We look at the division of 86415766 by 813 
We're looking to find how many times 813 goes into 86415766.

On to step 1:
8 divided by 813 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 813

Let's proceed to step 2:
86 divided by 813 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 813

Going ahead to step 3:
813 goes into 864 1 times with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 813 from 864 and we're left with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 813

Step 4:
If we divide 511 by 813, we get 0 and a remainder of 511.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 511, we get 511.
Take the next digit (5) from the dividend and append it to 511, then repeat: 5115 / 813

Advancing to step 5:
The number 813 fits into 5115 6 times, leaving a remainder of 237.
Put 6 as the next digit of the answer. 
Result so far: 106.0
Subtracting 4878 from 5115 leaves us with 237.
Grab the next digit (7) from the dividend, add it to 237, then carry on: 2377 / 813

Moving on to step 6:
If we divide 2377 by 813, we get 2 and a remainder of 751.
Write down 2 as next digit of the result. 
Result so far: 1062.0
Deduct 1626 from 2377 and we're left with 751.
Grab the next digit (6) from the dividend, add it to 751, then carry on: 7516 / 813

Step 7:
813 can be fit into 7516 9 times, resulting in a remainder of 199.
The number 9 becomes the next digit in our result. 
Result so far: 10629.0
Subtracting 7317 from 7516 leaves us with 199.
Include the next digit (6) from the dividend after 199, then repeat: 1996 / 813

Step 8:
813 can be fit into 1996 2 times, resulting in a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 106292.0
The remainder is 370 after subtracting 1626 from 1996.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 9:
When dividing 3700 by 813, we get 4 with a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 106292.4
Subtracting 3252 from 3700 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 10:
813 goes into 4480 5 times with a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 106292.45
Subtracting 4065 from 4480 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 11:
The number 813 fits into 4150 5 times, leaving a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 106292.455
The remainder is 85 after subtracting 4065 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

In conclusion, the division gives 106292.455 with a balance of 0.0085.
