Let's divide 86619897 by 811
We want to divide 86619897 by 811.

On to step 1:
The number 811 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 811

Moving on to step 2:
The number 811 fits into 86 0 times, leaving a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 811

Moving on to step 3:
When dividing 866 by 811, we get 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 811 away from 866, we end up with 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 811

Advancing to step 4:
811 can be fit into 551 0 times, resulting in a remainder of 551.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 551 and we're left with 551.
Fetch the next digit (9) from the dividend, attach it to 551 and continue: 5519 / 811

Moving on to step 5:
If we divide 5519 by 811, we get 6 and a remainder of 653.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we subtract 4866 from 5519, we get 653.
Bring next digit (8) of the dividend behind the 653 and repeat the process: 6538 / 811

Moving on to step 6:
If we divide 6538 by 811, we get 8 and a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 1068.0
If we take 6488 away from 6538, we end up with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 811

Advancing to step 7:
811 goes into 509 0 times with a remainder of 509.
The number 0 becomes the next digit in our result. 
Result so far: 10680.0
Deduct 0 from 509 and we're left with 509.
Append the next digit (7) from the dividend to 509 and continue with: 5097 / 811

Step 8:
811 can be fit into 5097 6 times, resulting in a remainder of 231.
Write down 6 as next digit of the result. 
Result so far: 106806.0
Subtract 4866 from 5097 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
When dividing 2310 by 811, we get 2 with a remainder of 688.
The number 2 becomes the next digit in our result. 
Result so far: 106806.2
Deduct 1622 from 2310 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 10:
If we divide 6880 by 811, we get 8 and a remainder of 392.
Use 8 as the next digit of our solution. 
Result so far: 106806.28
Subtracting 6488 from 6880 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
The number 811 fits into 3920 4 times, leaving a remainder of 676.
The number 4 becomes the next digit in our result. 
Result so far: 106806.284
The remainder is 676 after subtracting 3244 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 12:
The number 811 fits into 6760 8 times, leaving a remainder of 272.
The next digit of our result is 8. 
Result so far: 106806.2848
Deduct 6488 from 6760 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 13:
811 can be fit into 2720 3 times, resulting in a remainder of 287.
The next digit of our result is 3. 
Result so far: 106806.28483
Subtract 2433 from 2720 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 14:
If we divide 2870 by 811, we get 3 and a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 106806.284833
Subtract 2433 from 2870 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

The final result is 106806.284833 with a remainder of 4.37e-05.
