We're dividing 89769050 by 18 
We want to figure out the number of times 89769050 can be divided by 18.

On to step 1:
18 goes into 8 0 times 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 (9) from the dividend, attach it to 8 and continue: 89 / 18

Step 2:
18 can be fit into 89 4 times, resulting in a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 72 from 89, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 18

Step 3:
The number 18 fits into 177 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 49.0
Subtract 162 from 177 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 18

Moving on to step 4:
The number 18 fits into 156 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 498.0
If we take 144 away from 156, we end up with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 18

Advancing to step 5:
If we divide 129 by 18, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 4987.0
If we take 126 away from 129, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 18

Moving on to step 6:
18 goes into 30 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 49871.0
If we subtract 18 from 30, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 18

Let's proceed to step 7:
18 can be fit into 125 6 times, resulting in a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 498716.0
Subtracting 108 from 125 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 18

Step 8:
18 goes into 170 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 4987169.0
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4987169.4
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 18 fits into 80 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4987169.44
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 4987169.44 with a remainder of 0.008.
