We divide 51087584 by 580
We want to figure out the number of times 51087584 can be divided by 580.

On to step 1:
When dividing 5 by 580, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 580

Going ahead to step 2:
51 divided by 580 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 580

Moving on to step 3:
If we divide 510 by 580, we get 0 and a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 510 and we're left with 510.
Grab the next digit (8) from the dividend, add it to 510, then carry on: 5108 / 580

Moving on to step 4:
580 goes into 5108 8 times with a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 4640 away from 5108, we end up with 468.
Bring next digit (7) of the dividend behind the 468 and repeat the process: 4687 / 580

Step 5:
The number 580 fits into 4687 8 times, leaving a remainder of 47.
The next digit of our result is 8. 
Result so far: 88.0
If we take 4640 away from 4687, we end up with 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 580

Moving on to step 6:
475 divided by 580 is 0 with a remainder of 475.
Record the quotient 0 as the next digit in the result. 
Result so far: 880.0
The remainder is 475 after subtracting 0 from 475.
Bring next digit (8) of the dividend behind the 475 and repeat the process: 4758 / 580

Going ahead to step 7:
The number 580 fits into 4758 8 times, leaving a remainder of 118.
Use 8 as the next digit of our solution. 
Result so far: 8808.0
If we subtract 4640 from 4758, we get 118.
Grab the next digit (4) from the dividend, add it to 118, then carry on: 1184 / 580

On to step 8:
If we divide 1184 by 580, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 88082.0
Subtract 1160 from 1184 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
580 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 88082.0
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
The number 580 fits into 2400 4 times, leaving a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 88082.04
Subtracting 2320 from 2400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
800 divided by 580 is 1 with a remainder of 220.
The next digit of our result is 1. 
Result so far: 88082.041
If we subtract 580 from 800, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 12:
When dividing 2200 by 580, we get 3 with a remainder of 460.
Record the quotient 3 as the next digit in the result. 
Result so far: 88082.0413
The remainder is 460 after subtracting 1740 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 13:
4600 divided by 580 is 7 with a remainder of 540.
Use 7 as the next digit of our solution. 
Result so far: 88082.04137
If we take 4060 away from 4600, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 14:
The number 580 fits into 5400 9 times, leaving a remainder of 180.
Write down 9 as next digit of the result. 
Result so far: 88082.041379
Deduct 5220 from 5400 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 15:
When dividing 1800 by 580, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 88082.0413793
Deduct 1740 from 1800 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
580 goes into 600 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 88082.04137931
The remainder is 20 after subtracting 580 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 88082.04137931, with a leftover of 2e-08.
