We're dividing 73453228 by 427 
Let's see how many times 427 fits into 73453228.

Going ahead to step 1:
7 divided by 427 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 427

On to step 2:
73 divided by 427 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 427

Advancing to step 3:
If we divide 734 by 427, we get 1 and a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 427 from 734, we get 307.
Append the next digit (5) from the dividend to 307 and continue with: 3075 / 427

On to step 4:
427 can be fit into 3075 7 times, resulting in a remainder of 86.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 2989 from 3075 and we're left with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 427

Advancing to step 5:
When dividing 863 by 427, we get 2 with a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtract 854 from 863 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 427

Going ahead to step 6:
92 divided by 427 is 0 with a remainder of 92.
Put 0 as the next digit of the answer. 
Result so far: 1720.0
If we take 0 away from 92, we end up with 92.
Grab the next digit (2) from the dividend, add it to 92, then carry on: 922 / 427

Advancing to step 7:
If we divide 922 by 427, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 17202.0
Subtracting 854 from 922 leaves us with 68.
Include the next digit (8) from the dividend after 68, then repeat: 688 / 427

On to step 8:
688 divided by 427 is 1 with a remainder of 261.
Record the quotient 1 as the next digit in the result. 
Result so far: 172021.0
If we subtract 427 from 688, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 9:
When dividing 2610 by 427, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 172021.6
Deduct 2562 from 2610 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 427 is 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 172021.61
If we subtract 427 from 480, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
When dividing 530 by 427, we get 1 with a remainder of 103.
Put 1 as the next digit of the answer. 
Result so far: 172021.611
Subtracting 427 from 530 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

After the division, we end up with 172021.611 and a remainder of 0.0103.
