We're dividing 53800483 by 210 
We're looking to find how many times 210 goes into 53800483.

Step 1:
210 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 210

Step 2:
210 goes into 53 0 times with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 210

Going ahead to step 3:
210 can be fit into 538 2 times, resulting in a remainder of 118.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 420 away from 538, we end up with 118.
Append the next digit (0) from the dividend to 118 and continue with: 1180 / 210

Going ahead to step 4:
1180 divided by 210 is 5 with a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 1050 from 1180 to get 130.
Grab the next digit (0) from the dividend, add it to 130, then carry on: 1300 / 210

Going ahead to step 5:
210 goes into 1300 6 times with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
If we subtract 1260 from 1300, we get 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 210

On to step 6:
210 can be fit into 404 1 times, resulting in a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 2561.0
Subtracting 210 from 404 leaves us with 194.
Bring next digit (8) of the dividend behind the 194 and repeat the process: 1948 / 210

On to step 7:
If we divide 1948 by 210, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 25619.0
Subtracting 1890 from 1948 leaves us with 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 210

Going ahead to step 8:
583 divided by 210 is 2 with a remainder of 163.
Write down 2 as next digit of the result. 
Result so far: 256192.0
If we subtract 420 from 583, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
The number 210 fits into 1630 7 times, leaving a remainder of 160.
Record the quotient 7 as the next digit in the result. 
Result so far: 256192.7
If we subtract 1470 from 1630, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
1600 divided by 210 is 7 with a remainder of 130.
Record the quotient 7 as the next digit in the result. 
Result so far: 256192.77
If we subtract 1470 from 1600, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Our division results in 256192.77 with a remaining 0.13.
