We look at the division of 86364707 by 813 
We want to divide 86364707 by 813.

Step 1:
When dividing 8 by 813, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 813

Step 2:
When dividing 86 by 813, we get 0 with 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.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 813

Going ahead to step 3:
813 goes into 863 1 times with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 813 from 863 to get 50.
Append the next digit (6) from the dividend to 50 and continue with: 506 / 813

Going ahead to step 4:
813 can be fit into 506 0 times, resulting in a remainder of 506.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 506 and we're left with 506.
Grab the next digit (4) from the dividend, add it to 506, then carry on: 5064 / 813

Let's proceed to step 5:
5064 divided by 813 is 6 with a remainder of 186.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 4878 from 5064 and we're left with 186.
Append the next digit (7) from the dividend to 186 and continue with: 1867 / 813

Step 6:
If we divide 1867 by 813, we get 2 and a remainder of 241.
The next digit of our result is 2. 
Result so far: 1062.0
The remainder is 241 after subtracting 1626 from 1867.
Bring next digit (0) of the dividend behind the 241 and repeat the process: 2410 / 813

Let's proceed to step 7:
2410 divided by 813 is 2 with a remainder of 784.
Record the quotient 2 as the next digit in the result. 
Result so far: 10622.0
If we take 1626 away from 2410, we end up with 784.
Fetch the next digit (7) from the dividend, attach it to 784 and continue: 7847 / 813

On to step 8:
The number 813 fits into 7847 9 times, leaving a remainder of 530.
Put 9 as the next digit of the answer. 
Result so far: 106229.0
If we subtract 7317 from 7847, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 9:
If we divide 5300 by 813, we get 6 and a remainder of 422.
Put 6 as the next digit of the answer. 
Result so far: 106229.6
If we subtract 4878 from 5300, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 10:
4220 divided by 813 is 5 with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 106229.65
If we take 4065 away from 4220, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 11:
When dividing 1550 by 813, we get 1 with a remainder of 737.
Write down 1 as next digit of the result. 
Result so far: 106229.651
Subtracting 813 from 1550 leaves us with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

On to step 12:
The number 813 fits into 7370 9 times, leaving a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 106229.6519
Deduct 7317 from 7370 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 13:
The number 813 fits into 530 0 times, leaving a remainder of 530.
Record the quotient 0 as the next digit in the result. 
Result so far: 106229.6519
Subtracting 0 from 530 leaves us with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 14:
5300 divided by 813 is 6 with a remainder of 422.
Use 6 as the next digit of our solution. 
Result so far: 106229.651906
The remainder is 422 after subtracting 4878 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 15:
If we divide 4220 by 813, we get 5 and a remainder of 155.
The next digit of our result is 5. 
Result so far: 106229.6519065
If we take 4065 away from 4220, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 16:
1550 divided by 813 is 1 with a remainder of 737.
The next digit of our result is 1. 
Result so far: 106229.65190651
If we subtract 813 from 1550, we get 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

The final result is 106229.65190651 with a remainder of 7.37e-07.
