We're dividing 153439 by 89 
We're looking to find how many times 89 goes into 153439.

On to step 1:
The number 89 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 89

Advancing to step 2:
89 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 89

Moving on to step 3:
89 goes into 153 1 times with a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 89 from 153 and we're left with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 89

On to step 4:
644 divided by 89 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 21 after subtracting 623 from 644.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 89

Let's proceed to step 5:
89 goes into 213 2 times with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtracting 178 from 213 leaves us with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 89

On to step 6:
The number 89 fits into 359 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 1724.0
If we subtract 356 from 359, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
89 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 1724.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
89 goes into 300 3 times with a remainder of 33.
The next digit of our result is 3. 
Result so far: 1724.03
If we subtract 267 from 300, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
89 can be fit into 330 3 times, resulting in a remainder of 63.
The next digit of our result is 3. 
Result so far: 1724.033
Deduct 267 from 330 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 1724.033 with a remainder of 0.0063.
