20740463 ÷ 89 
Our goal is to divide 20740463 by 89.

Step 1:
When dividing 2 by 89, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 89

Going ahead to step 2:
89 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 89

Step 3:
The number 89 fits into 207 2 times, leaving a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 178 from 207 to get 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 89

Going ahead to step 4:
89 can be fit into 294 3 times, resulting in a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 267 from 294 leaves us with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 89

Going ahead to step 5:
The number 89 fits into 270 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 233.0
Subtract 267 from 270 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 89

Advancing to step 6:
89 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 2330.0
The remainder is 34 after subtracting 0 from 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 89

Moving on to step 7:
The number 89 fits into 346 3 times, leaving a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 23303.0
Subtract 267 from 346 to get 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 89

On to step 8:
89 goes into 793 8 times with a remainder of 81.
Put 8 as the next digit of the answer. 
Result so far: 233038.0
If we subtract 712 from 793, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 9:
If we divide 810 by 89, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 233038.9
Subtracting 801 from 810 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
When dividing 90 by 89, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 233038.91
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.

Let's proceed to step 11:
The number 89 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 233038.91
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
89 can be fit into 100 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 233038.9101
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.

On to step 13:
110 divided by 89 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 233038.91011
If we subtract 89 from 110, we get 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 quotient of the division is 233038.91011, and the remainder is 2.1e-05.
