84309603 ÷ 491 
Our goal is to divide 84309603 by 491.

Let's proceed to step 1:
491 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 491

On to step 2:
The number 491 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 take 0 away from 84, we end up with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 491

Advancing to step 3:
843 divided by 491 is 1 with a remainder of 352.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 491 from 843 leaves us with 352.
Grab the next digit (0) from the dividend, add it to 352, then carry on: 3520 / 491

Going ahead to step 4:
The number 491 fits into 3520 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 3437 from 3520, we get 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 491

Let's proceed to step 5:
The number 491 fits into 839 1 times, leaving a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Deduct 491 from 839 and we're left with 348.
Include the next digit (6) from the dividend after 348, then repeat: 3486 / 491

On to step 6:
3486 divided by 491 is 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 1717.0
Subtract 3437 from 3486 to get 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 491

Going ahead to step 7:
490 divided by 491 is 0 with a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 17170.0
If we take 0 away from 490, we end up with 490.
Append the next digit (3) from the dividend to 490 and continue with: 4903 / 491

Step 8:
491 can be fit into 4903 9 times, resulting in a remainder of 484.
Write down 9 as next digit of the result. 
Result so far: 171709.0
The remainder is 484 after subtracting 4419 from 4903.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 9:
If we divide 4840 by 491, we get 9 and a remainder of 421.
The next digit of our result is 9. 
Result so far: 171709.9
If we subtract 4419 from 4840, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 10:
When dividing 4210 by 491, we get 8 with a remainder of 282.
Write down 8 as next digit of the result. 
Result so far: 171709.98
Subtracting 3928 from 4210 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 11:
When dividing 2820 by 491, we get 5 with a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 171709.985
The remainder is 365 after subtracting 2455 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Going ahead to step 12:
491 can be fit into 3650 7 times, resulting in a remainder of 213.
Write down 7 as next digit of the result. 
Result so far: 171709.9857
Subtracting 3437 from 3650 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 13:
If we divide 2130 by 491, we get 4 and a remainder of 166.
Put 4 as the next digit of the answer. 
Result so far: 171709.98574
If we subtract 1964 from 2130, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
The number 491 fits into 1660 3 times, leaving a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 171709.985743
Subtracting 1473 from 1660 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Moving on to step 15:
491 can be fit into 1870 3 times, resulting in a remainder of 397.
Put 3 as the next digit of the answer. 
Result so far: 171709.9857433
If we take 1473 away from 1870, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

The quotient of the division is 171709.9857433, and the remainder is 3.97e-06.
