We divide 415212 by 34
We want to figure out the number of times 415212 can be divided by 34.

On to step 1:
The number 34 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 34

Moving on to step 2:
34 can be fit into 41 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 34 from 41 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 34

Moving on to step 3:
34 goes into 75 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 68 away from 75, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 34

On to step 4:
34 can be fit into 72 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we take 68 away from 72, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 34

On to step 5:
The number 34 fits into 41 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1221.0
Subtracting 34 from 41 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 34

Advancing to step 6:
34 goes into 72 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12212.0
The remainder is 4 after subtracting 68 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
34 goes into 40 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 12212.1
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 34 is 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 12212.11
If we take 34 away from 60, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 12212.11 with a remainder of 0.026.
