67678895 ÷ 172 
Let's see how many times 172 fits into 67678895.

Going ahead to step 1:
6 divided by 172 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 172

Moving on to step 2:
172 can be fit into 67 0 times, resulting in a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 172

On to step 3:
172 can be fit into 676 3 times, resulting in a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 516 away from 676, we end up with 160.
Fetch the next digit (7) from the dividend, attach it to 160 and continue: 1607 / 172

Moving on to step 4:
172 can be fit into 1607 9 times, resulting in a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Deduct 1548 from 1607 and we're left with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 172

Let's proceed to step 5:
When dividing 598 by 172, we get 3 with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
If we subtract 516 from 598, we get 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 172

Advancing to step 6:
172 goes into 828 4 times with a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 3934.0
If we subtract 688 from 828, we get 140.
Bring next digit (9) of the dividend behind the 140 and repeat the process: 1409 / 172

Let's proceed to step 7:
If we divide 1409 by 172, we get 8 and a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 39348.0
Subtracting 1376 from 1409 leaves us with 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 172

Let's proceed to step 8:
335 divided by 172 is 1 with a remainder of 163.
Record the quotient 1 as the next digit in the result. 
Result so far: 393481.0
If we take 172 away from 335, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 9:
1630 divided by 172 is 9 with a remainder of 82.
The next digit of our result is 9. 
Result so far: 393481.9
If we take 1548 away from 1630, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
When dividing 820 by 172, we get 4 with a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 393481.94
If we subtract 688 from 820, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
172 goes into 1320 7 times with a remainder of 116.
The number 7 becomes the next digit in our result. 
Result so far: 393481.947
If we take 1204 away from 1320, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
When dividing 1160 by 172, we get 6 with a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 393481.9476
Deduct 1032 from 1160 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 13:
The number 172 fits into 1280 7 times, leaving a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 393481.94767
If we take 1204 away from 1280, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
The number 172 fits into 760 4 times, leaving a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 393481.947674
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
If we divide 720 by 172, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 393481.9476744
Subtracting 688 from 720 leaves us with 32.
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 393481.9476744, with a leftover of 3.2e-07.
