.0
Subtract 4765 from 4959 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 9:
953 goes into 1940 2 times with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 85565.2
Deduct 1906 from 1940 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
When dividing 340 by 953, we get 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 85565.2
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
953 goes into 3400 3 times with a remainder of 541.
Use 3 as the next digit of our solution. 
Result so far: 85565.203
Subtracting 2859 from 3400 leaves us with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Going ahead to step 12:
5410 divided by 953 is 5 with a remainder of 645.
Put 5 as the next digit of the answer. 
Result so far: 85565.2035
If we take 4765 away from 5410, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Let's proceed to step 13:
If we divide 6450 by 953, we get 6 and a remainder of 732.
Put 6 as the next digit of the answer. 
Result so far: 85565.20356
If we subtract 5718 from 6450, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 14:
The number 953 fits into 7320 7 times, leaving a remainder of 649.
Put 7 as the next digit of the answer. 
Result so far: 85565.203567
Subtracting 6671 from 7320 leaves us with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Going ahead to step 15:
The number 953 fits into 6490 6 times, leaving a remainder of 772.
Put 6 as the next digit of the answer. 
Result so far: 85565.2035676
If we subtract 5718 from 6490, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 16:
The number 953 fits into 7720 8 times, leaving a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 85565.20356768
If we subtract 7624 from 7720, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 85565.20356768, with a leftover of 9.6e-08.
