12001571 divided by 618 
Let's see how many times 618 fits into 12001571.

Advancing to step 1:
618 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 618

Moving on to step 2:
618 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 618

Going ahead to step 3:
618 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Append the next digit (0) from the dividend to 120 and continue with: 1200 / 618

Moving on to step 4:
If we divide 1200 by 618, we get 1 and a remainder of 582.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 618 from 1200 and we're left with 582.
Append the next digit (1) from the dividend to 582 and continue with: 5821 / 618

Advancing to step 5:
The number 618 fits into 5821 9 times, leaving a remainder of 259.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 5562 away from 5821, we end up with 259.
Bring next digit (5) of the dividend behind the 259 and repeat the process: 2595 / 618

Let's proceed to step 6:
618 can be fit into 2595 4 times, resulting in a remainder of 123.
The number 4 becomes the next digit in our result. 
Result so far: 194.0
Subtract 2472 from 2595 to get 123.
Bring next digit (7) of the dividend behind the 123 and repeat the process: 1237 / 618

Let's proceed to step 7:
618 can be fit into 1237 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1942.0
Subtracting 1236 from 1237 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 618

Advancing to step 8:
11 divided by 618 is 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 19420.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
If we divide 110 by 618, we get 0 and a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 19420.0
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
618 goes into 1100 1 times with a remainder of 482.
The next digit of our result is 1. 
Result so far: 19420.01
Subtracting 618 from 1100 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 11:
The number 618 fits into 4820 7 times, leaving a remainder of 494.
The next digit of our result is 7. 
Result so far: 19420.017
If we take 4326 away from 4820, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 12:
When dividing 4940 by 618, we get 7 with a remainder of 614.
Put 7 as the next digit of the answer. 
Result so far: 19420.0177
If we take 4326 away from 4940, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

In conclusion, the division gives 19420.0177 with a balance of 0.00614.
