Let's divide 4230 by 55
Our goal is to divide 4230 by 55.

Going ahead to step 1:
The number 55 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.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 55

On to step 2:
55 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 55

Step 3:
423 divided by 55 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 385 away from 423, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 55

Moving on to step 4:
55 goes into 380 6 times with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 5:
When dividing 500 by 55, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 76.9
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
55 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 76.9
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
The number 55 fits into 500 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 76.909
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 55, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 76.909
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
When dividing 500 by 55, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 76.90909
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
50 divided by 55 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 76.90909
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 76.9090909
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 76.9090909
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 76.9090909, with a leftover of 5e-08.
