89646225 divided by 309 
Our goal is to divide 89646225 by 309.

Advancing to step 1:
309 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 309

On to step 2:
If we divide 89 by 309, we get 0 and a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Fetch the next digit (6) from the dividend, attach it to 89 and continue: 896 / 309

On to step 3:
896 divided by 309 is 2 with a remainder of 278.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 618 from 896, we get 278.
Append the next digit (4) from the dividend to 278 and continue with: 2784 / 309

Advancing to step 4:
The number 309 fits into 2784 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 2781 from 2784, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 309

On to step 5:
309 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
The remainder is 36 after subtracting 0 from 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 309

Step 6:
309 goes into 362 1 times with a remainder of 53.
The next digit of our result is 1. 
Result so far: 2901.0
Subtracting 309 from 362 leaves us with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 309

Moving on to step 7:
309 goes into 532 1 times with a remainder of 223.
Write down 1 as next digit of the result. 
Result so far: 29011.0
If we take 309 away from 532, we end up with 223.
Include the next digit (5) from the dividend after 223, then repeat: 2235 / 309

Let's proceed to step 8:
309 can be fit into 2235 7 times, resulting in a remainder of 72.
Use 7 as the next digit of our solution. 
Result so far: 290117.0
If we take 2163 away from 2235, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
When dividing 720 by 309, we get 2 with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 290117.2
If we subtract 618 from 720, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
309 goes into 1020 3 times with a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 290117.23
If we take 927 away from 1020, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 11:
When dividing 930 by 309, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 290117.233
If we take 927 away from 930, we end up 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.

The final result is 290117.233 with a remainder of 0.0003.
