We look at the division of 84357039 by 581 
Let's see how many times 581 fits into 84357039.

Going ahead to step 1:
581 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 581

Advancing to step 2:
The number 581 fits into 84 0 times, leaving a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (3) from the dividend, attach it to 84 and continue: 843 / 581

Going ahead to step 3:
581 goes into 843 1 times with a remainder of 262.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 581 from 843 leaves us with 262.
Take the next digit (5) from the dividend and append it to 262, then repeat: 2625 / 581

Moving on to step 4:
581 can be fit into 2625 4 times, resulting in a remainder of 301.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 2324 from 2625 to get 301.
Bring next digit (7) of the dividend behind the 301 and repeat the process: 3017 / 581

On to step 5:
The number 581 fits into 3017 5 times, leaving a remainder of 112.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtract 2905 from 3017 to get 112.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 581

Going ahead to step 6:
The number 581 fits into 1120 1 times, leaving a remainder of 539.
Write down 1 as next digit of the result. 
Result so far: 1451.0
The remainder is 539 after subtracting 581 from 1120.
Bring next digit (3) of the dividend behind the 539 and repeat the process: 5393 / 581

Let's proceed to step 7:
When dividing 5393 by 581, we get 9 with a remainder of 164.
The number 9 becomes the next digit in our result. 
Result so far: 14519.0
If we subtract 5229 from 5393, we get 164.
Include the next digit (9) from the dividend after 164, then repeat: 1649 / 581

Let's proceed to step 8:
When dividing 1649 by 581, we get 2 with a remainder of 487.
Record the quotient 2 as the next digit in the result. 
Result so far: 145192.0
If we take 1162 away from 1649, we end up with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

On to step 9:
581 can be fit into 4870 8 times, resulting in a remainder of 222.
The next digit of our result is 8. 
Result so far: 145192.8
If we take 4648 away from 4870, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 10:
581 can be fit into 2220 3 times, resulting in a remainder of 477.
Write down 3 as next digit of the result. 
Result so far: 145192.83
If we take 1743 away from 2220, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 11:
4770 divided by 581 is 8 with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 145192.838
If we subtract 4648 from 4770, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 12:
When dividing 1220 by 581, we get 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 145192.8382
Subtract 1162 from 1220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 13:
581 can be fit into 580 0 times, resulting in a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 145192.8382
Subtracting 0 from 580 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 14:
581 goes into 5800 9 times with a remainder of 571.
Write down 9 as next digit of the result. 
Result so far: 145192.838209
Subtracting 5229 from 5800 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Step 15:
581 can be fit into 5710 9 times, resulting in a remainder of 481.
Put 9 as the next digit of the answer. 
Result so far: 145192.8382099
Subtracting 5229 from 5710 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

After the division, we end up with 145192.8382099 and a remainder of 4.81e-06.
