We divide 172878 by 70
Our goal is to divide 172878 by 70.

Step 1:
70 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 70

Moving on to step 2:
70 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 70

Moving on to step 3:
If we divide 172 by 70, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 140 away from 172, we end up with 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 70

Step 4:
The number 70 fits into 328 4 times, leaving a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 48 after subtracting 280 from 328.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 70

Going ahead to step 5:
70 goes into 487 6 times with a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtracting 420 from 487 leaves us with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 70

On to step 6:
The number 70 fits into 678 9 times, leaving a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 2469.0
Subtracting 630 from 678 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
If we divide 480 by 70, we get 6 and a remainder of 60.
The next digit of our result is 6. 
Result so far: 2469.6
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 2469.68
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 70, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 2469.685
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 2469.6857
The remainder is 10 after subtracting 490 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
If we divide 100 by 70, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 2469.68571
If we take 70 away from 100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 2469.685714
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 2469.6857142
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2469.68571428
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 2469.68571428, with a leftover of 4e-08.
