81684040 ÷ 585 
Our goal is to divide 81684040 by 585.

On to step 1:
If we divide 8 by 585, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 585

Let's proceed to step 2:
When dividing 81 by 585, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 585

Advancing to step 3:
585 goes into 816 1 times with a remainder of 231.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 585 from 816 leaves us with 231.
Append the next digit (8) from the dividend to 231 and continue with: 2318 / 585

Let's proceed to step 4:
2318 divided by 585 is 3 with a remainder of 563.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1755 from 2318, we get 563.
Grab the next digit (4) from the dividend, add it to 563, then carry on: 5634 / 585

Let's proceed to step 5:
5634 divided by 585 is 9 with a remainder of 369.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Deduct 5265 from 5634 and we're left with 369.
Grab the next digit (0) from the dividend, add it to 369, then carry on: 3690 / 585

Moving on to step 6:
If we divide 3690 by 585, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 1396.0
If we take 3510 away from 3690, we end up with 180.
Fetch the next digit (4) from the dividend, attach it to 180 and continue: 1804 / 585

Let's proceed to step 7:
The number 585 fits into 1804 3 times, leaving a remainder of 49.
Record the quotient 3 as the next digit in the result. 
Result so far: 13963.0
Subtracting 1755 from 1804 leaves us with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 585

Step 8:
585 can be fit into 490 0 times, resulting in a remainder of 490.
The next digit of our result is 0. 
Result so far: 139630.0
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 9:
4900 divided by 585 is 8 with a remainder of 220.
Record the quotient 8 as the next digit in the result. 
Result so far: 139630.8
Deduct 4680 from 4900 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
If we divide 2200 by 585, we get 3 and a remainder of 445.
Write down 3 as next digit of the result. 
Result so far: 139630.83
Subtracting 1755 from 2200 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 11:
585 can be fit into 4450 7 times, resulting in a remainder of 355.
The next digit of our result is 7. 
Result so far: 139630.837
If we subtract 4095 from 4450, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 12:
585 goes into 3550 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 139630.8376
The remainder is 40 after subtracting 3510 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 585 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 139630.8376
If we take 0 away from 400, we end up 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.

Moving on to step 14:
585 can be fit into 4000 6 times, resulting in a remainder of 490.
The number 6 becomes the next digit in our result. 
Result so far: 139630.837606
If we subtract 3510 from 4000, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 15:
The number 585 fits into 4900 8 times, leaving a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 139630.8376068
If we take 4680 away from 4900, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 16:
If we divide 2200 by 585, we get 3 and a remainder of 445.
Put 3 as the next digit of the answer. 
Result so far: 139630.83760683
Subtracting 1755 from 2200 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

The final outcome is 139630.83760683, with a leftover of 4.45e-07.
