Let's divide 91821000 by 511
We want to figure out the number of times 91821000 can be divided by 511.

Going ahead to step 1:
511 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 511

Step 2:
If we divide 91 by 511, we get 0 and a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 511

Step 3:
The number 511 fits into 918 1 times, leaving a remainder of 407.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 407 after subtracting 511 from 918.
Take the next digit (2) from the dividend and append it to 407, then repeat: 4072 / 511

Step 4:
511 goes into 4072 7 times with a remainder of 495.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 3577 away from 4072, we end up with 495.
Append the next digit (1) from the dividend to 495 and continue with: 4951 / 511

Moving on to step 5:
511 can be fit into 4951 9 times, resulting in a remainder of 352.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Subtract 4599 from 4951 to get 352.
Bring next digit (0) of the dividend behind the 352 and repeat the process: 3520 / 511

On to step 6:
3520 divided by 511 is 6 with a remainder of 454.
Put 6 as the next digit of the answer. 
Result so far: 1796.0
Subtracting 3066 from 3520 leaves us with 454.
Append the next digit (0) from the dividend to 454 and continue with: 4540 / 511

Going ahead to step 7:
The number 511 fits into 4540 8 times, leaving a remainder of 452.
Write down 8 as next digit of the result. 
Result so far: 17968.0
If we subtract 4088 from 4540, we get 452.
Bring next digit (0) of the dividend behind the 452 and repeat the process: 4520 / 511

Moving on to step 8:
When dividing 4520 by 511, we get 8 with a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 179688.0
If we take 4088 away from 4520, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 9:
511 can be fit into 4320 8 times, resulting in a remainder of 232.
Record the quotient 8 as the next digit in the result. 
Result so far: 179688.8
If we take 4088 away from 4320, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 10:
511 can be fit into 2320 4 times, resulting in a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 179688.84
The remainder is 276 after subtracting 2044 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
When dividing 2760 by 511, we get 5 with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 179688.845
If we subtract 2555 from 2760, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 12:
511 goes into 2050 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 179688.8454
If we subtract 2044 from 2050, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
511 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 179688.8454
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
If we divide 600 by 511, we get 1 and a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 179688.845401
Deduct 511 from 600 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 15:
If we divide 890 by 511, we get 1 and a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 179688.8454011
Subtract 511 from 890 to get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

The quotient of the division is 179688.8454011, and the remainder is 3.79e-06.
