We're dividing 74079990 by 286 
We want to figure out the number of times 74079990 can be divided by 286.

Moving on to step 1:
If we divide 7 by 286, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 286

Going ahead to step 2:
When dividing 74 by 286, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 286

Going ahead to step 3:
286 goes into 740 2 times with a remainder of 168.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 168 after subtracting 572 from 740.
Take the next digit (7) from the dividend and append it to 168, then repeat: 1687 / 286

Advancing to step 4:
If we divide 1687 by 286, we get 5 and a remainder of 257.
The next digit of our result is 5. 
Result so far: 25.0
If we take 1430 away from 1687, we end up with 257.
Include the next digit (9) from the dividend after 257, then repeat: 2579 / 286

Moving on to step 5:
286 can be fit into 2579 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 259.0
Deduct 2574 from 2579 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 286

Moving on to step 6:
59 divided by 286 is 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 2590.0
If we subtract 0 from 59, we get 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 286

Step 7:
When dividing 599 by 286, we get 2 with a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 25902.0
Deduct 572 from 599 and we're left with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 286

Going ahead to step 8:
When dividing 270 by 286, we get 0 with a remainder of 270.
The number 0 becomes the next digit in our result. 
Result so far: 259020.0
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 9:
2700 divided by 286 is 9 with a remainder of 126.
The next digit of our result is 9. 
Result so far: 259020.9
Deduct 2574 from 2700 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 10:
1260 divided by 286 is 4 with a remainder of 116.
Put 4 as the next digit of the answer. 
Result so far: 259020.94
Subtracting 1144 from 1260 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 11:
286 can be fit into 1160 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 259020.944
If we subtract 1144 from 1160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 259020.944 with a balance of 0.0016.
