We look at the division of 43154121 by 841 
Let's see how many times 841 fits into 43154121.

Going ahead to step 1:
The number 841 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 841

Moving on to step 2:
841 can be fit into 43 0 times, resulting in a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 841

Step 3:
841 goes into 431 0 times with a remainder of 431.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 431 leaves us with 431.
Take the next digit (5) from the dividend and append it to 431, then repeat: 4315 / 841

Moving on to step 4:
4315 divided by 841 is 5 with a remainder of 110.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 110 after subtracting 4205 from 4315.
Fetch the next digit (4) from the dividend, attach it to 110 and continue: 1104 / 841

Advancing to step 5:
1104 divided by 841 is 1 with a remainder of 263.
The next digit of our result is 1. 
Result so far: 51.0
Subtracting 841 from 1104 leaves us with 263.
Grab the next digit (1) from the dividend, add it to 263, then carry on: 2631 / 841

Going ahead to step 6:
841 can be fit into 2631 3 times, resulting in a remainder of 108.
Use 3 as the next digit of our solution. 
Result so far: 513.0
If we subtract 2523 from 2631, we get 108.
Include the next digit (2) from the dividend after 108, then repeat: 1082 / 841

Advancing to step 7:
When dividing 1082 by 841, we get 1 with a remainder of 241.
Use 1 as the next digit of our solution. 
Result so far: 5131.0
If we subtract 841 from 1082, we get 241.
Include the next digit (1) from the dividend after 241, then repeat: 2411 / 841

Let's proceed to step 8:
841 goes into 2411 2 times with a remainder of 729.
The number 2 becomes the next digit in our result. 
Result so far: 51312.0
Subtract 1682 from 2411 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Step 9:
841 goes into 7290 8 times with a remainder of 562.
The next digit of our result is 8. 
Result so far: 51312.8
Subtract 6728 from 7290 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 10:
841 can be fit into 5620 6 times, resulting in a remainder of 574.
Record the quotient 6 as the next digit in the result. 
Result so far: 51312.86
Deduct 5046 from 5620 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 11:
If we divide 5740 by 841, we get 6 and a remainder of 694.
Put 6 as the next digit of the answer. 
Result so far: 51312.866
Subtracting 5046 from 5740 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

The final result is 51312.866 with a remainder of 0.0694.
