68516081 ÷ 138 
We're looking to find how many times 138 goes into 68516081.

On to step 1:
6 divided by 138 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 138

Advancing to step 2:
The number 138 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 138

Going ahead to step 3:
138 can be fit into 685 4 times, resulting in a remainder of 133.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 552 from 685 and we're left with 133.
Include the next digit (1) from the dividend after 133, then repeat: 1331 / 138

Step 4:
1331 divided by 138 is 9 with a remainder of 89.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 1242 from 1331 leaves us with 89.
Append the next digit (6) from the dividend to 89 and continue with: 896 / 138

Moving on to step 5:
138 can be fit into 896 6 times, resulting in a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 496.0
Subtracting 828 from 896 leaves us with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 138

Advancing to step 6:
680 divided by 138 is 4 with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 4964.0
If we take 552 away from 680, we end up with 128.
Take the next digit (8) from the dividend and append it to 128, then repeat: 1288 / 138

Let's proceed to step 7:
1288 divided by 138 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 49649.0
Subtracting 1242 from 1288 leaves us with 46.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 138

Going ahead to step 8:
When dividing 461 by 138, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 496493.0
If we subtract 414 from 461, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
138 goes into 470 3 times with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 496493.3
Subtract 414 from 470 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
If we divide 560 by 138, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 496493.34
The remainder is 8 after subtracting 552 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
The number 138 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 496493.34
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
800 divided by 138 is 5 with a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 496493.3405
Deduct 690 from 800 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
The number 138 fits into 1100 7 times, leaving a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 496493.34057
If we subtract 966 from 1100, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 14:
138 can be fit into 1340 9 times, resulting in a remainder of 98.
The next digit of our result is 9. 
Result so far: 496493.340579
Subtracting 1242 from 1340 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 15:
When dividing 980 by 138, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 496493.3405797
The remainder is 14 after subtracting 966 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 16:
138 can be fit into 140 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 496493.34057971
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 496493.34057971, and the remainder is 2e-09.
