We're dividing 34278131 by 121 
Let's see how many times 121 fits into 34278131.

Going ahead to step 1:
3 divided by 121 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 121

Going ahead to step 2:
If we divide 34 by 121, we get 0 and a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 121

Step 3:
The number 121 fits into 342 2 times, leaving a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 242 from 342 leaves us with 100.
Grab the next digit (7) from the dividend, add it to 100, then carry on: 1007 / 121

On to step 4:
121 goes into 1007 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 39 after subtracting 968 from 1007.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 121

On to step 5:
When dividing 398 by 121, we get 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 283.0
Subtract 363 from 398 to get 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 121

Step 6:
121 goes into 351 2 times with a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 2832.0
Deduct 242 from 351 and we're left with 109.
Include the next digit (3) from the dividend after 109, then repeat: 1093 / 121

Moving on to step 7:
The number 121 fits into 1093 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 28329.0
The remainder is 4 after subtracting 1089 from 1093.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 121

Advancing to step 8:
41 divided by 121 is 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 283290.0
The remainder is 41 after subtracting 0 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
121 can be fit into 410 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 283290.3
If we take 363 away from 410, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 10:
If we divide 470 by 121, we get 3 and a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 283290.33
Subtract 363 from 470 to get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

After the division, we end up with 283290.33 and a remainder of 0.107.
