We're dividing 456123 by 29 
Our goal is to divide 456123 by 29.

On to step 1:
The number 29 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 29

On to step 2:
If we divide 45 by 29, we get 1 and a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 29 away from 45, we end up with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 29

Step 3:
When dividing 166 by 29, we get 5 with a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 145 from 166 to get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 29

Step 4:
The number 29 fits into 211 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Subtracting 203 from 211 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 29

Going ahead to step 5:
The number 29 fits into 82 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1572.0
Deduct 58 from 82 and we're left with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 29

Moving on to step 6:
The number 29 fits into 243 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 15728.0
Subtract 232 from 243 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 29, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 15728.3
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
The number 29 fits into 230 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 15728.37
Subtract 203 from 230 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
The number 29 fits into 270 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 15728.379
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.

Let's proceed to step 10:
29 can be fit into 90 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 15728.3793
If we take 87 away from 90, we end up 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 11:
When dividing 30 by 29, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 15728.37931
Deduct 29 from 30 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
29 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15728.37931
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 15728.3793103
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 14:
If we divide 130 by 29, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 15728.37931034
Subtract 116 from 130 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 15728.37931034 with a remaining 1.4e-08.
