We divide 170190 by 70
Our goal is to divide 170190 by 70.

Step 1:
When dividing 1 by 70, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 70

Moving on to step 2:
17 divided by 70 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 70

Let's proceed to step 3:
70 goes into 170 2 times with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 30 after subtracting 140 from 170.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 70

Going ahead to step 4:
70 goes into 301 4 times with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 21 after subtracting 280 from 301.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 70

Moving on to step 5:
If we divide 219 by 70, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
Subtract 210 from 219 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 70

Moving on to step 6:
When dividing 90 by 70, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 2431.0
Subtract 70 from 90 to get 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 7:
If we divide 200 by 70, we get 2 and a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2431.2
Deduct 140 from 200 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.

Moving on to step 8:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 2431.28
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.

Advancing to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2431.285
Deduct 350 from 400 and we're left 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:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 2431.2857
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.

Step 11:
The number 70 fits into 100 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 2431.28571
Subtract 70 from 100 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
70 goes into 300 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 2431.285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 2431.2857142
If we subtract 140 from 200, we 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 14:
If we divide 600 by 70, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 2431.28571428
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.

The final result is 2431.28571428 with a remainder of 4e-08.
