55310297 divided by 210 
We want to divide 55310297 by 210.

On to step 1:
210 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 210

On to step 2:
The number 210 fits into 55 0 times, leaving a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (3) from the dividend, attach it to 55 and continue: 553 / 210

Going ahead to step 3:
The number 210 fits into 553 2 times, leaving a remainder of 133.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 420 away from 553, we end up with 133.
Include the next digit (1) from the dividend after 133, then repeat: 1331 / 210

On to step 4:
1331 divided by 210 is 6 with a remainder of 71.
The next digit of our result is 6. 
Result so far: 26.0
If we take 1260 away from 1331, we end up with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 210

On to step 5:
The number 210 fits into 710 3 times, leaving a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 263.0
Subtract 630 from 710 to get 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 210

Let's proceed to step 6:
210 can be fit into 802 3 times, resulting in a remainder of 172.
The number 3 becomes the next digit in our result. 
Result so far: 2633.0
The remainder is 172 after subtracting 630 from 802.
Bring next digit (9) of the dividend behind the 172 and repeat the process: 1729 / 210

Advancing to step 7:
210 can be fit into 1729 8 times, resulting in a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 26338.0
Subtract 1680 from 1729 to get 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 210

Let's proceed to step 8:
The number 210 fits into 497 2 times, leaving a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 263382.0
Deduct 420 from 497 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
770 divided by 210 is 3 with a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 263382.3
The remainder is 140 after subtracting 630 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
210 can be fit into 1400 6 times, resulting in a remainder of 140.
Write down 6 as next digit of the result. 
Result so far: 263382.36
Subtracting 1260 from 1400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
If we divide 1400 by 210, we get 6 and a remainder of 140.
Use 6 as the next digit of our solution. 
Result so far: 263382.366
If we take 1260 away from 1400, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 263382.366 with a remaining 0.014.
