We're dividing 349915 by 4 
We want to divide 349915 by 4.

Let's proceed to step 1:
If we divide 3 by 4, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

On to step 2:
4 goes into 34 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 32 from 34 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

Advancing to step 3:
The number 4 fits into 29 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 28 away from 29, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 4

Going ahead to step 4:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 874.0
Subtract 16 from 19 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 4

Let's proceed to step 5:
4 can be fit into 31 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 8747.0
If we subtract 28 from 31, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 4

Advancing to step 6:
35 divided by 4 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 87478.0
If we take 32 away from 35, 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 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 87478.7
If we take 28 away from 30, we end up 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.

Advancing to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 87478.75
Subtract 20 from 20 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.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 87478.75
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.

Let's proceed to step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 87478.75
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.

After the division, we end up with 87478.75 and a remainder of 0.0.
