We look at the division of 12957 by 29 
Let's see how many times 29 fits into 12957.

Moving on to step 1:
29 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 29

Advancing to step 2:
29 can be fit into 12 0 times, resulting in 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.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 29

Let's proceed to step 3:
The number 29 fits into 129 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 116 from 129 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 29

Step 4:
135 divided by 29 is 4 with a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 116 away from 135, we end up with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 29

Advancing to step 5:
197 divided by 29 is 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 446.0
If we take 174 away from 197, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 6:
When dividing 230 by 29, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 446.7
Subtracting 203 from 230 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 29, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 446.79
Subtracting 261 from 270 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
The number 29 fits into 90 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 446.793
Subtracting 87 from 90 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 29, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 446.7931
The remainder is 1 after subtracting 29 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
10 divided by 29 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 446.7931
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 29, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 446.793103
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
29 can be fit into 130 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 446.7931034
Subtracting 116 from 130 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
If we divide 140 by 29, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 446.79310344
If we subtract 116 from 140, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 446.79310344, and the remainder is 2.4e-08.
