We look at the division of 81528921 by 735 
We want to figure out the number of times 81528921 can be divided by 735.

Let's proceed to step 1:
8 divided by 735 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 735

Step 2:
When dividing 81 by 735, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 735

Let's proceed to step 3:
815 divided by 735 is 1 with a remainder of 80.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 735 from 815 and we're left with 80.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 735

Let's proceed to step 4:
735 goes into 802 1 times with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 735 away from 802, we end up with 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 735

Going ahead to step 5:
When dividing 678 by 735, we get 0 with a remainder of 678.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtract 0 from 678 to get 678.
Grab the next digit (9) from the dividend, add it to 678, then carry on: 6789 / 735

Let's proceed to step 6:
If we divide 6789 by 735, we get 9 and a remainder of 174.
The number 9 becomes the next digit in our result. 
Result so far: 1109.0
If we subtract 6615 from 6789, we get 174.
Include the next digit (2) from the dividend after 174, then repeat: 1742 / 735

Step 7:
When dividing 1742 by 735, we get 2 with a remainder of 272.
The next digit of our result is 2. 
Result so far: 11092.0
Deduct 1470 from 1742 and we're left with 272.
Bring next digit (1) of the dividend behind the 272 and repeat the process: 2721 / 735

Going ahead to step 8:
When dividing 2721 by 735, we get 3 with a remainder of 516.
Write down 3 as next digit of the result. 
Result so far: 110923.0
If we subtract 2205 from 2721, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 9:
735 goes into 5160 7 times with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 110923.7
Subtracting 5145 from 5160 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
735 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 110923.7
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
1500 divided by 735 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 110923.702
Subtract 1470 from 1500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
735 goes into 300 0 times with a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 110923.702
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 13:
735 can be fit into 3000 4 times, resulting in a remainder of 60.
The next digit of our result is 4. 
Result so far: 110923.70204
Subtracting 2940 from 3000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
The number 735 fits into 600 0 times, leaving a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 110923.70204
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 15:
When dividing 6000 by 735, we get 8 with a remainder of 120.
Use 8 as the next digit of our solution. 
Result so far: 110923.7020408
If we take 5880 away from 6000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
735 goes into 1200 1 times with a remainder of 465.
Use 1 as the next digit of our solution. 
Result so far: 110923.70204081
The remainder is 465 after subtracting 735 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

The final result is 110923.70204081 with a remainder of 4.65e-07.
