86985618 ÷ 802 
Our goal is to divide 86985618 by 802.

Moving on to step 1:
When dividing 8 by 802, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 802

On to step 2:
When dividing 86 by 802, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 802

Step 3:
869 divided by 802 is 1 with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 802 away from 869, we end up with 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 802

On to step 4:
802 goes into 678 0 times with a remainder of 678.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 678, we end up with 678.
Take the next digit (5) from the dividend and append it to 678, then repeat: 6785 / 802

Moving on to step 5:
802 can be fit into 6785 8 times, resulting in a remainder of 369.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtracting 6416 from 6785 leaves us with 369.
Append the next digit (6) from the dividend to 369 and continue with: 3696 / 802

Moving on to step 6:
The number 802 fits into 3696 4 times, leaving a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 1084.0
The remainder is 488 after subtracting 3208 from 3696.
Append the next digit (1) from the dividend to 488 and continue with: 4881 / 802

On to step 7:
The number 802 fits into 4881 6 times, leaving a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 10846.0
If we take 4812 away from 4881, we end up with 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 802

Let's proceed to step 8:
If we divide 698 by 802, we get 0 and a remainder of 698.
Use 0 as the next digit of our solution. 
Result so far: 108460.0
If we take 0 away from 698, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 9:
802 goes into 6980 8 times with a remainder of 564.
Use 8 as the next digit of our solution. 
Result so far: 108460.8
The remainder is 564 after subtracting 6416 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 10:
The number 802 fits into 5640 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 108460.87
If we take 5614 away from 5640, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
When dividing 260 by 802, we get 0 with a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 108460.87
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
If we divide 2600 by 802, we get 3 and a remainder of 194.
Put 3 as the next digit of the answer. 
Result so far: 108460.8703
If we subtract 2406 from 2600, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 13:
1940 divided by 802 is 2 with a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 108460.87032
Subtract 1604 from 1940 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 14:
When dividing 3360 by 802, we get 4 with a remainder of 152.
The next digit of our result is 4. 
Result so far: 108460.870324
Deduct 3208 from 3360 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
1520 divided by 802 is 1 with a remainder of 718.
Put 1 as the next digit of the answer. 
Result so far: 108460.8703241
The remainder is 718 after subtracting 802 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 16:
When dividing 7180 by 802, we get 8 with a remainder of 764.
Put 8 as the next digit of the answer. 
Result so far: 108460.87032418
If we take 6416 away from 7180, we end up with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Our division results in 108460.87032418 with a remaining 7.64e-07.
