We're dividing 210815 by 35 
We want to figure out the number of times 210815 can be divided by 35.

Advancing to step 1:
The number 35 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 35

Moving on to step 2:
If we divide 21 by 35, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 35

Let's proceed to step 3:
35 goes into 210 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 210 from 210, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 35

Let's proceed to step 4:
8 divided by 35 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 35

Let's proceed to step 5:
The number 35 fits into 81 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 602.0
If we take 70 away from 81, we end up with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 35

Let's proceed to step 6:
If we divide 115 by 35, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 6023.0
If we take 105 away from 115, we end up 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 7:
If we divide 100 by 35, we get 2 and a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 6023.2
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.

On to step 8:
If we divide 300 by 35, we get 8 and a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 6023.28
If we subtract 280 from 300, we 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.

Going ahead to step 9:
If we divide 200 by 35, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 6023.285
If we take 175 away from 200, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
When dividing 250 by 35, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 6023.2857
If we subtract 245 from 250, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
35 can be fit into 50 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 6023.28571
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 35, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 6023.285714
Subtract 140 from 150 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.

Let's proceed to step 13:
When dividing 100 by 35, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 6023.2857142
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.

Step 14:
35 goes into 300 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 6023.28571428
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.

The final result is 6023.28571428 with a remainder of 2e-08.
