6486689 ÷ 811 
We want to figure out the number of times 6486689 can be divided by 811.

Step 1:
811 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 811

Advancing to step 2:
When dividing 64 by 811, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 811

Advancing to step 3:
The number 811 fits into 648 0 times, leaving a remainder of 648.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 648 leaves us with 648.
Grab the next digit (6) from the dividend, add it to 648, then carry on: 6486 / 811

Let's proceed to step 4:
The number 811 fits into 6486 7 times, leaving a remainder of 809.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 5677 from 6486 and we're left with 809.
Include the next digit (6) from the dividend after 809, then repeat: 8096 / 811

Step 5:
If we divide 8096 by 811, we get 9 and a remainder of 797.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtracting 7299 from 8096 leaves us with 797.
Fetch the next digit (8) from the dividend, attach it to 797 and continue: 7978 / 811

On to step 6:
811 can be fit into 7978 9 times, resulting in a remainder of 679.
Use 9 as the next digit of our solution. 
Result so far: 799.0
Subtracting 7299 from 7978 leaves us with 679.
Include the next digit (9) from the dividend after 679, then repeat: 6799 / 811

On to step 7:
When dividing 6799 by 811, we get 8 with a remainder of 311.
Put 8 as the next digit of the answer. 
Result so far: 7998.0
If we take 6488 away from 6799, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 8:
The number 811 fits into 3110 3 times, leaving a remainder of 677.
Put 3 as the next digit of the answer. 
Result so far: 7998.3
If we take 2433 away from 3110, we end up with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 9:
811 can be fit into 6770 8 times, resulting in a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 7998.38
Subtracting 6488 from 6770 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 10:
When dividing 2820 by 811, we get 3 with a remainder of 387.
Record the quotient 3 as the next digit in the result. 
Result so far: 7998.383
Subtracting 2433 from 2820 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Step 11:
The number 811 fits into 3870 4 times, leaving a remainder of 626.
The next digit of our result is 4. 
Result so far: 7998.3834
Subtract 3244 from 3870 to get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 12:
If we divide 6260 by 811, we get 7 and a remainder of 583.
Use 7 as the next digit of our solution. 
Result so far: 7998.38347
Deduct 5677 from 6260 and we're left with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Going ahead to step 13:
When dividing 5830 by 811, we get 7 with a remainder of 153.
Put 7 as the next digit of the answer. 
Result so far: 7998.383477
Subtract 5677 from 5830 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

After the division, we end up with 7998.383477 and a remainder of 1.53e-05.
