We're dividing 91889027 by 489 
We want to divide 91889027 by 489.

Advancing to step 1:
If we divide 9 by 489, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 489

Let's proceed to step 2:
489 can be fit into 91 0 times, resulting in a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 489

Step 3:
918 divided by 489 is 1 with a remainder of 429.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 489 from 918 to get 429.
Bring next digit (8) of the dividend behind the 429 and repeat the process: 4298 / 489

Going ahead to step 4:
4298 divided by 489 is 8 with a remainder of 386.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 386 after subtracting 3912 from 4298.
Grab the next digit (9) from the dividend, add it to 386, then carry on: 3869 / 489

Moving on to step 5:
3869 divided by 489 is 7 with a remainder of 446.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Subtracting 3423 from 3869 leaves us with 446.
Include the next digit (0) from the dividend after 446, then repeat: 4460 / 489

Let's proceed to step 6:
4460 divided by 489 is 9 with a remainder of 59.
The next digit of our result is 9. 
Result so far: 1879.0
The remainder is 59 after subtracting 4401 from 4460.
Grab the next digit (2) from the dividend, add it to 59, then carry on: 592 / 489

Going ahead to step 7:
When dividing 592 by 489, we get 1 with a remainder of 103.
The number 1 becomes the next digit in our result. 
Result so far: 18791.0
Subtracting 489 from 592 leaves us with 103.
Take the next digit (7) from the dividend and append it to 103, then repeat: 1037 / 489

Step 8:
If we divide 1037 by 489, we get 2 and a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 187912.0
The remainder is 59 after subtracting 978 from 1037.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
If we divide 590 by 489, we get 1 and a remainder of 101.
Record the quotient 1 as the next digit in the result. 
Result so far: 187912.1
Subtracting 489 from 590 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

On to step 10:
The number 489 fits into 1010 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 187912.12
Subtracting 978 from 1010 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
489 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 187912.12
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
489 can be fit into 3200 6 times, resulting in a remainder of 266.
Write down 6 as next digit of the result. 
Result so far: 187912.1206
If we take 2934 away from 3200, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 13:
The number 489 fits into 2660 5 times, leaving a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 187912.12065
Subtracting 2445 from 2660 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 14:
489 goes into 2150 4 times with a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 187912.120654
Subtract 1956 from 2150 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 15:
489 can be fit into 1940 3 times, resulting in a remainder of 473.
Write down 3 as next digit of the result. 
Result so far: 187912.1206543
Subtract 1467 from 1940 to get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Step 16:
489 goes into 4730 9 times with a remainder of 329.
Write down 9 as next digit of the result. 
Result so far: 187912.12065439
Subtract 4401 from 4730 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

The final outcome is 187912.12065439, with a leftover of 3.29e-07.
