We're dividing 79889984 by 821 
Our goal is to divide 79889984 by 821.

On to step 1:
The number 821 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 821

Going ahead to step 2:
79 divided by 821 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 821

Step 3:
The number 821 fits into 798 0 times, leaving a remainder of 798.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 798 to get 798.
Append the next digit (8) from the dividend to 798 and continue with: 7988 / 821

Going ahead to step 4:
821 can be fit into 7988 9 times, resulting in a remainder of 599.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7389 from 7988, we get 599.
Take the next digit (9) from the dividend and append it to 599, then repeat: 5999 / 821

Moving on to step 5:
821 goes into 5999 7 times with a remainder of 252.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtracting 5747 from 5999 leaves us with 252.
Append the next digit (9) from the dividend to 252 and continue with: 2529 / 821

Moving on to step 6:
If we divide 2529 by 821, we get 3 and a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 973.0
Deduct 2463 from 2529 and we're left with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 821

On to step 7:
821 can be fit into 668 0 times, resulting in a remainder of 668.
The next digit of our result is 0. 
Result so far: 9730.0
Subtracting 0 from 668 leaves us with 668.
Take the next digit (4) from the dividend and append it to 668, then repeat: 6684 / 821

Let's proceed to step 8:
When dividing 6684 by 821, we get 8 with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 97308.0
If we subtract 6568 from 6684, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 9:
821 goes into 1160 1 times with a remainder of 339.
Use 1 as the next digit of our solution. 
Result so far: 97308.1
If we take 821 away from 1160, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 10:
3390 divided by 821 is 4 with a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 97308.14
Subtracting 3284 from 3390 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
821 goes into 1060 1 times with a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 97308.141
If we take 821 away from 1060, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 12:
The number 821 fits into 2390 2 times, leaving a remainder of 748.
The number 2 becomes the next digit in our result. 
Result so far: 97308.1412
The remainder is 748 after subtracting 1642 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Moving on to step 13:
821 goes into 7480 9 times with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 97308.14129
Deduct 7389 from 7480 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 14:
The number 821 fits into 910 1 times, leaving a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 97308.141291
If we subtract 821 from 910, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 15:
821 goes into 890 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 97308.1412911
Deduct 821 from 890 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 97308.1412911 and a remainder of 6.9e-07.
