Append the next digit (6) from the dividend to 21 and continue with: 216 / 70

Going ahead to step 5:
70 can be fit into 216 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1233.0
Deduct 210 from 216 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 70

On to step 6:
68 divided by 70 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 12330.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 70

Step 7:
70 can be fit into 687 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 123309.0
Deduct 630 from 687 and we're left with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 70

Step 8:
70 goes into 575 8 times with a remainder of 15.
The next digit of our result is 8. 
Result so far: 1233098.0
Subtract 560 from 575 to 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 9:
When dividing 150 by 70, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 1233098.2
Deduct 140 from 150 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.

Let's proceed to step 10:
When dividing 100 by 70, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1233098.21
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.

Let's proceed to step 11:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 1233098.214
If we take 280 away from 300, we end up 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.

On to step 12:
200 divided by 70 is 2 with a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 1233098.2142
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.

On to step 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1233098.21428
The remainder is 40 after subtracting 560 from 600.
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 14:
The number 70 fits into 400 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1233098.214285
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.

Let's proceed to step 15:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1233098.2142857
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.

Let's proceed to step 16:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1233098.21428571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 1233098.21428571 with a balance of 3e-08.
