We divide 79400805 by 497
We want to divide 79400805 by 497.

Step 1:
497 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 497

Let's proceed to step 2:
If we divide 79 by 497, we get 0 and a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (4) from the dividend, attach it to 79 and continue: 794 / 497

Moving on to step 3:
When dividing 794 by 497, we get 1 with a remainder of 297.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 497 from 794 to get 297.
Take the next digit (0) from the dividend and append it to 297, then repeat: 2970 / 497

Advancing to step 4:
497 can be fit into 2970 5 times, resulting in a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 485 after subtracting 2485 from 2970.
Append the next digit (0) from the dividend to 485 and continue with: 4850 / 497

Going ahead to step 5:
4850 divided by 497 is 9 with a remainder of 377.
Write down 9 as next digit of the result. 
Result so far: 159.0
Deduct 4473 from 4850 and we're left with 377.
Grab the next digit (8) from the dividend, add it to 377, then carry on: 3778 / 497

Step 6:
497 can be fit into 3778 7 times, resulting in a remainder of 299.
Put 7 as the next digit of the answer. 
Result so far: 1597.0
The remainder is 299 after subtracting 3479 from 3778.
Bring next digit (0) of the dividend behind the 299 and repeat the process: 2990 / 497

Going ahead to step 7:
The number 497 fits into 2990 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 15976.0
If we take 2982 away from 2990, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 497

Going ahead to step 8:
When dividing 85 by 497, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 159760.0
Subtracting 0 from 85 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
497 goes into 850 1 times with a remainder of 353.
Record the quotient 1 as the next digit in the result. 
Result so far: 159760.1
Deduct 497 from 850 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 10:
When dividing 3530 by 497, we get 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 159760.17
If we take 3479 away from 3530, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
497 can be fit into 510 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 159760.171
If we subtract 497 from 510, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
497 goes into 130 0 times with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 159760.171
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 13:
1300 divided by 497 is 2 with a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 159760.17102
Subtract 994 from 1300 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 14:
If we divide 3060 by 497, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 159760.171026
If we take 2982 away from 3060, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 15:
780 divided by 497 is 1 with a remainder of 283.
The number 1 becomes the next digit in our result. 
Result so far: 159760.1710261
Subtracting 497 from 780 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 16:
The number 497 fits into 2830 5 times, leaving a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 159760.17102615
Subtract 2485 from 2830 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

After the division, we end up with 159760.17102615 and a remainder of 3.45e-07.
