305436 ÷ 89 
Our goal is to divide 305436 by 89.

Advancing to step 1:
The number 89 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 89

Moving on to step 2:
89 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 89

Advancing to step 3:
305 divided by 89 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 267 from 305 and we're left with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 89

Let's proceed to step 4:
384 divided by 89 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 34.0
The remainder is 28 after subtracting 356 from 384.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 89

Let's proceed to step 5:
When dividing 283 by 89, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
Subtracting 267 from 283 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 89

Let's proceed to step 6:
If we divide 166 by 89, we get 1 and a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 3431.0
If we subtract 89 from 166, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
89 can be fit into 770 8 times, resulting in a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 3431.8
If we subtract 712 from 770, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
89 goes into 580 6 times with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 3431.86
If we take 534 away from 580, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
89 goes into 460 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 3431.865
The remainder is 15 after subtracting 445 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 89 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 3431.8651
If we take 89 away from 150, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 11:
The number 89 fits into 610 6 times, leaving a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 3431.86516
Deduct 534 from 610 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
The number 89 fits into 760 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 3431.865168
Deduct 712 from 760 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
89 can be fit into 480 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3431.8651685
Subtract 445 from 480 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
89 goes into 350 3 times with a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 3431.86516853
Subtracting 267 from 350 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Our division results in 3431.86516853 with a remaining 8.3e-08.
