We're dividing 99758069 by 579 
We want to divide 99758069 by 579.

Let's proceed to step 1:
When dividing 9 by 579, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 579

Moving on to step 2:
579 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 579

Advancing to step 3:
When dividing 997 by 579, we get 1 with a remainder of 418.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 579 from 997, we get 418.
Take the next digit (5) from the dividend and append it to 418, then repeat: 4185 / 579

Let's proceed to step 4:
4185 divided by 579 is 7 with a remainder of 132.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 4053 from 4185 leaves us with 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 579

Moving on to step 5:
579 can be fit into 1328 2 times, resulting in a remainder of 170.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we subtract 1158 from 1328, we get 170.
Append the next digit (0) from the dividend to 170 and continue with: 1700 / 579

Advancing to step 6:
1700 divided by 579 is 2 with a remainder of 542.
Record the quotient 2 as the next digit in the result. 
Result so far: 1722.0
Subtracting 1158 from 1700 leaves us with 542.
Bring next digit (6) of the dividend behind the 542 and repeat the process: 5426 / 579

Moving on to step 7:
579 goes into 5426 9 times with a remainder of 215.
The number 9 becomes the next digit in our result. 
Result so far: 17229.0
If we subtract 5211 from 5426, we get 215.
Bring next digit (9) of the dividend behind the 215 and repeat the process: 2159 / 579

Let's proceed to step 8:
579 goes into 2159 3 times with a remainder of 422.
Record the quotient 3 as the next digit in the result. 
Result so far: 172293.0
Subtract 1737 from 2159 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 9:
If we divide 4220 by 579, we get 7 and a remainder of 167.
The next digit of our result is 7. 
Result so far: 172293.7
Subtracting 4053 from 4220 leaves us with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 10:
1670 divided by 579 is 2 with a remainder of 512.
Use 2 as the next digit of our solution. 
Result so far: 172293.72
If we take 1158 away from 1670, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 11:
The number 579 fits into 5120 8 times, leaving a remainder of 488.
Write down 8 as next digit of the result. 
Result so far: 172293.728
The remainder is 488 after subtracting 4632 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 12:
579 can be fit into 4880 8 times, resulting in a remainder of 248.
The next digit of our result is 8. 
Result so far: 172293.7288
The remainder is 248 after subtracting 4632 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The quotient of the division is 172293.7288, and the remainder is 0.00248.
