171142 divided by 70 
We want to divide 171142 by 70.

Going ahead to step 1:
70 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 70

Let's proceed to step 2:
70 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 70

Advancing to step 3:
If we divide 171 by 70, we get 2 and a remainder of 31.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 140 from 171 and we're left with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 70

On to step 4:
If we divide 311 by 70, we get 4 and a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 280 away from 311, we end up with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 70

Moving on to step 5:
The number 70 fits into 314 4 times, leaving a remainder of 34.
The next digit of our result is 4. 
Result so far: 244.0
Subtract 280 from 314 to get 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 70

Step 6:
342 divided by 70 is 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 2444.0
Deduct 280 from 342 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
When dividing 620 by 70, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 2444.8
Deduct 560 from 620 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
70 can be fit into 600 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2444.88
Subtract 560 from 600 to 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.

The final outcome is 2444.88, with a leftover of 0.04.
