We look at the division of 89123412 by 571 
We want to figure out the number of times 89123412 can be divided by 571.

Going ahead to step 1:
The number 571 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 571

Advancing to step 2:
89 divided by 571 is 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 571

Going ahead to step 3:
891 divided by 571 is 1 with a remainder of 320.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 320 after subtracting 571 from 891.
Take the next digit (2) from the dividend and append it to 320, then repeat: 3202 / 571

Advancing to step 4:
When dividing 3202 by 571, we get 5 with a remainder of 347.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2855 from 3202 and we're left with 347.
Include the next digit (3) from the dividend after 347, then repeat: 3473 / 571

Going ahead to step 5:
571 goes into 3473 6 times with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtract 3426 from 3473 to get 47.
Fetch the next digit (4) from the dividend, attach it to 47 and continue: 474 / 571

Let's proceed to step 6:
474 divided by 571 is 0 with a remainder of 474.
Write down 0 as next digit of the result. 
Result so far: 1560.0
The remainder is 474 after subtracting 0 from 474.
Take the next digit (1) from the dividend and append it to 474, then repeat: 4741 / 571

Moving on to step 7:
The number 571 fits into 4741 8 times, leaving a remainder of 173.
Use 8 as the next digit of our solution. 
Result so far: 15608.0
The remainder is 173 after subtracting 4568 from 4741.
Fetch the next digit (2) from the dividend, attach it to 173 and continue: 1732 / 571

On to step 8:
The number 571 fits into 1732 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 156083.0
Subtracting 1713 from 1732 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
The number 571 fits into 190 0 times, leaving a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 156083.0
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
1900 divided by 571 is 3 with a remainder of 187.
The next digit of our result is 3. 
Result so far: 156083.03
If we subtract 1713 from 1900, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 11:
571 goes into 1870 3 times with a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 156083.033
Subtract 1713 from 1870 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

The final outcome is 156083.033, with a leftover of 0.0157.
