Let's divide 211809 by 70
We want to figure out the number of times 211809 can be divided by 70.

Let's proceed to step 1:
If we divide 2 by 70, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 70

Step 2:
If we divide 21 by 70, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 70

Moving on to step 3:
211 divided by 70 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 210 from 211 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 70

Step 4:
70 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 70

On to step 5:
The number 70 fits into 180 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 302.0
If we take 140 away from 180, we end up with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 70

Moving on to step 6:
70 goes into 409 5 times with a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 3025.0
If we take 350 away from 409, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
If we divide 590 by 70, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 3025.8
Deduct 560 from 590 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.

Advancing to step 8:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3025.84
Deduct 280 from 300 and we're left 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.

Moving on to step 9:
When dividing 200 by 70, we get 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 3025.842
If we take 140 away from 200, we end up 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.

Let's proceed to step 10:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 3025.8428
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.

Let's proceed to step 11:
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: 3025.84285
Subtract 350 from 400 to 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.

Moving on to step 12:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 3025.842857
Deduct 490 from 500 and we're left with 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 13:
100 divided by 70 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 3025.8428571
If we take 70 away from 100, we end up 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.

On to step 14:
The number 70 fits into 300 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 3025.84285714
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.

Our division results in 3025.84285714 with a remaining 2e-08.
