Moving on to step 4:
210 goes into 1455 6 times with a remainder of 195.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we take 1260 away from 1455, we end up with 195.
Grab the next digit (9) from the dividend, add it to 195, then carry on: 1959 / 210

Advancing to step 5:
If we divide 1959 by 210, we get 9 and a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 469.0
Subtract 1890 from 1959 to get 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 210

Going ahead to step 6:
The number 210 fits into 693 3 times, leaving a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 4693.0
If we take 630 away from 693, we end up with 63.

Advancing to step 10:
The number 210 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 469330.3
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
The number 210 fits into 2000 9 times, leaving a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 469330.309
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
When dividing 1100 by 210, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 469330.3095
Subtract 1050 from 1100 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.

Advancing to step 13:
210 goes into 500 2 times with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 469330.30952
Deduct 420 from 500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
210 goes into 800 3 times with a remainder of 170.
Put 3 as the next digit of the answer. 
Result so far: 469330.309523
Deduct 630 from 800 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
1700 divided by 210 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 469330.3095238
Subtract 1680 from 1700 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.

Going ahead to step 16:
210 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 469330.3095238
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.
