57431289 divided by 798 
We're looking to find how many times 798 goes into 57431289.

Advancing to step 1:
When dividing 5 by 798, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 798

Moving on to step 2:
798 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 798

Let's proceed to step 3:
574 divided by 798 is 0 with a remainder of 574.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 574, we get 574.
Bring next digit (3) of the dividend behind the 574 and repeat the process: 5743 / 798

On to step 4:
798 can be fit into 5743 7 times, resulting in a remainder of 157.
The next digit of our result is 7. 
Result so far: 7.0
If we take 5586 away from 5743, we end up with 157.
Bring next digit (1) of the dividend behind the 157 and repeat the process: 1571 / 798

Moving on to step 5:
If we divide 1571 by 798, we get 1 and a remainder of 773.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 798 from 1571, we get 773.
Append the next digit (2) from the dividend to 773 and continue with: 7732 / 798

Moving on to step 6:
798 goes into 7732 9 times with a remainder of 550.
Write down 9 as next digit of the result. 
Result so far: 719.0
The remainder is 550 after subtracting 7182 from 7732.
Bring next digit (8) of the dividend behind the 550 and repeat the process: 5508 / 798

Advancing to step 7:
If we divide 5508 by 798, we get 6 and a remainder of 720.
The number 6 becomes the next digit in our result. 
Result so far: 7196.0
Subtract 4788 from 5508 to get 720.
Bring next digit (9) of the dividend behind the 720 and repeat the process: 7209 / 798

Let's proceed to step 8:
The number 798 fits into 7209 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 71969.0
Deduct 7182 from 7209 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
798 goes into 270 0 times with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 71969.0
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
When dividing 2700 by 798, we get 3 with a remainder of 306.
Record the quotient 3 as the next digit in the result. 
Result so far: 71969.03
If we subtract 2394 from 2700, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
798 goes into 3060 3 times with a remainder of 666.
The number 3 becomes the next digit in our result. 
Result so far: 71969.033
The remainder is 666 after subtracting 2394 from 3060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

The final outcome is 71969.033, with a leftover of 0.0666.
