We look at the division of 755616 by 172 
We want to figure out the number of times 755616 can be divided by 172.

Advancing to step 1:
The number 172 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 172

Step 2:
172 can be fit into 75 0 times, resulting in a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 172

Let's proceed to step 3:
172 can be fit into 755 4 times, resulting in a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 688 from 755 leaves us with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 172

Moving on to step 4:
When dividing 676 by 172, we get 3 with a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 516 from 676, we get 160.
Take the next digit (1) from the dividend and append it to 160, then repeat: 1601 / 172

Step 5:
1601 divided by 172 is 9 with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 439.0
Subtracting 1548 from 1601 leaves us with 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 172

Let's proceed to step 6:
536 divided by 172 is 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 4393.0
Deduct 516 from 536 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
172 goes into 200 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 4393.1
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
If we divide 280 by 172, we get 1 and a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 4393.11
Deduct 172 from 280 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 4393.11, with a leftover of 0.108.
