19789323 ÷ 618 
Our goal is to divide 19789323 by 618.

Step 1:
The number 618 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 618

Advancing to step 2:
If we divide 19 by 618, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 618

Step 3:
The number 618 fits into 197 0 times, leaving a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Fetch the next digit (8) from the dividend, attach it to 197 and continue: 1978 / 618

Step 4:
1978 divided by 618 is 3 with a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 1854 from 1978, we get 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 618

Advancing to step 5:
618 goes into 1249 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 1236 from 1249 to get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 618

Going ahead to step 6:
618 can be fit into 133 0 times, resulting in a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 320.0
The remainder is 133 after subtracting 0 from 133.
Take the next digit (2) from the dividend and append it to 133, then repeat: 1332 / 618

Let's proceed to step 7:
618 goes into 1332 2 times with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 3202.0
Subtract 1236 from 1332 to get 96.
Fetch the next digit (3) from the dividend, attach it to 96 and continue: 963 / 618

Let's proceed to step 8:
618 goes into 963 1 times with a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 32021.0
If we take 618 away from 963, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 9:
618 can be fit into 3450 5 times, resulting in a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 32021.5
The remainder is 360 after subtracting 3090 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
The number 618 fits into 3600 5 times, leaving a remainder of 510.
The next digit of our result is 5. 
Result so far: 32021.55
The remainder is 510 after subtracting 3090 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

After the division, we end up with 32021.55 and a remainder of 0.51.
