81523030 divided by 851 
We want to figure out the number of times 81523030 can be divided by 851.

Step 1:
The number 851 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 851

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
If we take 0 away from 81, we end up with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 851

Step 3:
851 can be fit into 815 0 times, resulting in 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.
Grab the next digit (2) from the dividend, add it to 815, then carry on: 8152 / 851

On to step 4:
The number 851 fits into 8152 9 times, leaving a remainder of 493.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7659 away from 8152, we end up with 493.
Fetch the next digit (3) from the dividend, attach it to 493 and continue: 4933 / 851

Moving on to step 5:
If we divide 4933 by 851, we get 5 and a remainder of 678.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtract 4255 from 4933 to get 678.
Append the next digit (0) from the dividend to 678 and continue with: 6780 / 851

Moving on to step 6:
If we divide 6780 by 851, we get 7 and a remainder of 823.
Write down 7 as next digit of the result. 
Result so far: 957.0
The remainder is 823 after subtracting 5957 from 6780.
Include the next digit (3) from the dividend after 823, then repeat: 8233 / 851

Advancing to step 7:
When dividing 8233 by 851, we get 9 with a remainder of 574.
Write down 9 as next digit of the result. 
Result so far: 9579.0
Subtracting 7659 from 8233 leaves us with 574.
Append the next digit (0) from the dividend to 574 and continue with: 5740 / 851

Step 8:
The number 851 fits into 5740 6 times, leaving a remainder of 634.
The next digit of our result is 6. 
Result so far: 95796.0
If we subtract 5106 from 5740, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Advancing to step 9:
851 goes into 6340 7 times with a remainder of 383.
Put 7 as the next digit of the answer. 
Result so far: 95796.7
If we take 5957 away from 6340, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Let's proceed to step 10:
When dividing 3830 by 851, we get 4 with a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 95796.74
If we take 3404 away from 3830, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 11:
The number 851 fits into 4260 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 95796.745
If we take 4255 away from 4260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
50 divided by 851 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 95796.745
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
851 can be fit into 500 0 times, resulting in a remainder of 500.
The next digit of our result is 0. 
Result so far: 95796.745
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 95796.745 with a balance of 0.0005.
