We're dividing 68448309 by 172 
We want to divide 68448309 by 172.

Going ahead to step 1:
When dividing 6 by 172, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 172

Step 2:
The number 172 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 172

Let's proceed to step 3:
172 goes into 684 3 times with a remainder of 168.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 516 from 684 to get 168.
Fetch the next digit (4) from the dividend, attach it to 168 and continue: 1684 / 172

Moving on to step 4:
The number 172 fits into 1684 9 times, leaving a remainder of 136.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 1548 away from 1684, we end up with 136.
Include the next digit (8) from the dividend after 136, then repeat: 1368 / 172

Going ahead to step 5:
If we divide 1368 by 172, we get 7 and a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 397.0
If we take 1204 away from 1368, we end up with 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 172

Step 6:
172 can be fit into 1643 9 times, resulting in a remainder of 95.
The next digit of our result is 9. 
Result so far: 3979.0
The remainder is 95 after subtracting 1548 from 1643.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 172

Advancing to step 7:
172 goes into 950 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 39795.0
Deduct 860 from 950 and we're left with 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 172

Moving on to step 8:
172 can be fit into 909 5 times, resulting in a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 397955.0
If we subtract 860 from 909, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
490 divided by 172 is 2 with a remainder of 146.
Put 2 as the next digit of the answer. 
Result so far: 397955.2
Subtracting 344 from 490 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 10:
1460 divided by 172 is 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 397955.28
If we subtract 1376 from 1460, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
840 divided by 172 is 4 with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 397955.284
Subtracting 688 from 840 leaves us 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:
172 goes into 1520 8 times with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 397955.2848
The remainder is 144 after subtracting 1376 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
If we divide 1440 by 172, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 397955.28488
If we take 1376 away from 1440, we end up 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.

Our division results in 397955.28488 with a remaining 6.4e-05.
