We're dividing 28616786 by 172 
We want to divide 28616786 by 172.

Let's proceed to step 1:
172 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 172

Advancing to step 2:
28 divided by 172 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 172

Going ahead to step 3:
The number 172 fits into 286 1 times, leaving a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 114 after subtracting 172 from 286.
Fetch the next digit (1) from the dividend, attach it to 114 and continue: 1141 / 172

Step 4:
The number 172 fits into 1141 6 times, leaving a remainder of 109.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 1032 from 1141 and we're left with 109.
Append the next digit (6) from the dividend to 109 and continue with: 1096 / 172

Let's proceed to step 5:
1096 divided by 172 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 166.0
Subtract 1032 from 1096 to get 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 172

Going ahead to step 6:
The number 172 fits into 647 3 times, leaving a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 1663.0
Subtracting 516 from 647 leaves us with 131.
Take the next digit (8) from the dividend and append it to 131, then repeat: 1318 / 172

Step 7:
When dividing 1318 by 172, we get 7 with a remainder of 114.
Put 7 as the next digit of the answer. 
Result so far: 16637.0
Subtract 1204 from 1318 to get 114.
Bring next digit (6) of the dividend behind the 114 and repeat the process: 1146 / 172

Advancing to step 8:
If we divide 1146 by 172, we get 6 and a remainder of 114.
Use 6 as the next digit of our solution. 
Result so far: 166376.0
Subtracting 1032 from 1146 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
The number 172 fits into 1140 6 times, leaving a remainder of 108.
The next digit of our result is 6. 
Result so far: 166376.6
Subtract 1032 from 1140 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 10:
The number 172 fits into 1080 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 166376.66
Subtract 1032 from 1080 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 166376.66, with a leftover of 0.048.
