Let's divide 85866365 by 813
Let's see how many times 813 fits into 85866365.

Let's proceed to step 1:
813 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 813

Step 2:
If we divide 85 by 813, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 813

Advancing to step 3:
813 can be fit into 858 1 times, resulting in a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 813 from 858, we get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 813

Moving on to step 4:
If we divide 456 by 813, we get 0 and a remainder of 456.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 456, we get 456.
Take the next digit (6) from the dividend and append it to 456, then repeat: 4566 / 813

On to step 5:
4566 divided by 813 is 5 with a remainder of 501.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we subtract 4065 from 4566, we get 501.
Bring next digit (3) of the dividend behind the 501 and repeat the process: 5013 / 813

Moving on to step 6:
813 can be fit into 5013 6 times, resulting in a remainder of 135.
The number 6 becomes the next digit in our result. 
Result so far: 1056.0
If we subtract 4878 from 5013, we get 135.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 813

Step 7:
When dividing 1356 by 813, we get 1 with a remainder of 543.
Put 1 as the next digit of the answer. 
Result so far: 10561.0
If we take 813 away from 1356, we end up with 543.
Append the next digit (5) from the dividend to 543 and continue with: 5435 / 813

On to step 8:
813 can be fit into 5435 6 times, resulting in a remainder of 557.
Write down 6 as next digit of the result. 
Result so far: 105616.0
Subtracting 4878 from 5435 leaves us with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Going ahead to step 9:
813 goes into 5570 6 times with a remainder of 692.
The number 6 becomes the next digit in our result. 
Result so far: 105616.6
Deduct 4878 from 5570 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Advancing to step 10:
The number 813 fits into 6920 8 times, leaving a remainder of 416.
The number 8 becomes the next digit in our result. 
Result so far: 105616.68
If we subtract 6504 from 6920, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 11:
813 can be fit into 4160 5 times, resulting in a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 105616.685
Deduct 4065 from 4160 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 12:
The number 813 fits into 950 1 times, leaving a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 105616.6851
If we subtract 813 from 950, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 13:
If we divide 1370 by 813, we get 1 and a remainder of 557.
Record the quotient 1 as the next digit in the result. 
Result so far: 105616.68511
The remainder is 557 after subtracting 813 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

The final result is 105616.68511 with a remainder of 0.000557.
