We look at the division of 4538556 by 172 
Let's see how many times 172 fits into 4538556.

Moving on to step 1:
When dividing 4 by 172, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 172

On to step 2:
45 divided by 172 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 172

Moving on to step 3:
If we divide 453 by 172, we get 2 and a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 344 from 453 to get 109.
Take the next digit (8) from the dividend and append it to 109, then repeat: 1098 / 172

Going ahead to step 4:
If we divide 1098 by 172, we get 6 and a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtracting 1032 from 1098 leaves us with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 172

Going ahead to step 5:
The number 172 fits into 665 3 times, leaving a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 263.0
If we take 516 away from 665, we end up with 149.
Bring next digit (5) of the dividend behind the 149 and repeat the process: 1495 / 172

Let's proceed to step 6:
1495 divided by 172 is 8 with a remainder of 119.
Put 8 as the next digit of the answer. 
Result so far: 2638.0
Subtract 1376 from 1495 to get 119.
Bring next digit (6) of the dividend behind the 119 and repeat the process: 1196 / 172

Moving on to step 7:
172 goes into 1196 6 times with a remainder of 164.
The next digit of our result is 6. 
Result so far: 26386.0
Subtract 1032 from 1196 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 8:
When dividing 1640 by 172, we get 9 with a remainder of 92.
The next digit of our result is 9. 
Result so far: 26386.9
Subtract 1548 from 1640 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
If we divide 920 by 172, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 26386.95
Subtract 860 from 920 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
172 can be fit into 600 3 times, resulting in a remainder of 84.
Write down 3 as next digit of the result. 
Result so far: 26386.953
The remainder is 84 after subtracting 516 from 600.
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 11:
172 goes into 840 4 times with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 26386.9534
If we take 688 away from 840, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 12:
1520 divided by 172 is 8 with a remainder of 144.
The next digit of our result is 8. 
Result so far: 26386.95348
Subtract 1376 from 1520 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 13:
When dividing 1440 by 172, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 26386.953488
Subtracting 1376 from 1440 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 26386.953488 with a remainder of 6.4e-06.
