We're dividing 83159823 by 102 
Let's see how many times 102 fits into 83159823.

On to step 1:
The number 102 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 102

Advancing to step 2:
The number 102 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 102

Going ahead to step 3:
102 goes into 831 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 816 from 831 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 102

Let's proceed to step 4:
If we divide 155 by 102, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtracting 102 from 155 leaves us with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 102

Let's proceed to step 5:
The number 102 fits into 539 5 times, leaving a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 815.0
Deduct 510 from 539 and we're left with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 102

Going ahead to step 6:
If we divide 298 by 102, we get 2 and a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 8152.0
If we subtract 204 from 298, we get 94.
Grab the next digit (2) from the dividend, add it to 94, then carry on: 942 / 102

Let's proceed to step 7:
102 can be fit into 942 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 81529.0
If we take 918 away from 942, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 102

Advancing to step 8:
If we divide 243 by 102, we get 2 and a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 815292.0
If we subtract 204 from 243, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
The number 102 fits into 390 3 times, leaving a remainder of 84.
The next digit of our result is 3. 
Result so far: 815292.3
Subtracting 306 from 390 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
102 goes into 840 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 815292.38
The remainder is 24 after subtracting 816 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
102 can be fit into 240 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 815292.382
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
If we divide 360 by 102, we get 3 and a remainder of 54.
Use 3 as the next digit of our solution. 
Result so far: 815292.3823
If we subtract 306 from 360, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
540 divided by 102 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 815292.38235
Subtracting 510 from 540 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
300 divided by 102 is 2 with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 815292.382352
Subtract 204 from 300 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
When dividing 960 by 102, we get 9 with a remainder of 42.
Use 9 as the next digit of our solution. 
Result so far: 815292.3823529
Deduct 918 from 960 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 16:
102 can be fit into 420 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 815292.38235294
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 815292.38235294, with a leftover of 1.2e-08.
