We're dividing 89123235 by 578 
We want to figure out the number of times 89123235 can be divided by 578.

Going ahead to step 1:
When dividing 8 by 578, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 578

Step 2:
578 goes into 89 0 times with 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.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 578

Advancing to step 3:
578 can be fit into 891 1 times, resulting in a remainder of 313.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 578 from 891 leaves us with 313.
Grab the next digit (2) from the dividend, add it to 313, then carry on: 3132 / 578

Moving on to step 4:
3132 divided by 578 is 5 with a remainder of 242.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 2890 away from 3132, we end up with 242.
Fetch the next digit (3) from the dividend, attach it to 242 and continue: 2423 / 578

On to step 5:
578 goes into 2423 4 times with a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we subtract 2312 from 2423, we get 111.
Bring next digit (2) of the dividend behind the 111 and repeat the process: 1112 / 578

Let's proceed to step 6:
The number 578 fits into 1112 1 times, leaving a remainder of 534.
Put 1 as the next digit of the answer. 
Result so far: 1541.0
Subtracting 578 from 1112 leaves us with 534.
Grab the next digit (3) from the dividend, add it to 534, then carry on: 5343 / 578

Going ahead to step 7:
If we divide 5343 by 578, we get 9 and a remainder of 141.
Record the quotient 9 as the next digit in the result. 
Result so far: 15419.0
If we subtract 5202 from 5343, we get 141.
Grab the next digit (5) from the dividend, add it to 141, then carry on: 1415 / 578

Let's proceed to step 8:
578 goes into 1415 2 times with a remainder of 259.
Put 2 as the next digit of the answer. 
Result so far: 154192.0
The remainder is 259 after subtracting 1156 from 1415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

On to step 9:
578 goes into 2590 4 times with a remainder of 278.
The next digit of our result is 4. 
Result so far: 154192.4
Subtract 2312 from 2590 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 10:
2780 divided by 578 is 4 with a remainder of 468.
The next digit of our result is 4. 
Result so far: 154192.44
Subtracting 2312 from 2780 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

After the division, we end up with 154192.44 and a remainder of 0.468.
