We look at the division of 25684872 by 121 
Let's see how many times 121 fits into 25684872.

Going ahead to step 1:
2 divided by 121 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 121

Let's proceed to step 2:
If we divide 25 by 121, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 121

Step 3:
256 divided by 121 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 242 away from 256, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 121

Step 4:
148 divided by 121 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 121 from 148, we get 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 121

Going ahead to step 5:
274 divided by 121 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 212.0
If we take 242 away from 274, we end up with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 121

Let's proceed to step 6:
The number 121 fits into 328 2 times, leaving a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 2122.0
Subtracting 242 from 328 leaves us with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 121

Step 7:
When dividing 867 by 121, we get 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 21227.0
Deduct 847 from 867 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 121

Going ahead to step 8:
When dividing 202 by 121, we get 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 212271.0
Subtract 121 from 202 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 9:
The number 121 fits into 810 6 times, leaving a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 212271.6
Deduct 726 from 810 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
840 divided by 121 is 6 with a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 212271.66
Deduct 726 from 840 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 212271.66 with a remainder of 0.114.
