Let's divide 86963506 by 86
We want to divide 86963506 by 86.

Step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 86

On to step 2:
The number 86 fits into 86 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 86 away from 86, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 86

Let's proceed to step 3:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 86

Let's proceed to step 4:
When dividing 96 by 86, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 86 from 96 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 86

Advancing to step 5:
When dividing 103 by 86, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1011.0
Deduct 86 from 103 and we're left with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 86

On to step 6:
The number 86 fits into 175 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 10112.0
If we subtract 172 from 175, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 86

On to step 7:
When dividing 30 by 86, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 101120.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 86

Step 8:
When dividing 306 by 86, we get 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 1011203.0
If we take 258 away from 306, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1011203.5
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
86 can be fit into 500 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 1011203.55
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 1011203.55 with a remaining 0.07.
