We divide 163690 by 70
We want to figure out the number of times 163690 can be divided by 70.

Going ahead to step 1:
1 divided by 70 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 70

On to step 2:
If we divide 16 by 70, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 70

Advancing to step 3:
If we divide 163 by 70, we get 2 and a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 140 from 163 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 70

On to step 4:
70 can be fit into 236 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 210 from 236 and we're left with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 70

On to step 5:
When dividing 269 by 70, we get 3 with a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 233.0
If we subtract 210 from 269, we get 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 70

Going ahead to step 6:
The number 70 fits into 590 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 2338.0
Subtracting 560 from 590 leaves us 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.

Moving on to step 7:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 2338.4
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.

Let's proceed to step 8:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 2338.42
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.

Let's proceed to step 9:
When dividing 600 by 70, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2338.428
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.

Step 10:
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: 2338.4285
Subtracting 350 from 400 leaves us 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.

Let's proceed to step 11:
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: 2338.42857
If we subtract 490 from 500, we 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 12:
70 can be fit into 100 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 2338.428571
Deduct 70 from 100 and we're left 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.

Let's proceed to step 13:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 2338.4285714
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.

On to step 14:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 2338.42857142
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.

The final result is 2338.42857142 with a remainder of 6e-08.
