We divide 80648686 by 580
We want to divide 80648686 by 580.

Going ahead to step 1:
When dividing 8 by 580, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 580

Step 2:
580 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 580

Let's proceed to step 3:
The number 580 fits into 806 1 times, leaving a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 580 from 806 and we're left with 226.
Take the next digit (4) from the dividend and append it to 226, then repeat: 2264 / 580

Let's proceed to step 4:
If we divide 2264 by 580, we get 3 and a remainder of 524.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1740 away from 2264, we end up with 524.
Take the next digit (8) from the dividend and append it to 524, then repeat: 5248 / 580

Let's proceed to step 5:
When dividing 5248 by 580, we get 9 with a remainder of 28.
The next digit of our result is 9. 
Result so far: 139.0
Subtract 5220 from 5248 to get 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 580

Step 6:
When dividing 286 by 580, we get 0 with a remainder of 286.
The next digit of our result is 0. 
Result so far: 1390.0
Deduct 0 from 286 and we're left with 286.
Append the next digit (8) from the dividend to 286 and continue with: 2868 / 580

Going ahead to step 7:
580 can be fit into 2868 4 times, resulting in a remainder of 548.
The number 4 becomes the next digit in our result. 
Result so far: 13904.0
Deduct 2320 from 2868 and we're left with 548.
Grab the next digit (6) from the dividend, add it to 548, then carry on: 5486 / 580

Let's proceed to step 8:
580 can be fit into 5486 9 times, resulting in a remainder of 266.
Use 9 as the next digit of our solution. 
Result so far: 139049.0
Subtracting 5220 from 5486 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
If we divide 2660 by 580, we get 4 and a remainder of 340.
Record the quotient 4 as the next digit in the result. 
Result so far: 139049.4
Deduct 2320 from 2660 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
The number 580 fits into 3400 5 times, leaving a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 139049.45
The remainder is 500 after subtracting 2900 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 11:
5000 divided by 580 is 8 with a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 139049.458
If we take 4640 away from 5000, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 12:
The number 580 fits into 3600 6 times, leaving a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 139049.4586
Deduct 3480 from 3600 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
If we divide 1200 by 580, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 139049.45862
If we subtract 1160 from 1200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 580 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 139049.45862
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
If we divide 4000 by 580, we get 6 and a remainder of 520.
The number 6 becomes the next digit in our result. 
Result so far: 139049.4586206
Subtract 3480 from 4000 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 16:
580 goes into 5200 8 times with a remainder of 560.
Put 8 as the next digit of the answer. 
Result so far: 139049.45862068
If we take 4640 away from 5200, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 139049.45862068, with a leftover of 5.6e-07.
