We're dividing 20270502 by 172 
We want to divide 20270502 by 172.

Going ahead to step 1:
172 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 172

On to step 2:
172 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 172

Moving on to step 3:
202 divided by 172 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 172 from 202, we get 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 172

On to step 4:
172 can be fit into 307 1 times, resulting in a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 172 from 307, we get 135.
Include the next digit (0) from the dividend after 135, then repeat: 1350 / 172

Going ahead to step 5:
When dividing 1350 by 172, we get 7 with a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 117.0
The remainder is 146 after subtracting 1204 from 1350.
Bring next digit (5) of the dividend behind the 146 and repeat the process: 1465 / 172

Advancing to step 6:
If we divide 1465 by 172, we get 8 and a remainder of 89.
Record the quotient 8 as the next digit in the result. 
Result so far: 1178.0
If we take 1376 away from 1465, we end up with 89.
Include the next digit (0) from the dividend after 89, then repeat: 890 / 172

Advancing to step 7:
172 can be fit into 890 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 11785.0
If we take 860 away from 890, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 172

On to step 8:
If we divide 302 by 172, we get 1 and a remainder of 130.
Put 1 as the next digit of the answer. 
Result so far: 117851.0
The remainder is 130 after subtracting 172 from 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
172 goes into 1300 7 times with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 117851.7
The remainder is 96 after subtracting 1204 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
960 divided by 172 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 117851.75
Deduct 860 from 960 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
172 can be fit into 1000 5 times, resulting in a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 117851.755
Subtract 860 from 1000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 117851.755, with a leftover of 0.014.
