We divide 12122153 by 291
Our goal is to divide 12122153 by 291.

Let's proceed to step 1:
When dividing 1 by 291, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 291

Let's proceed to step 2:
The number 291 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 291

Step 3:
The number 291 fits into 121 0 times, leaving a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Fetch the next digit (2) from the dividend, attach it to 121 and continue: 1212 / 291

Moving on to step 4:
When dividing 1212 by 291, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1164 from 1212 to get 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 291

Going ahead to step 5:
291 goes into 482 1 times with a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
The remainder is 191 after subtracting 291 from 482.
Append the next digit (1) from the dividend to 191 and continue with: 1911 / 291

Advancing to step 6:
When dividing 1911 by 291, we get 6 with a remainder of 165.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Deduct 1746 from 1911 and we're left with 165.
Grab the next digit (5) from the dividend, add it to 165, then carry on: 1655 / 291

Going ahead to step 7:
If we divide 1655 by 291, we get 5 and a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 4165.0
If we subtract 1455 from 1655, we get 200.
Append the next digit (3) from the dividend to 200 and continue with: 2003 / 291

Advancing to step 8:
291 can be fit into 2003 6 times, resulting in a remainder of 257.
The number 6 becomes the next digit in our result. 
Result so far: 41656.0
If we subtract 1746 from 2003, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 9:
If we divide 2570 by 291, we get 8 and a remainder of 242.
Put 8 as the next digit of the answer. 
Result so far: 41656.8
The remainder is 242 after subtracting 2328 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 10:
The number 291 fits into 2420 8 times, leaving a remainder of 92.
The next digit of our result is 8. 
Result so far: 41656.88
If we take 2328 away from 2420, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

In conclusion, the division gives 41656.88 with a balance of 0.092.
