We look at the division of 90977529 by 489 
Our goal is to divide 90977529 by 489.

Going ahead to step 1:
489 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 489

On to step 2:
When dividing 90 by 489, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 489

Going ahead to step 3:
If we divide 909 by 489, we get 1 and a remainder of 420.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 489 from 909 and we're left with 420.
Grab the next digit (7) from the dividend, add it to 420, then carry on: 4207 / 489

Going ahead to step 4:
489 can be fit into 4207 8 times, resulting in a remainder of 295.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 3912 from 4207 and we're left with 295.
Include the next digit (7) from the dividend after 295, then repeat: 2957 / 489

Going ahead to step 5:
2957 divided by 489 is 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 186.0
If we take 2934 away from 2957, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 489

Advancing to step 6:
489 goes into 235 0 times with a remainder of 235.
Use 0 as the next digit of our solution. 
Result so far: 1860.0
Subtracting 0 from 235 leaves us with 235.
Fetch the next digit (2) from the dividend, attach it to 235 and continue: 2352 / 489

Let's proceed to step 7:
2352 divided by 489 is 4 with a remainder of 396.
The next digit of our result is 4. 
Result so far: 18604.0
If we take 1956 away from 2352, we end up with 396.
Fetch the next digit (9) from the dividend, attach it to 396 and continue: 3969 / 489

Advancing to step 8:
489 can be fit into 3969 8 times, resulting in a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 186048.0
Deduct 3912 from 3969 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 9:
When dividing 570 by 489, we get 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 186048.1
If we take 489 away from 570, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 10:
489 can be fit into 810 1 times, resulting in a remainder of 321.
Record the quotient 1 as the next digit in the result. 
Result so far: 186048.11
Deduct 489 from 810 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Our division results in 186048.11 with a remaining 0.321.
