Let's divide 81528007 by 851
Our goal is to divide 81528007 by 851.

Step 1:
When dividing 8 by 851, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 851

Moving on to step 2:
When dividing 81 by 851, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 851

Let's proceed to step 3:
The number 851 fits into 815 0 times, leaving a remainder of 815.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 815 leaves us with 815.
Include the next digit (2) from the dividend after 815, then repeat: 8152 / 851

Going ahead to step 4:
851 can be fit into 8152 9 times, resulting in a remainder of 493.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7659 from 8152 and we're left with 493.
Include the next digit (8) from the dividend after 493, then repeat: 4938 / 851

Let's proceed to step 5:
The number 851 fits into 4938 5 times, leaving a remainder of 683.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 4255 from 4938 and we're left with 683.
Grab the next digit (0) from the dividend, add it to 683, then carry on: 6830 / 851

Let's proceed to step 6:
851 goes into 6830 8 times with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 958.0
The remainder is 22 after subtracting 6808 from 6830.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 851

Moving on to step 7:
If we divide 220 by 851, we get 0 and a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 9580.0
Subtract 0 from 220 to get 220.
Fetch the next digit (7) from the dividend, attach it to 220 and continue: 2207 / 851

Advancing to step 8:
When dividing 2207 by 851, we get 2 with a remainder of 505.
Write down 2 as next digit of the result. 
Result so far: 95802.0
If we subtract 1702 from 2207, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 9:
When dividing 5050 by 851, we get 5 with a remainder of 795.
Use 5 as the next digit of our solution. 
Result so far: 95802.5
Deduct 4255 from 5050 and we're left with 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

On to step 10:
When dividing 7950 by 851, we get 9 with a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 95802.59
Subtract 7659 from 7950 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 11:
When dividing 2910 by 851, we get 3 with a remainder of 357.
The next digit of our result is 3. 
Result so far: 95802.593
If we subtract 2553 from 2910, we get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Advancing to step 12:
When dividing 3570 by 851, we get 4 with a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 95802.5934
Deduct 3404 from 3570 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 13:
851 goes into 1660 1 times with a remainder of 809.
Write down 1 as next digit of the result. 
Result so far: 95802.59341
Deduct 851 from 1660 and we're left with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

On to step 14:
851 can be fit into 8090 9 times, resulting in a remainder of 431.
Write down 9 as next digit of the result. 
Result so far: 95802.593419
The remainder is 431 after subtracting 7659 from 8090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 15:
If we divide 4310 by 851, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 95802.5934195
Subtract 4255 from 4310 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 16:
550 divided by 851 is 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 95802.5934195
Subtract 0 from 550 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

The quotient of the division is 95802.5934195, and the remainder is 5.5e-07.
