We're dividing 72852489 by 172 
Our goal is to divide 72852489 by 172.

Advancing to step 1:
172 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 172

Step 2:
When dividing 72 by 172, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 172

Going ahead to step 3:
728 divided by 172 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 40 after subtracting 688 from 728.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 172

Moving on to step 4:
If we divide 405 by 172, we get 2 and a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 344 away from 405, we end up with 61.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 172

Going ahead to step 5:
The number 172 fits into 612 3 times, leaving a remainder of 96.
The next digit of our result is 3. 
Result so far: 423.0
Deduct 516 from 612 and we're left with 96.
Grab the next digit (4) from the dividend, add it to 96, then carry on: 964 / 172

Step 6:
The number 172 fits into 964 5 times, leaving a remainder of 104.
Write down 5 as next digit of the result. 
Result so far: 4235.0
Subtract 860 from 964 to get 104.
Append the next digit (8) from the dividend to 104 and continue with: 1048 / 172

Going ahead to step 7:
When dividing 1048 by 172, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 42356.0
Subtract 1032 from 1048 to get 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 172

On to step 8:
If we divide 169 by 172, we get 0 and a remainder of 169.
Write down 0 as next digit of the result. 
Result so far: 423560.0
If we subtract 0 from 169, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 9:
172 can be fit into 1690 9 times, resulting in a remainder of 142.
The next digit of our result is 9. 
Result so far: 423560.9
The remainder is 142 after subtracting 1548 from 1690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
1420 divided by 172 is 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 423560.98
If we take 1376 away from 1420, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
The number 172 fits into 440 2 times, leaving a remainder of 96.
The next digit of our result is 2. 
Result so far: 423560.982
Deduct 344 from 440 and we're left with 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 12:
When dividing 960 by 172, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 423560.9825
If we take 860 away from 960, we end up 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.

Step 13:
When dividing 1000 by 172, we get 5 with a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 423560.98255
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 quotient of the division is 423560.98255, and the remainder is 0.00014.
