67938440 ÷ 55 
Our goal is to divide 67938440 by 55.

Step 1:
If we divide 6 by 55, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 55

Advancing to step 2:
When dividing 67 by 55, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 55 from 67, we get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 55

Going ahead to step 3:
55 goes into 129 2 times with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 19 after subtracting 110 from 129.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 55

Step 4:
The number 55 fits into 193 3 times, leaving a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Subtract 165 from 193 to get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 55

Going ahead to step 5:
55 can be fit into 288 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 1235.0
Deduct 275 from 288 and we're left with 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 55

Step 6:
If we divide 134 by 55, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 12352.0
If we take 110 away from 134, we end up with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 55

Let's proceed to step 7:
When dividing 244 by 55, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 123524.0
Subtracting 220 from 244 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 55

Advancing to step 8:
240 divided by 55 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1235244.0
Deduct 220 from 240 and we're left 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.

Let's proceed to step 9:
55 goes into 200 3 times with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 1235244.3
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.

Moving on to step 10:
When dividing 350 by 55, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 1235244.36
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.

Step 11:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 1235244.363
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.

Going ahead to step 12:
If we divide 350 by 55, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 1235244.3636
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.

Going ahead 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: 1235244.36363
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.

Moving on to step 14:
350 divided by 55 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 1235244.363636
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.

Going ahead to step 15:
55 can be fit into 200 3 times, resulting in a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 1235244.3636363
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.

Moving on to step 16:
The number 55 fits into 350 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 1235244.36363636
Deduct 330 from 350 and we're left 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.

The final outcome is 1235244.36363636, with a leftover of 2e-08.
