We're dividing 78938852 by 497 
Let's see how many times 497 fits into 78938852.

Advancing to step 1:
497 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 497

Advancing to step 2:
78 divided by 497 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 497

Let's proceed to step 3:
789 divided by 497 is 1 with a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 497 from 789 leaves us with 292.
Append the next digit (3) from the dividend to 292 and continue with: 2923 / 497

On to step 4:
2923 divided by 497 is 5 with a remainder of 438.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2485 from 2923 leaves us with 438.
Fetch the next digit (8) from the dividend, attach it to 438 and continue: 4388 / 497

On to step 5:
If we divide 4388 by 497, we get 8 and a remainder of 412.
Write down 8 as next digit of the result. 
Result so far: 158.0
Deduct 3976 from 4388 and we're left with 412.
Append the next digit (8) from the dividend to 412 and continue with: 4128 / 497

Moving on to step 6:
If we divide 4128 by 497, we get 8 and a remainder of 152.
The next digit of our result is 8. 
Result so far: 1588.0
If we take 3976 away from 4128, we end up with 152.
Take the next digit (5) from the dividend and append it to 152, then repeat: 1525 / 497

Going ahead to step 7:
When dividing 1525 by 497, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 15883.0
Subtracting 1491 from 1525 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 497

Going ahead to step 8:
If we divide 342 by 497, we get 0 and a remainder of 342.
Record the quotient 0 as the next digit in the result. 
Result so far: 158830.0
Subtract 0 from 342 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 9:
The number 497 fits into 3420 6 times, leaving a remainder of 438.
Write down 6 as next digit of the result. 
Result so far: 158830.6
Deduct 2982 from 3420 and we're left with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

On to step 10:
4380 divided by 497 is 8 with a remainder of 404.
Record the quotient 8 as the next digit in the result. 
Result so far: 158830.68
If we take 3976 away from 4380, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 11:
497 goes into 4040 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 158830.688
If we subtract 3976 from 4040, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 158830.688, with a leftover of 0.0064.
