79844251 ÷ 579 
We want to divide 79844251 by 579.

Step 1:
If we divide 7 by 579, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 579

Advancing to step 2:
The number 579 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 579

Let's proceed to step 3:
579 goes into 798 1 times with a remainder of 219.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 219 after subtracting 579 from 798.
Grab the next digit (4) from the dividend, add it to 219, then carry on: 2194 / 579

Advancing to step 4:
579 goes into 2194 3 times with a remainder of 457.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1737 from 2194, we get 457.
Include the next digit (4) from the dividend after 457, then repeat: 4574 / 579

Moving on to step 5:
4574 divided by 579 is 7 with a remainder of 521.
Write down 7 as next digit of the result. 
Result so far: 137.0
If we take 4053 away from 4574, we end up with 521.
Include the next digit (2) from the dividend after 521, then repeat: 5212 / 579

Going ahead to step 6:
The number 579 fits into 5212 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 1379.0
Subtract 5211 from 5212 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 579

Moving on to step 7:
579 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 13790.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 579

Going ahead to step 8:
If we divide 151 by 579, we get 0 and a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 137900.0
If we take 0 away from 151, we end up with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 9:
The number 579 fits into 1510 2 times, leaving a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 137900.2
Subtract 1158 from 1510 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 10:
3520 divided by 579 is 6 with a remainder of 46.
The next digit of our result is 6. 
Result so far: 137900.26
If we take 3474 away from 3520, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
579 can be fit into 460 0 times, resulting in a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 137900.26
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 12:
The number 579 fits into 4600 7 times, leaving a remainder of 547.
The number 7 becomes the next digit in our result. 
Result so far: 137900.2607
Subtract 4053 from 4600 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Going ahead to step 13:
5470 divided by 579 is 9 with a remainder of 259.
Put 9 as the next digit of the answer. 
Result so far: 137900.26079
Subtract 5211 from 5470 to get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 14:
When dividing 2590 by 579, we get 4 with a remainder of 274.
The number 4 becomes the next digit in our result. 
Result so far: 137900.260794
Subtracting 2316 from 2590 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 15:
When dividing 2740 by 579, we get 4 with a remainder of 424.
The number 4 becomes the next digit in our result. 
Result so far: 137900.2607944
Subtract 2316 from 2740 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

After the division, we end up with 137900.2607944 and a remainder of 4.24e-06.
