We look at the division of 86912151 by 989 
Our goal is to divide 86912151 by 989.

Moving on to step 1:
If we divide 8 by 989, we get 0 and a remainder of 8.
The next digit of our result is 0. 
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:
If we divide 86 by 989, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 989

Step 3:
If we divide 869 by 989, we get 0 and a remainder of 869.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 869, we get 869.
Take the next digit (1) from the dividend and append it to 869, then repeat: 8691 / 989

Moving on to step 4:
The number 989 fits into 8691 8 times, leaving a remainder of 779.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7912 from 8691 leaves us with 779.
Append the next digit (2) from the dividend to 779 and continue with: 7792 / 989

Moving on to step 5:
989 can be fit into 7792 7 times, resulting in a remainder of 869.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 6923 from 7792 and we're left with 869.
Bring next digit (1) of the dividend behind the 869 and repeat the process: 8691 / 989

Let's proceed to step 6:
989 can be fit into 8691 8 times, resulting in a remainder of 779.
The number 8 becomes the next digit in our result. 
Result so far: 878.0
Deduct 7912 from 8691 and we're left with 779.
Grab the next digit (5) from the dividend, add it to 779, then carry on: 7795 / 989

Going ahead to step 7:
7795 divided by 989 is 7 with a remainder of 872.
Record the quotient 7 as the next digit in the result. 
Result so far: 8787.0
Deduct 6923 from 7795 and we're left with 872.
Include the next digit (1) from the dividend after 872, then repeat: 8721 / 989

Going ahead to step 8:
989 goes into 8721 8 times with a remainder of 809.
Put 8 as the next digit of the answer. 
Result so far: 87878.0
Subtracting 7912 from 8721 leaves us with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Let's proceed to step 9:
The number 989 fits into 8090 8 times, leaving a remainder of 178.
The number 8 becomes the next digit in our result. 
Result so far: 87878.8
If we take 7912 away from 8090, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
1780 divided by 989 is 1 with a remainder of 791.
Use 1 as the next digit of our solution. 
Result so far: 87878.81
If we take 989 away from 1780, we end up with 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Going ahead to step 11:
If we divide 7910 by 989, we get 7 and a remainder of 987.
Put 7 as the next digit of the answer. 
Result so far: 87878.817
Subtract 6923 from 7910 to get 987.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9870, and continue the process.

Let's proceed to step 12:
9870 divided by 989 is 9 with a remainder of 969.
Write down 9 as next digit of the result. 
Result so far: 87878.8179
Subtracting 8901 from 9870 leaves us with 969.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9690, and continue the process.

Going ahead to step 13:
989 goes into 9690 9 times with a remainder of 789.
The next digit of our result is 9. 
Result so far: 87878.81799
The remainder is 789 after subtracting 8901 from 9690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Our division results in 87878.81799 with a remaining 0.000789.
