79579872 divided by 821 
Let's see how many times 821 fits into 79579872.

Advancing to step 1:
821 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 821

On to step 2:
If we divide 79 by 821, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 821

Moving on to step 3:
The number 821 fits into 795 0 times, leaving a remainder of 795.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 795 after subtracting 0 from 795.
Fetch the next digit (7) from the dividend, attach it to 795 and continue: 7957 / 821

On to step 4:
7957 divided by 821 is 9 with a remainder of 568.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7389 away from 7957, we end up with 568.
Bring next digit (9) of the dividend behind the 568 and repeat the process: 5689 / 821

Let's proceed to step 5:
821 can be fit into 5689 6 times, resulting in a remainder of 763.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we subtract 4926 from 5689, we get 763.
Fetch the next digit (8) from the dividend, attach it to 763 and continue: 7638 / 821

On to step 6:
The number 821 fits into 7638 9 times, leaving a remainder of 249.
Write down 9 as next digit of the result. 
Result so far: 969.0
Deduct 7389 from 7638 and we're left with 249.
Grab the next digit (7) from the dividend, add it to 249, then carry on: 2497 / 821

Let's proceed to step 7:
821 goes into 2497 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 9693.0
If we subtract 2463 from 2497, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 821

Moving on to step 8:
821 can be fit into 342 0 times, resulting in a remainder of 342.
Record the quotient 0 as the next digit in the result. 
Result so far: 96930.0
If we subtract 0 from 342, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 9:
When dividing 3420 by 821, we get 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 96930.4
The remainder is 136 after subtracting 3284 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
If we divide 1360 by 821, we get 1 and a remainder of 539.
Put 1 as the next digit of the answer. 
Result so far: 96930.41
Deduct 821 from 1360 and we're left with 539.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5390, and continue the process.

Moving on to step 11:
The number 821 fits into 5390 6 times, leaving a remainder of 464.
Record the quotient 6 as the next digit in the result. 
Result so far: 96930.416
Subtract 4926 from 5390 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 12:
The number 821 fits into 4640 5 times, leaving a remainder of 535.
The next digit of our result is 5. 
Result so far: 96930.4165
Subtracting 4105 from 4640 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 13:
821 can be fit into 5350 6 times, resulting in a remainder of 424.
Write down 6 as next digit of the result. 
Result so far: 96930.41656
Subtract 4926 from 5350 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.

Step 14:
The number 821 fits into 4240 5 times, leaving a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 96930.416565
If we subtract 4105 from 4240, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 15:
821 goes into 1350 1 times with a remainder of 529.
The number 1 becomes the next digit in our result. 
Result so far: 96930.4165651
Subtract 821 from 1350 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 16:
5290 divided by 821 is 6 with a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 96930.41656516
If we take 4926 away from 5290, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

In conclusion, the division gives 96930.41656516 with a balance of 3.64e-07.
