We're dividing 253603 by 89 
We want to divide 253603 by 89.

Advancing to step 1:
2 divided by 89 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 89

Moving on to step 2:
25 divided by 89 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 89

Moving on to step 3:
89 goes into 253 2 times with a remainder of 75.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 75 after subtracting 178 from 253.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 89

Moving on to step 4:
756 divided by 89 is 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 712 from 756 and we're left with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 89

Going ahead to step 5:
If we divide 440 by 89, we get 4 and a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
If we subtract 356 from 440, we get 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 89

Step 6:
843 divided by 89 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 2849.0
If we subtract 801 from 843, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
The number 89 fits into 420 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 2849.4
The remainder is 64 after subtracting 356 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
640 divided by 89 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 2849.47
If we subtract 623 from 640, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
170 divided by 89 is 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 2849.471
If we take 89 away from 170, 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.

Step 10:
When dividing 810 by 89, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 2849.4719
Subtract 801 from 810 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
90 divided by 89 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 2849.47191
Deduct 89 from 90 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
If we divide 10 by 89, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 2849.47191
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
The number 89 fits into 100 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 2849.4719101
If we subtract 89 from 100, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
The number 89 fits into 110 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 2849.47191011
Deduct 89 from 110 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 2849.47191011, with a leftover of 2.1e-08.
