We divide 99978577 by 572
We want to figure out the number of times 99978577 can be divided by 572.

Step 1:
If we divide 9 by 572, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 572

Let's proceed to step 2:
572 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 572

Step 3:
When dividing 999 by 572, we get 1 with a remainder of 427.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 427 after subtracting 572 from 999.
Fetch the next digit (7) from the dividend, attach it to 427 and continue: 4277 / 572

Step 4:
When dividing 4277 by 572, we get 7 with a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 4004 from 4277 leaves us with 273.
Take the next digit (8) from the dividend and append it to 273, then repeat: 2738 / 572

Moving on to step 5:
The number 572 fits into 2738 4 times, leaving a remainder of 450.
Use 4 as the next digit of our solution. 
Result so far: 174.0
Subtract 2288 from 2738 to get 450.
Append the next digit (5) from the dividend to 450 and continue with: 4505 / 572

Going ahead to step 6:
If we divide 4505 by 572, we get 7 and a remainder of 501.
Write down 7 as next digit of the result. 
Result so far: 1747.0
If we take 4004 away from 4505, we end up with 501.
Take the next digit (7) from the dividend and append it to 501, then repeat: 5017 / 572

Moving on to step 7:
572 can be fit into 5017 8 times, resulting in a remainder of 441.
Put 8 as the next digit of the answer. 
Result so far: 17478.0
If we subtract 4576 from 5017, we get 441.
Append the next digit (7) from the dividend to 441 and continue with: 4417 / 572

On to step 8:
The number 572 fits into 4417 7 times, leaving a remainder of 413.
The next digit of our result is 7. 
Result so far: 174787.0
Subtract 4004 from 4417 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 9:
572 goes into 4130 7 times with a remainder of 126.
Put 7 as the next digit of the answer. 
Result so far: 174787.7
Subtract 4004 from 4130 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 10:
572 can be fit into 1260 2 times, resulting in a remainder of 116.
Use 2 as the next digit of our solution. 
Result so far: 174787.72
If we take 1144 away from 1260, we end up 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:
572 can be fit into 1160 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 174787.722
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.

The final outcome is 174787.722, with a leftover of 0.0016.
