Let's divide 72154813 by 389
We're looking to find how many times 389 goes into 72154813.

Going ahead to step 1:
The number 389 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 389

Moving on to step 2:
72 divided by 389 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 389

Step 3:
If we divide 721 by 389, we get 1 and a remainder of 332.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 389 from 721 and we're left with 332.
Append the next digit (5) from the dividend to 332 and continue with: 3325 / 389

Moving on to step 4:
When dividing 3325 by 389, we get 8 with a remainder of 213.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 3112 from 3325 and we're left with 213.
Take the next digit (4) from the dividend and append it to 213, then repeat: 2134 / 389

Advancing to step 5:
389 can be fit into 2134 5 times, resulting in a remainder of 189.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
If we subtract 1945 from 2134, we get 189.
Append the next digit (8) from the dividend to 189 and continue with: 1898 / 389

Let's proceed to step 6:
1898 divided by 389 is 4 with a remainder of 342.
The next digit of our result is 4. 
Result so far: 1854.0
If we take 1556 away from 1898, we end up with 342.
Bring next digit (1) of the dividend behind the 342 and repeat the process: 3421 / 389

Advancing to step 7:
389 goes into 3421 8 times with a remainder of 309.
The number 8 becomes the next digit in our result. 
Result so far: 18548.0
Subtract 3112 from 3421 to get 309.
Fetch the next digit (3) from the dividend, attach it to 309 and continue: 3093 / 389

Going ahead to step 8:
389 goes into 3093 7 times with a remainder of 370.
The next digit of our result is 7. 
Result so far: 185487.0
Subtracting 2723 from 3093 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 9:
When dividing 3700 by 389, we get 9 with a remainder of 199.
The next digit of our result is 9. 
Result so far: 185487.9
The remainder is 199 after subtracting 3501 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 10:
When dividing 1990 by 389, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 185487.95
The remainder is 45 after subtracting 1945 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
389 goes into 450 1 times with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 185487.951
Subtracting 389 from 450 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
If we divide 610 by 389, we get 1 and a remainder of 221.
Put 1 as the next digit of the answer. 
Result so far: 185487.9511
If we take 389 away from 610, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The final result is 185487.9511 with a remainder of 0.00221.
