431846 ÷ 89 
We want to divide 431846 by 89.

Step 1:
If we divide 4 by 89, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 89

Let's proceed to step 2:
When dividing 43 by 89, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 89

Step 3:
89 can be fit into 431 4 times, resulting in a remainder of 75.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 356 from 431, we get 75.
Fetch the next digit (8) from the dividend, attach it to 75 and continue: 758 / 89

Advancing to step 4:
If we divide 758 by 89, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we take 712 away from 758, we end up with 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 89

On to step 5:
89 can be fit into 464 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 485.0
If we take 445 away from 464, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 89

Let's proceed to step 6:
If we divide 196 by 89, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 4852.0
Deduct 178 from 196 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
89 goes into 180 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 4852.2
The remainder is 2 after subtracting 178 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
89 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4852.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
89 can be fit into 200 2 times, resulting in a remainder of 22.
The next digit of our result is 2. 
Result so far: 4852.202
If we subtract 178 from 200, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
If we divide 220 by 89, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 4852.2022
The remainder is 42 after subtracting 178 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 4852.2022 with a remaining 0.00042.
