86202234 ÷ 989 
We want to divide 86202234 by 989.

Going ahead to step 1:
If we divide 8 by 989, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 989

On to step 2:
989 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (2) from the dividend, add it to 86, then carry on: 862 / 989

Moving on to step 3:
The number 989 fits into 862 0 times, leaving a remainder of 862.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 862, we end up with 862.
Append the next digit (0) from the dividend to 862 and continue with: 8620 / 989

On to step 4:
The number 989 fits into 8620 8 times, leaving a remainder of 708.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7912 from 8620 and we're left with 708.
Fetch the next digit (2) from the dividend, attach it to 708 and continue: 7082 / 989

On to step 5:
989 goes into 7082 7 times with a remainder of 159.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 6923 from 7082 leaves us with 159.
Append the next digit (2) from the dividend to 159 and continue with: 1592 / 989

On to step 6:
If we divide 1592 by 989, we get 1 and a remainder of 603.
The next digit of our result is 1. 
Result so far: 871.0
Subtract 989 from 1592 to get 603.
Take the next digit (3) from the dividend and append it to 603, then repeat: 6033 / 989

Step 7:
When dividing 6033 by 989, we get 6 with a remainder of 99.
Write down 6 as next digit of the result. 
Result so far: 8716.0
If we subtract 5934 from 6033, we get 99.
Take the next digit (4) from the dividend and append it to 99, then repeat: 994 / 989

On to step 8:
989 can be fit into 994 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 87161.0
Subtract 989 from 994 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
989 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 87161.0
If we subtract 0 from 50, we 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.

Step 10:
989 goes into 500 0 times with a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 87161.0
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 87161.0 with a remainder of 0.5.
