We look at the division of 83415391 by 573 
We want to divide 83415391 by 573.

On to step 1:
When dividing 8 by 573, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 573

Step 2:
573 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 573

Let's proceed to step 3:
573 can be fit into 834 1 times, resulting in a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 573 from 834 to get 261.
Include the next digit (1) from the dividend after 261, then repeat: 2611 / 573

Step 4:
When dividing 2611 by 573, we get 4 with a remainder of 319.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2292 from 2611 to get 319.
Bring next digit (5) of the dividend behind the 319 and repeat the process: 3195 / 573

Step 5:
3195 divided by 573 is 5 with a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Deduct 2865 from 3195 and we're left with 330.
Append the next digit (3) from the dividend to 330 and continue with: 3303 / 573

Let's proceed to step 6:
If we divide 3303 by 573, we get 5 and a remainder of 438.
Write down 5 as next digit of the result. 
Result so far: 1455.0
Subtracting 2865 from 3303 leaves us with 438.
Grab the next digit (9) from the dividend, add it to 438, then carry on: 4389 / 573

Going ahead to step 7:
When dividing 4389 by 573, we get 7 with a remainder of 378.
Put 7 as the next digit of the answer. 
Result so far: 14557.0
Subtracting 4011 from 4389 leaves us with 378.
Grab the next digit (1) from the dividend, add it to 378, then carry on: 3781 / 573

Let's proceed to step 8:
If we divide 3781 by 573, we get 6 and a remainder of 343.
Put 6 as the next digit of the answer. 
Result so far: 145576.0
The remainder is 343 after subtracting 3438 from 3781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
The number 573 fits into 3430 5 times, leaving a remainder of 565.
Use 5 as the next digit of our solution. 
Result so far: 145576.5
Deduct 2865 from 3430 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 10:
When dividing 5650 by 573, we get 9 with a remainder of 493.
The number 9 becomes the next digit in our result. 
Result so far: 145576.59
If we take 5157 away from 5650, we end up with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 11:
4930 divided by 573 is 8 with a remainder of 346.
The next digit of our result is 8. 
Result so far: 145576.598
Subtract 4584 from 4930 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 12:
When dividing 3460 by 573, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 145576.5986
The remainder is 22 after subtracting 3438 from 3460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
If we divide 220 by 573, we get 0 and a remainder of 220.
The next digit of our result is 0. 
Result so far: 145576.5986
Deduct 0 from 220 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.

On to step 14:
When dividing 2200 by 573, we get 3 with a remainder of 481.
Record the quotient 3 as the next digit in the result. 
Result so far: 145576.598603
If we take 1719 away from 2200, we end up 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.

Step 15:
When dividing 4810 by 573, we get 8 with a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 145576.5986038
Subtract 4584 from 4810 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 16:
The number 573 fits into 2260 3 times, leaving a remainder of 541.
The number 3 becomes the next digit in our result. 
Result so far: 145576.59860383
The remainder is 541 after subtracting 1719 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Our division results in 145576.59860383 with a remaining 5.41e-07.
