Let's divide 87873953 by 172
Let's see how many times 172 fits into 87873953.

Moving on to step 1:
172 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 172

Moving on to step 2:
172 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 172

On to step 3:
878 divided by 172 is 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 860 from 878 to get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 172

Step 4:
The number 172 fits into 187 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 172 from 187 to get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 172

Let's proceed to step 5:
When dividing 153 by 172, we get 0 with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Subtracting 0 from 153 leaves us with 153.
Fetch the next digit (9) from the dividend, attach it to 153 and continue: 1539 / 172

Step 6:
1539 divided by 172 is 8 with a remainder of 163.
Use 8 as the next digit of our solution. 
Result so far: 5108.0
Subtracting 1376 from 1539 leaves us with 163.
Take the next digit (5) from the dividend and append it to 163, then repeat: 1635 / 172

Advancing to step 7:
1635 divided by 172 is 9 with a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 51089.0
If we subtract 1548 from 1635, we get 87.
Grab the next digit (3) from the dividend, add it to 87, then carry on: 873 / 172

Step 8:
The number 172 fits into 873 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 510895.0
Subtracting 860 from 873 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 172 is 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 510895.0
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
When dividing 1300 by 172, we get 7 with a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 510895.07
Subtract 1204 from 1300 to get 96.
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 11:
If we divide 960 by 172, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 510895.075
Subtract 860 from 960 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
172 goes into 1000 5 times with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 510895.0755
Deduct 860 from 1000 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 510895.0755 with a remaining 0.0014.
