We're dividing 67580530 by 491 
We want to divide 67580530 by 491.

Step 1:
491 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 491

On to step 2:
If we divide 67 by 491, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 491

Step 3:
491 goes into 675 1 times with a remainder of 184.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 184 after subtracting 491 from 675.
Grab the next digit (8) from the dividend, add it to 184, then carry on: 1848 / 491

Moving on to step 4:
The number 491 fits into 1848 3 times, leaving a remainder of 375.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 1473 from 1848 and we're left with 375.
Append the next digit (0) from the dividend to 375 and continue with: 3750 / 491

Moving on to step 5:
491 can be fit into 3750 7 times, resulting in a remainder of 313.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we subtract 3437 from 3750, we get 313.
Fetch the next digit (5) from the dividend, attach it to 313 and continue: 3135 / 491

Moving on to step 6:
The number 491 fits into 3135 6 times, leaving a remainder of 189.
Record the quotient 6 as the next digit in the result. 
Result so far: 1376.0
If we subtract 2946 from 3135, we get 189.
Fetch the next digit (3) from the dividend, attach it to 189 and continue: 1893 / 491

Step 7:
The number 491 fits into 1893 3 times, leaving a remainder of 420.
Use 3 as the next digit of our solution. 
Result so far: 13763.0
If we take 1473 away from 1893, we end up with 420.
Take the next digit (0) from the dividend and append it to 420, then repeat: 4200 / 491

Advancing to step 8:
The number 491 fits into 4200 8 times, leaving a remainder of 272.
The next digit of our result is 8. 
Result so far: 137638.0
Subtract 3928 from 4200 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
491 goes into 2720 5 times with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 137638.5
Deduct 2455 from 2720 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
2650 divided by 491 is 5 with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 137638.55
If we take 2455 away from 2650, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 137638.55, with a leftover of 0.195.
