We divide 53855103 by 249
We want to divide 53855103 by 249.

Moving on to step 1:
The number 249 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 249

Step 2:
53 divided by 249 is 0 with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 249

Step 3:
When dividing 538 by 249, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 498 from 538 to get 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 249

Going ahead to step 4:
If we divide 405 by 249, we get 1 and a remainder of 156.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 249 away from 405, we end up with 156.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 249

Moving on to step 5:
249 goes into 1565 6 times with a remainder of 71.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Deduct 1494 from 1565 and we're left with 71.
Bring next digit (1) of the dividend behind the 71 and repeat the process: 711 / 249

On to step 6:
711 divided by 249 is 2 with a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 2162.0
If we take 498 away from 711, we end up with 213.
Take the next digit (0) from the dividend and append it to 213, then repeat: 2130 / 249

On to step 7:
249 goes into 2130 8 times with a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 21628.0
Deduct 1992 from 2130 and we're left with 138.
Grab the next digit (3) from the dividend, add it to 138, then carry on: 1383 / 249

Let's proceed to step 8:
249 can be fit into 1383 5 times, resulting in a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 216285.0
If we take 1245 away from 1383, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 9:
When dividing 1380 by 249, we get 5 with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 216285.5
Deduct 1245 from 1380 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
The number 249 fits into 1350 5 times, leaving a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 216285.55
If we take 1245 away from 1350, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 216285.55, and the remainder is 0.105.
