We divide 400929 by 4
We want to divide 400929 by 4.

On to step 1:
If we divide 4 by 4, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 4 from 4, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 4

Step 2:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

On to step 3:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 4

Going ahead to step 4:
4 can be fit into 9 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 1002.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 4

Moving on to step 5:
The number 4 fits into 12 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 10023.0
Subtracting 12 from 12 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 4

Going ahead to step 6:
4 can be fit into 9 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 100232.0
Subtract 8 from 9 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 4, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 100232.2
Deduct 8 from 10 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 100232.25
Subtracting 20 from 20 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 100232.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 100232.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 100232.25 with a remaining 0.0.
