67143855 ÷ 55 
We want to figure out the number of times 67143855 can be divided by 55.

Step 1:
If we divide 6 by 55, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 55

Let's proceed to step 2:
The number 55 fits into 67 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 55 from 67 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 55

Going ahead to step 3:
If we divide 121 by 55, we get 2 and a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 110 from 121, we get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 55

Moving on to step 4:
When dividing 114 by 55, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtract 110 from 114 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 55

Advancing to step 5:
55 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 1220.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 55

Advancing to step 6:
55 goes into 438 7 times with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 12207.0
The remainder is 53 after subtracting 385 from 438.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 55

Moving on to step 7:
The number 55 fits into 535 9 times, leaving a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 122079.0
If we subtract 495 from 535, we get 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 55

Advancing to step 8:
55 can be fit into 405 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 1220797.0
Subtracting 385 from 405 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 55 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 1220797.3
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.

On to step 10:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1220797.36
Subtract 330 from 350 to 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.

Going ahead to step 11:
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: 1220797.363
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1220797.3636
Subtract 330 from 350 to 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.

Let's proceed to step 13:
200 divided by 55 is 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 1220797.36363
If we take 165 away from 200, 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.

Moving on to step 14:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1220797.363636
Subtracting 330 from 350 leaves us with 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 15:
55 goes into 200 3 times with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 1220797.3636363
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 16:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1220797.36363636
Subtract 330 from 350 to 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.

The final result is 1220797.36363636 with a remainder of 2e-08.
