We look at the division of 29643942 by 431 
We're looking to find how many times 431 goes into 29643942.

On to step 1:
If we divide 2 by 431, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 431

On to step 2:
431 goes into 29 0 times with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 431

Moving on to step 3:
When dividing 296 by 431, we get 0 with a remainder of 296.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 296 and we're left with 296.
Include the next digit (4) from the dividend after 296, then repeat: 2964 / 431

Let's proceed to step 4:
431 can be fit into 2964 6 times, resulting in a remainder of 378.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 2586 from 2964 to get 378.
Take the next digit (3) from the dividend and append it to 378, then repeat: 3783 / 431

Advancing to step 5:
431 can be fit into 3783 8 times, resulting in a remainder of 335.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtract 3448 from 3783 to get 335.
Append the next digit (9) from the dividend to 335 and continue with: 3359 / 431

Going ahead to step 6:
3359 divided by 431 is 7 with a remainder of 342.
Put 7 as the next digit of the answer. 
Result so far: 687.0
Deduct 3017 from 3359 and we're left with 342.
Include the next digit (4) from the dividend after 342, then repeat: 3424 / 431

Moving on to step 7:
The number 431 fits into 3424 7 times, leaving a remainder of 407.
The next digit of our result is 7. 
Result so far: 6877.0
Subtracting 3017 from 3424 leaves us with 407.
Include the next digit (2) from the dividend after 407, then repeat: 4072 / 431

Moving on to step 8:
If we divide 4072 by 431, we get 9 and a remainder of 193.
Record the quotient 9 as the next digit in the result. 
Result so far: 68779.0
Deduct 3879 from 4072 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 9:
431 can be fit into 1930 4 times, resulting in a remainder of 206.
Put 4 as the next digit of the answer. 
Result so far: 68779.4
Deduct 1724 from 1930 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 10:
431 goes into 2060 4 times with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 68779.44
If we subtract 1724 from 2060, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 68779.44, with a leftover of 0.336.
