172002 ÷ 70 
Let's see how many times 70 fits into 172002.

Step 1:
70 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 70

Moving on to step 2:
70 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 70

On to step 3:
70 goes into 172 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 140 from 172 and we're left with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 70

Going ahead to step 4:
70 goes into 320 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 280 from 320 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 70

Advancing to step 5:
If we divide 400 by 70, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 245.0
The remainder is 50 after subtracting 350 from 400.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 70

Let's proceed to step 6:
The number 70 fits into 502 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 2457.0
Subtracting 490 from 502 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 70 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 2457.1
The remainder is 50 after subtracting 70 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
70 goes into 500 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2457.17
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 2457.171
The remainder is 30 after subtracting 70 from 100.
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 10:
When dividing 300 by 70, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 2457.1714
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
70 goes into 200 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 2457.17142
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 12:
600 divided by 70 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 2457.171428
Deduct 560 from 600 and we're left 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.

On to step 13:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 2457.1714285
If we subtract 350 from 400, we get 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 14:
500 divided by 70 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2457.17142857
Subtract 490 from 500 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 2457.17142857 with a remaining 1e-08.
