Let's divide 70159163 by 210
We're looking to find how many times 210 goes into 70159163.

Moving on to step 1:
210 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 210

Moving on to step 2:
The number 210 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 210

On to step 3:
701 divided by 210 is 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 630 from 701 leaves us with 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 210

Going ahead to step 4:
The number 210 fits into 715 3 times, leaving a remainder of 85.
The next digit of our result is 3. 
Result so far: 33.0
Deduct 630 from 715 and we're left with 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 210

On to step 5:
The number 210 fits into 859 4 times, leaving a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 334.0
The remainder is 19 after subtracting 840 from 859.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 210

On to step 6:
If we divide 191 by 210, we get 0 and a remainder of 191.
Use 0 as the next digit of our solution. 
Result so far: 3340.0
Deduct 0 from 191 and we're left with 191.
Append the next digit (6) from the dividend to 191 and continue with: 1916 / 210

Let's proceed to step 7:
If we divide 1916 by 210, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 33409.0
If we subtract 1890 from 1916, we get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 210

Going ahead to step 8:
210 can be fit into 263 1 times, resulting in a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 334091.0
Subtract 210 from 263 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
The number 210 fits into 530 2 times, leaving a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 334091.2
Subtract 420 from 530 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
The number 210 fits into 1100 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 334091.25
Deduct 1050 from 1100 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.

Moving on to step 11:
500 divided by 210 is 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 334091.252
Subtract 420 from 500 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
If we divide 800 by 210, we get 3 and a remainder of 170.
Write down 3 as next digit of the result. 
Result so far: 334091.2523
If we subtract 630 from 800, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 13:
210 goes into 1700 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 334091.25238
Subtracting 1680 from 1700 leaves us 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.

Advancing to step 14:
200 divided by 210 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 334091.25238
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
2000 divided by 210 is 9 with a remainder of 110.
The next digit of our result is 9. 
Result so far: 334091.2523809
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 16:
1100 divided by 210 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 334091.25238095
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 334091.25238095 and a remainder of 5e-08.
