25413670 divided by 211 
Our goal is to divide 25413670 by 211.

Moving on to step 1:
The number 211 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 211

Going ahead to step 2:
When dividing 25 by 211, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 211

Advancing to step 3:
The number 211 fits into 254 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 43 after subtracting 211 from 254.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 211

On to step 4:
211 goes into 431 2 times with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 9 after subtracting 422 from 431.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 211

Advancing to step 5:
93 divided by 211 is 0 with a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtracting 0 from 93 leaves us with 93.
Bring next digit (6) of the dividend behind the 93 and repeat the process: 936 / 211

Going ahead to step 6:
211 can be fit into 936 4 times, resulting in a remainder of 92.
Put 4 as the next digit of the answer. 
Result so far: 1204.0
Subtract 844 from 936 to get 92.
Take the next digit (7) from the dividend and append it to 92, then repeat: 927 / 211

Advancing to step 7:
927 divided by 211 is 4 with a remainder of 83.
The number 4 becomes the next digit in our result. 
Result so far: 12044.0
If we take 844 away from 927, we end up with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 211

Let's proceed to step 8:
If we divide 830 by 211, we get 3 and a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 120443.0
Deduct 633 from 830 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 9:
211 goes into 1970 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 120443.9
Subtracting 1899 from 1970 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
211 can be fit into 710 3 times, resulting in a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 120443.93
Deduct 633 from 710 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.

Going ahead to step 11:
The number 211 fits into 770 3 times, leaving a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 120443.933
Subtracting 633 from 770 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The final outcome is 120443.933, with a leftover of 0.0137.
