We look at the division of 629870 by 53 
We're looking to find how many times 53 goes into 629870.

Moving on to step 1:
If we divide 6 by 53, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 53

Advancing to step 2:
If we divide 62 by 53, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 9 after subtracting 53 from 62.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 53

Let's proceed to step 3:
53 goes into 99 1 times with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 53 from 99, we get 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 53

Moving on to step 4:
If we divide 468 by 53, we get 8 and a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtract 424 from 468 to get 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 53

Going ahead to step 5:
53 goes into 447 8 times with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 1188.0
Deduct 424 from 447 and we're left with 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 53

On to step 6:
53 goes into 230 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 11884.0
Deduct 212 from 230 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
53 goes into 180 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 11884.3
The remainder is 21 after subtracting 159 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
If we divide 210 by 53, we get 3 and a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 11884.33
Subtract 159 from 210 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 11884.33 with a remainder of 0.051.
