We look at the division of 57916403 by 80 
Our goal is to divide 57916403 by 80.

Step 1:
80 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 80

Step 2:
When dividing 57 by 80, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 80

Let's proceed to step 3:
80 goes into 579 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 560 from 579 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 80

Let's proceed to step 4:
When dividing 191 by 80, we get 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we take 160 away from 191, we end up with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 80

On to step 5:
80 can be fit into 316 3 times, resulting in a remainder of 76.
Use 3 as the next digit of our solution. 
Result so far: 723.0
If we take 240 away from 316, we end up with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 80

Moving on to step 6:
When dividing 764 by 80, we get 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 7239.0
The remainder is 44 after subtracting 720 from 764.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 80

Let's proceed to step 7:
If we divide 440 by 80, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 72395.0
The remainder is 40 after subtracting 400 from 440.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 80

Step 8:
The number 80 fits into 403 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 723955.0
Subtract 400 from 403 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 80 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 723955.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 723955.03
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
If we divide 600 by 80, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 723955.037
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 723955.0375
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 723955.0375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 723955.0375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 723955.0375 and a remainder of 0.0.
