81494447 ÷ 580 
We want to divide 81494447 by 580.

Let's proceed to step 1:
580 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 580

Going ahead to step 2:
580 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 580

Going ahead to step 3:
If we divide 814 by 580, we get 1 and a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 580 away from 814, we end up with 234.
Grab the next digit (9) from the dividend, add it to 234, then carry on: 2349 / 580

Step 4:
When dividing 2349 by 580, we get 4 with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 2320 away from 2349, we end up with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 580

Let's proceed to step 5:
294 divided by 580 is 0 with a remainder of 294.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtract 0 from 294 to get 294.
Append the next digit (4) from the dividend to 294 and continue with: 2944 / 580

On to step 6:
580 can be fit into 2944 5 times, resulting in a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 1405.0
Subtracting 2900 from 2944 leaves us with 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 580

Advancing to step 7:
When dividing 444 by 580, we get 0 with a remainder of 444.
The number 0 becomes the next digit in our result. 
Result so far: 14050.0
Subtract 0 from 444 to get 444.
Append the next digit (7) from the dividend to 444 and continue with: 4447 / 580

Moving on to step 8:
4447 divided by 580 is 7 with a remainder of 387.
Use 7 as the next digit of our solution. 
Result so far: 140507.0
Subtracting 4060 from 4447 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 9:
If we divide 3870 by 580, we get 6 and a remainder of 390.
Record the quotient 6 as the next digit in the result. 
Result so far: 140507.6
Subtracting 3480 from 3870 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
When dividing 3900 by 580, we get 6 with a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 140507.66
The remainder is 420 after subtracting 3480 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 140507.66, and the remainder is 0.42.
