80509540 ÷ 712 
Our goal is to divide 80509540 by 712.

Step 1:
712 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 712

Going ahead to step 2:
The number 712 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 712

Step 3:
When dividing 805 by 712, we get 1 with a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 712 from 805 leaves us with 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 712

Step 4:
712 can be fit into 930 1 times, resulting in a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 712 from 930 leaves us with 218.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 712

Step 5:
2189 divided by 712 is 3 with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
If we take 2136 away from 2189, we end up with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 712

Advancing to step 6:
712 can be fit into 535 0 times, resulting in a remainder of 535.
The next digit of our result is 0. 
Result so far: 1130.0
If we take 0 away from 535, we end up with 535.
Bring next digit (4) of the dividend behind the 535 and repeat the process: 5354 / 712

Moving on to step 7:
5354 divided by 712 is 7 with a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 11307.0
If we take 4984 away from 5354, we end up with 370.
Append the next digit (0) from the dividend to 370 and continue with: 3700 / 712

Step 8:
When dividing 3700 by 712, we get 5 with a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 113075.0
If we take 3560 away from 3700, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 9:
712 goes into 1400 1 times with a remainder of 688.
Record the quotient 1 as the next digit in the result. 
Result so far: 113075.1
Subtract 712 from 1400 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 10:
When dividing 6880 by 712, we get 9 with a remainder of 472.
The number 9 becomes the next digit in our result. 
Result so far: 113075.19
Deduct 6408 from 6880 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 11:
712 goes into 4720 6 times with a remainder of 448.
The number 6 becomes the next digit in our result. 
Result so far: 113075.196
The remainder is 448 after subtracting 4272 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 12:
712 goes into 4480 6 times with a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 113075.1966
Subtract 4272 from 4480 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 113075.1966 and a remainder of 0.00208.
