We're dividing 74320872 by 389 
Our goal is to divide 74320872 by 389.

On to step 1:
If we divide 7 by 389, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 389

Step 2:
When dividing 74 by 389, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 389

Let's proceed to step 3:
When dividing 743 by 389, we get 1 with a remainder of 354.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 389 from 743 leaves us with 354.
Take the next digit (2) from the dividend and append it to 354, then repeat: 3542 / 389

Step 4:
The number 389 fits into 3542 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 3501 from 3542 to get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 389

On to step 5:
If we divide 410 by 389, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 191.0
Subtract 389 from 410 to get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 389

Going ahead to step 6:
218 divided by 389 is 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 1910.0
If we subtract 0 from 218, we get 218.
Include the next digit (7) from the dividend after 218, then repeat: 2187 / 389

Moving on to step 7:
389 can be fit into 2187 5 times, resulting in a remainder of 242.
The next digit of our result is 5. 
Result so far: 19105.0
Deduct 1945 from 2187 and we're left with 242.
Include the next digit (2) from the dividend after 242, then repeat: 2422 / 389

Let's proceed to step 8:
When dividing 2422 by 389, we get 6 with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 191056.0
If we subtract 2334 from 2422, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 9:
The number 389 fits into 880 2 times, leaving a remainder of 102.
The next digit of our result is 2. 
Result so far: 191056.2
The remainder is 102 after subtracting 778 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Step 10:
389 goes into 1020 2 times with a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 191056.22
Deduct 778 from 1020 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 191056.22 and a remainder of 0.242.
