We look at the division of 40869429 by 4 
We're looking to find how many times 4 goes into 40869429.

On to step 1:
4 can be fit into 4 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 4

Step 2:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 0 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 4

Moving on to step 3:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 8 from 8 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

Step 4:
When dividing 6 by 4, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1021.0
If we subtract 4 from 6, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 4

On to step 5:
If we divide 29 by 4, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 10217.0
Subtracting 28 from 29 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 4

Advancing to step 6:
When dividing 14 by 4, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 102173.0
Subtracting 12 from 14 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 4

Let's proceed to step 7:
When dividing 22 by 4, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 1021735.0
Subtract 20 from 22 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 4

On to step 8:
4 goes into 29 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 10217357.0
Subtract 28 from 29 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.

Going ahead to step 9:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 10217357.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 4 fits into 20 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10217357.25
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10217357.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10217357.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10217357.25, with a leftover of 0.0.
