We divide 402543 by 55
We want to divide 402543 by 55.

Step 1:
4 divided by 55 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 55

On to step 2:
The number 55 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 55

Let's proceed to step 3:
55 can be fit into 402 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 385 from 402 and we're left with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 55

On to step 4:
55 goes into 175 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 165 from 175, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 55

Advancing to step 5:
55 goes into 104 1 times with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 731.0
Subtract 55 from 104 to get 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 55

Advancing to step 6:
55 goes into 493 8 times with a remainder of 53.
The next digit of our result is 8. 
Result so far: 7318.0
Subtracting 440 from 493 leaves us with 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 7:
530 divided by 55 is 9 with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 7318.9
If we take 495 away from 530, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
350 divided by 55 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 7318.96
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 55, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 7318.963
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 7318.9636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 55 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 7318.96363
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 7318.963636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 55 is 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 7318.9636363
Deduct 165 from 200 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 14:
55 goes into 350 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 7318.96363636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 7318.96363636 with a balance of 2e-08.
