Let's divide 20397917 by 491
We're looking to find how many times 491 goes into 20397917.

Let's proceed to step 1:
When dividing 2 by 491, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 491

On to step 2:
When dividing 20 by 491, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 491

Step 3:
491 goes into 203 0 times with a remainder of 203.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 203 and we're left with 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 491

Step 4:
When dividing 2039 by 491, we get 4 with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1964 from 2039 and we're left with 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 491

Step 5:
491 goes into 757 1 times with a remainder of 266.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 491 from 757 leaves us with 266.
Include the next digit (9) from the dividend after 266, then repeat: 2669 / 491

Let's proceed to step 6:
When dividing 2669 by 491, we get 5 with a remainder of 214.
Use 5 as the next digit of our solution. 
Result so far: 415.0
Subtracting 2455 from 2669 leaves us with 214.
Append the next digit (1) from the dividend to 214 and continue with: 2141 / 491

Going ahead to step 7:
491 can be fit into 2141 4 times, resulting in a remainder of 177.
The number 4 becomes the next digit in our result. 
Result so far: 4154.0
The remainder is 177 after subtracting 1964 from 2141.
Include the next digit (7) from the dividend after 177, then repeat: 1777 / 491

Let's proceed to step 8:
1777 divided by 491 is 3 with a remainder of 304.
The number 3 becomes the next digit in our result. 
Result so far: 41543.0
If we take 1473 away from 1777, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 9:
When dividing 3040 by 491, we get 6 with a remainder of 94.
Write down 6 as next digit of the result. 
Result so far: 41543.6
The remainder is 94 after subtracting 2946 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
When dividing 940 by 491, we get 1 with a remainder of 449.
The number 1 becomes the next digit in our result. 
Result so far: 41543.61
Subtract 491 from 940 to get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 11:
491 can be fit into 4490 9 times, resulting in a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 41543.619
If we take 4419 away from 4490, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
If we divide 710 by 491, we get 1 and a remainder of 219.
Use 1 as the next digit of our solution. 
Result so far: 41543.6191
Subtracting 491 from 710 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 13:
491 goes into 2190 4 times with a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 41543.61914
Subtract 1964 from 2190 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.

Let's proceed to step 14:
The number 491 fits into 2260 4 times, leaving a remainder of 296.
The next digit of our result is 4. 
Result so far: 41543.619144
Subtracting 1964 from 2260 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 41543.619144, with a leftover of 2.96e-05.
