We look at the division of 42848197 by 172 
Let's see how many times 172 fits into 42848197.

Going ahead to step 1:
172 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 172

Moving on to step 2:
42 divided by 172 is 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 172

Step 3:
172 goes into 428 2 times with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 344 from 428, we get 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 172

Advancing to step 4:
When dividing 844 by 172, we get 4 with a remainder of 156.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 688 from 844, we get 156.
Grab the next digit (8) from the dividend, add it to 156, then carry on: 1568 / 172

Step 5:
172 can be fit into 1568 9 times, resulting in a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Deduct 1548 from 1568 and we're left with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 172

Advancing to step 6:
If we divide 201 by 172, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 2491.0
If we take 172 away from 201, we end up with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 172

Let's proceed to step 7:
172 can be fit into 299 1 times, resulting in a remainder of 127.
Use 1 as the next digit of our solution. 
Result so far: 24911.0
If we take 172 away from 299, we end up with 127.
Bring next digit (7) of the dividend behind the 127 and repeat the process: 1277 / 172

Advancing to step 8:
If we divide 1277 by 172, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 249117.0
If we subtract 1204 from 1277, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 9:
172 can be fit into 730 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 249117.4
If we take 688 away from 730, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
172 goes into 420 2 times with a remainder of 76.
The next digit of our result is 2. 
Result so far: 249117.42
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
If we divide 760 by 172, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 249117.424
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
172 goes into 720 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 249117.4244
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 249117.4244, with a leftover of 0.00032.
