72103245 divided by 491 
We want to figure out the number of times 72103245 can be divided by 491.

Going ahead to step 1:
491 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 491

Going ahead to step 2:
When dividing 72 by 491, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 491

Step 3:
The number 491 fits into 721 1 times, leaving a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 491 away from 721, we end up with 230.
Append the next digit (0) from the dividend to 230 and continue with: 2300 / 491

Let's proceed to step 4:
If we divide 2300 by 491, we get 4 and a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1964 from 2300 leaves us with 336.
Bring next digit (3) of the dividend behind the 336 and repeat the process: 3363 / 491

Going ahead to step 5:
When dividing 3363 by 491, we get 6 with a remainder of 417.
The next digit of our result is 6. 
Result so far: 146.0
If we subtract 2946 from 3363, we get 417.
Append the next digit (2) from the dividend to 417 and continue with: 4172 / 491

On to step 6:
When dividing 4172 by 491, we get 8 with a remainder of 244.
The next digit of our result is 8. 
Result so far: 1468.0
The remainder is 244 after subtracting 3928 from 4172.
Bring next digit (4) of the dividend behind the 244 and repeat the process: 2444 / 491

Step 7:
If we divide 2444 by 491, we get 4 and a remainder of 480.
The number 4 becomes the next digit in our result. 
Result so far: 14684.0
Subtract 1964 from 2444 to get 480.
Bring next digit (5) of the dividend behind the 480 and repeat the process: 4805 / 491

Advancing to step 8:
4805 divided by 491 is 9 with a remainder of 386.
Use 9 as the next digit of our solution. 
Result so far: 146849.0
If we take 4419 away from 4805, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 9:
If we divide 3860 by 491, we get 7 and a remainder of 423.
The number 7 becomes the next digit in our result. 
Result so far: 146849.7
The remainder is 423 after subtracting 3437 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 10:
491 can be fit into 4230 8 times, resulting in a remainder of 302.
Record the quotient 8 as the next digit in the result. 
Result so far: 146849.78
If we subtract 3928 from 4230, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 11:
The number 491 fits into 3020 6 times, leaving a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 146849.786
Deduct 2946 from 3020 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 12:
491 goes into 740 1 times with a remainder of 249.
Use 1 as the next digit of our solution. 
Result so far: 146849.7861
If we take 491 away from 740, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 13:
The number 491 fits into 2490 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 146849.78615
The remainder is 35 after subtracting 2455 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
491 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 146849.78615
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
If we divide 3500 by 491, we get 7 and a remainder of 63.
The next digit of our result is 7. 
Result so far: 146849.7861507
If we take 3437 away from 3500, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 16:
491 goes into 630 1 times with a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 146849.78615071
The remainder is 139 after subtracting 491 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

The quotient of the division is 146849.78615071, and the remainder is 1.39e-07.
