We look at the division of 81356412 by 585 
Let's see how many times 585 fits into 81356412.

Let's proceed to step 1:
585 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 585

On to step 2:
585 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 585

Advancing to step 3:
If we divide 813 by 585, we get 1 and a remainder of 228.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 585 away from 813, we end up with 228.
Fetch the next digit (5) from the dividend, attach it to 228 and continue: 2285 / 585

Advancing to step 4:
The number 585 fits into 2285 3 times, leaving a remainder of 530.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1755 from 2285 leaves us with 530.
Bring next digit (6) of the dividend behind the 530 and repeat the process: 5306 / 585

Advancing to step 5:
When dividing 5306 by 585, we get 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we subtract 5265 from 5306, we get 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 585

Advancing to step 6:
The number 585 fits into 414 0 times, leaving a remainder of 414.
Write down 0 as next digit of the result. 
Result so far: 1390.0
If we take 0 away from 414, we end up with 414.
Include the next digit (1) from the dividend after 414, then repeat: 4141 / 585

Moving on to step 7:
4141 divided by 585 is 7 with a remainder of 46.
The next digit of our result is 7. 
Result so far: 13907.0
The remainder is 46 after subtracting 4095 from 4141.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 585

On to step 8:
If we divide 462 by 585, we get 0 and a remainder of 462.
The next digit of our result is 0. 
Result so far: 139070.0
If we subtract 0 from 462, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 9:
When dividing 4620 by 585, we get 7 with a remainder of 525.
Write down 7 as next digit of the result. 
Result so far: 139070.7
The remainder is 525 after subtracting 4095 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 10:
When dividing 5250 by 585, we get 8 with a remainder of 570.
Record the quotient 8 as the next digit in the result. 
Result so far: 139070.78
The remainder is 570 after subtracting 4680 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 11:
If we divide 5700 by 585, we get 9 and a remainder of 435.
Write down 9 as next digit of the result. 
Result so far: 139070.789
Subtracting 5265 from 5700 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 12:
585 can be fit into 4350 7 times, resulting in a remainder of 255.
Record the quotient 7 as the next digit in the result. 
Result so far: 139070.7897
If we subtract 4095 from 4350, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 13:
When dividing 2550 by 585, we get 4 with a remainder of 210.
Put 4 as the next digit of the answer. 
Result so far: 139070.78974
Deduct 2340 from 2550 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
When dividing 2100 by 585, we get 3 with a remainder of 345.
Put 3 as the next digit of the answer. 
Result so far: 139070.789743
If we subtract 1755 from 2100, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 15:
If we divide 3450 by 585, we get 5 and a remainder of 525.
The number 5 becomes the next digit in our result. 
Result so far: 139070.7897435
Deduct 2925 from 3450 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 16:
The number 585 fits into 5250 8 times, leaving a remainder of 570.
The next digit of our result is 8. 
Result so far: 139070.78974358
Deduct 4680 from 5250 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

In conclusion, the division gives 139070.78974358 with a balance of 5.7e-07.
