80104102 ÷ 579 
We're looking to find how many times 579 goes into 80104102.

Let's proceed to step 1:
579 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 579

Moving on to step 2:
If we divide 80 by 579, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 579

Step 3:
579 can be fit into 801 1 times, resulting in a remainder of 222.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 579 from 801 and we're left with 222.
Append the next digit (0) from the dividend to 222 and continue with: 2220 / 579

Let's proceed to step 4:
The number 579 fits into 2220 3 times, leaving a remainder of 483.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1737 from 2220 to get 483.
Bring next digit (4) of the dividend behind the 483 and repeat the process: 4834 / 579

Step 5:
579 goes into 4834 8 times with a remainder of 202.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtracting 4632 from 4834 leaves us with 202.
Append the next digit (1) from the dividend to 202 and continue with: 2021 / 579

Advancing to step 6:
The number 579 fits into 2021 3 times, leaving a remainder of 284.
Use 3 as the next digit of our solution. 
Result so far: 1383.0
Deduct 1737 from 2021 and we're left with 284.
Grab the next digit (0) from the dividend, add it to 284, then carry on: 2840 / 579

Let's proceed to step 7:
The number 579 fits into 2840 4 times, leaving a remainder of 524.
Put 4 as the next digit of the answer. 
Result so far: 13834.0
Deduct 2316 from 2840 and we're left with 524.
Append the next digit (2) from the dividend to 524 and continue with: 5242 / 579

Advancing to step 8:
If we divide 5242 by 579, we get 9 and a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 138349.0
If we take 5211 away from 5242, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
If we divide 310 by 579, we get 0 and a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 138349.0
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
The number 579 fits into 3100 5 times, leaving a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 138349.05
If we take 2895 away from 3100, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 11:
579 can be fit into 2050 3 times, resulting in a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 138349.053
If we subtract 1737 from 2050, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 12:
When dividing 3130 by 579, we get 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 138349.0535
Subtract 2895 from 3130 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 13:
579 goes into 2350 4 times with a remainder of 34.
The next digit of our result is 4. 
Result so far: 138349.05354
Subtracting 2316 from 2350 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
579 can be fit into 340 0 times, resulting in a remainder of 340.
The next digit of our result is 0. 
Result so far: 138349.05354
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 15:
579 can be fit into 3400 5 times, resulting in a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 138349.0535405
The remainder is 505 after subtracting 2895 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 16:
If we divide 5050 by 579, we get 8 and a remainder of 418.
Record the quotient 8 as the next digit in the result. 
Result so far: 138349.05354058
Subtract 4632 from 5050 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 138349.05354058, with a leftover of 4.18e-07.
