We're dividing 978891 by 89 
We're looking to find how many times 89 goes into 978891.

On to step 1:
89 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 89

Going ahead to step 2:
89 goes into 97 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 89 from 97 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 89

Going ahead to step 3:
When dividing 88 by 89, we get 0 with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 88, we end up with 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 89

Going ahead to step 4:
89 can be fit into 888 9 times, resulting in a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we take 801 away from 888, we end up with 87.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 89

Going ahead to step 5:
89 can be fit into 879 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 1099.0
Subtract 801 from 879 to get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 89

Advancing to step 6:
89 can be fit into 781 8 times, resulting in a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 10998.0
If we take 712 away from 781, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
The number 89 fits into 690 7 times, leaving a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 10998.7
If we take 623 away from 690, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 8:
If we divide 670 by 89, we get 7 and a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 10998.77
Deduct 623 from 670 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 10998.77 with a remaining 0.047.
