We look at the division of 320369 by 89 
Let's see how many times 89 fits into 320369.

Moving on to step 1:
If we divide 3 by 89, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 89

On to step 2:
89 can be fit into 32 0 times, resulting in a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 89

On to step 3:
320 divided by 89 is 3 with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 267 away from 320, we end up with 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 89

Moving on to step 4:
89 can be fit into 533 5 times, resulting in a remainder of 88.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 445 away from 533, we end up with 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 89

Step 5:
89 goes into 886 9 times with a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 359.0
The remainder is 85 after subtracting 801 from 886.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 89

On to step 6:
When dividing 859 by 89, we get 9 with a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 3599.0
Subtracting 801 from 859 leaves us with 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 7:
580 divided by 89 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 3599.6
If we subtract 534 from 580, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
If we divide 460 by 89, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 3599.65
Deduct 445 from 460 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 89 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 3599.651
The remainder is 61 after subtracting 89 from 150.
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 10:
When dividing 610 by 89, we get 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 3599.6516
If we subtract 534 from 610, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 11:
The number 89 fits into 760 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 3599.65168
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.

On to step 12:
If we divide 480 by 89, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 3599.651685
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.

On to step 13:
350 divided by 89 is 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 3599.6516853
If we take 267 away from 350, we end up 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.

Going ahead to step 14:
89 goes into 830 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 3599.65168539
Subtract 801 from 830 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 3599.65168539, with a leftover of 2.9e-08.
