We're dividing 89972620 by 489 
We're looking to find how many times 489 goes into 89972620.

Moving on to step 1:
If we divide 8 by 489, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 489

Moving on to step 2:
489 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (9) from the dividend and append it to 89, then repeat: 899 / 489

Going ahead to step 3:
When dividing 899 by 489, we get 1 with a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 410 after subtracting 489 from 899.
Grab the next digit (7) from the dividend, add it to 410, then carry on: 4107 / 489

Advancing to step 4:
489 can be fit into 4107 8 times, resulting in a remainder of 195.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3912 from 4107 and we're left with 195.
Fetch the next digit (2) from the dividend, attach it to 195 and continue: 1952 / 489

Moving on to step 5:
The number 489 fits into 1952 3 times, leaving a remainder of 485.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
The remainder is 485 after subtracting 1467 from 1952.
Take the next digit (6) from the dividend and append it to 485, then repeat: 4856 / 489

On to step 6:
4856 divided by 489 is 9 with a remainder of 455.
The next digit of our result is 9. 
Result so far: 1839.0
If we subtract 4401 from 4856, we get 455.
Fetch the next digit (2) from the dividend, attach it to 455 and continue: 4552 / 489

Step 7:
4552 divided by 489 is 9 with a remainder of 151.
The number 9 becomes the next digit in our result. 
Result so far: 18399.0
Subtract 4401 from 4552 to get 151.
Grab the next digit (0) from the dividend, add it to 151, then carry on: 1510 / 489

On to step 8:
489 goes into 1510 3 times with a remainder of 43.
The next digit of our result is 3. 
Result so far: 183993.0
If we subtract 1467 from 1510, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
The number 489 fits into 430 0 times, leaving a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 183993.0
If we subtract 0 from 430, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 10:
When dividing 4300 by 489, we get 8 with a remainder of 388.
Write down 8 as next digit of the result. 
Result so far: 183993.08
If we subtract 3912 from 4300, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
489 can be fit into 3880 7 times, resulting in a remainder of 457.
Use 7 as the next digit of our solution. 
Result so far: 183993.087
Deduct 3423 from 3880 and we're left with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 12:
489 goes into 4570 9 times with a remainder of 169.
The number 9 becomes the next digit in our result. 
Result so far: 183993.0879
If we take 4401 away from 4570, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Moving on to step 13:
When dividing 1690 by 489, we get 3 with a remainder of 223.
Put 3 as the next digit of the answer. 
Result so far: 183993.08793
Deduct 1467 from 1690 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 14:
489 can be fit into 2230 4 times, resulting in a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 183993.087934
Subtracting 1956 from 2230 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 15:
If we divide 2740 by 489, we get 5 and a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 183993.0879345
If we take 2445 away from 2740, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 16:
If we divide 2950 by 489, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 183993.08793456
Subtract 2934 from 2950 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 183993.08793456, with a leftover of 1.6e-08.
