Let's divide 84903161 by 573
We want to divide 84903161 by 573.

Step 1:
If we divide 8 by 573, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 573

On to step 2:
When dividing 84 by 573, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 573

Moving on to step 3:
If we divide 849 by 573, we get 1 and a remainder of 276.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 573 from 849, we get 276.
Take the next digit (0) from the dividend and append it to 276, then repeat: 2760 / 573

On to step 4:
When dividing 2760 by 573, we get 4 with a remainder of 468.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 2292 from 2760 and we're left with 468.
Append the next digit (3) from the dividend to 468 and continue with: 4683 / 573

On to step 5:
If we divide 4683 by 573, we get 8 and a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we subtract 4584 from 4683, we get 99.
Grab the next digit (1) from the dividend, add it to 99, then carry on: 991 / 573

Going ahead to step 6:
If we divide 991 by 573, we get 1 and a remainder of 418.
Use 1 as the next digit of our solution. 
Result so far: 1481.0
If we take 573 away from 991, we end up with 418.
Include the next digit (6) from the dividend after 418, then repeat: 4186 / 573

Moving on to step 7:
When dividing 4186 by 573, we get 7 with a remainder of 175.
Record the quotient 7 as the next digit in the result. 
Result so far: 14817.0
The remainder is 175 after subtracting 4011 from 4186.
Take the next digit (1) from the dividend and append it to 175, then repeat: 1751 / 573

Going ahead to step 8:
When dividing 1751 by 573, we get 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 148173.0
Deduct 1719 from 1751 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
The number 573 fits into 320 0 times, leaving a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 148173.0
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
If we divide 3200 by 573, we get 5 and a remainder of 335.
The next digit of our result is 5. 
Result so far: 148173.05
If we take 2865 away from 3200, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 11:
When dividing 3350 by 573, we get 5 with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 148173.055
If we take 2865 away from 3350, we end up with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

The quotient of the division is 148173.055, and the remainder is 0.0485.
