878969 divided by 90 
Our goal is to divide 878969 by 90.

Advancing to step 1:
When dividing 8 by 90, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 90

Going ahead to step 2:
90 can be fit into 87 0 times, resulting in a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (8) from the dividend after 87, then repeat: 878 / 90

Going ahead to step 3:
The number 90 fits into 878 9 times, leaving a remainder of 68.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 810 from 878, we get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 90

Let's proceed to step 4:
If we divide 689 by 90, we get 7 and a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Deduct 630 from 689 and we're left with 59.
Fetch the next digit (6) from the dividend, attach it to 59 and continue: 596 / 90

Let's proceed to step 5:
The number 90 fits into 596 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 976.0
If we take 540 away from 596, we end up with 56.
Take the next digit (9) from the dividend and append it to 56, then repeat: 569 / 90

Going ahead to step 6:
If we divide 569 by 90, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 9766.0
Subtracting 540 from 569 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 90 is 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 9766.3
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 9766.32
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 9766.322
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 9766.322, with a leftover of 0.002.
