Let's divide 85439 by 23
Our goal is to divide 85439 by 23.

Step 1:
8 divided by 23 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 23

Step 2:
When dividing 85 by 23, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 69 from 85, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 23

Advancing to step 3:
When dividing 164 by 23, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 161 from 164 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 23

On to step 4:
If we divide 33 by 23, we get 1 and a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 371.0
Deduct 23 from 33 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 23

Advancing to step 5:
When dividing 109 by 23, we get 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 3714.0
Subtracting 92 from 109 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 6:
23 goes into 170 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3714.7
If we subtract 161 from 170, we 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.

On to step 7:
23 goes into 90 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3714.73
Deduct 69 from 90 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.

Advancing to step 8:
If we divide 210 by 23, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3714.739
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 23, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 3714.7391
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
23 goes into 70 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3714.73913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3714.73913
Subtracting 0 from 10 leaves us 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.

On to step 12:
When dividing 100 by 23, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3714.7391304
If we subtract 92 from 100, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
23 goes into 80 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3714.73913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 3714.73913043, with a leftover of 1.1e-08.
