We're dividing 426643 by 33 
Our goal is to divide 426643 by 33.

On to step 1:
33 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 33

Going ahead to step 2:
33 can be fit into 42 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 9 after subtracting 33 from 42.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 33

Moving on to step 3:
If we divide 96 by 33, we get 2 and a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 66 away from 96, we end up with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 33

On to step 4:
33 can be fit into 306 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 129.0
Subtracting 297 from 306 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 33

Let's proceed to step 5:
The number 33 fits into 94 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 1292.0
Deduct 66 from 94 and we're left with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 33

Moving on to step 6:
If we divide 283 by 33, we get 8 and a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 12928.0
The remainder is 19 after subtracting 264 from 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
33 can be fit into 190 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12928.5
If we subtract 165 from 190, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
33 goes into 250 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 12928.57
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
33 can be fit into 190 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 12928.575
Subtracting 165 from 190 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
The number 33 fits into 250 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 12928.5757
Subtract 231 from 250 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
190 divided by 33 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12928.57575
Deduct 165 from 190 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
The number 33 fits into 250 7 times, leaving a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 12928.575757
The remainder is 19 after subtracting 231 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
33 can be fit into 190 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 12928.5757575
Subtracting 165 from 190 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
33 can be fit into 250 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 12928.57575757
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 12928.57575757, with a leftover of 1.9e-08.
