169910 ÷ 89 
Our goal is to divide 169910 by 89.

Advancing to step 1:
When dividing 1 by 89, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 89

Moving on to step 2:
When dividing 16 by 89, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 89

Going ahead to step 3:
The number 89 fits into 169 1 times, leaving a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 89 away from 169, we end up with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 89

On to step 4:
If we divide 809 by 89, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 801 from 809 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 89

Let's proceed to step 5:
If we divide 81 by 89, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 190.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 89

Moving on to step 6:
The number 89 fits into 810 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 1909.0
Subtracting 801 from 810 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 89, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1909.1
Subtracting 89 from 90 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
89 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1909.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
89 can be fit into 100 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1909.101
Subtracting 89 from 100 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
110 divided by 89 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1909.1011
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 1909.1011 with a remainder of 0.00021.
