We're dividing 68419608 by 138 
Let's see how many times 138 fits into 68419608.

Step 1:
When dividing 6 by 138, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 138

Moving on to step 2:
When dividing 68 by 138, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 138

Going ahead to step 3:
684 divided by 138 is 4 with a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 552 from 684 and we're left with 132.
Grab the next digit (1) from the dividend, add it to 132, then carry on: 1321 / 138

Going ahead to step 4:
The number 138 fits into 1321 9 times, leaving a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 1242 from 1321, we get 79.
Append the next digit (9) from the dividend to 79 and continue with: 799 / 138

Step 5:
When dividing 799 by 138, we get 5 with a remainder of 109.
Use 5 as the next digit of our solution. 
Result so far: 495.0
If we subtract 690 from 799, we get 109.
Take the next digit (6) from the dividend and append it to 109, then repeat: 1096 / 138

Let's proceed to step 6:
The number 138 fits into 1096 7 times, leaving a remainder of 130.
The number 7 becomes the next digit in our result. 
Result so far: 4957.0
Subtract 966 from 1096 to get 130.
Include the next digit (0) from the dividend after 130, then repeat: 1300 / 138

Advancing to step 7:
1300 divided by 138 is 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 49579.0
Subtract 1242 from 1300 to get 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 138

On to step 8:
138 can be fit into 588 4 times, resulting in a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 495794.0
Subtracting 552 from 588 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 138 is 2 with a remainder of 84.
The next digit of our result is 2. 
Result so far: 495794.2
Subtract 276 from 360 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 10:
If we divide 840 by 138, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 495794.26
Subtract 828 from 840 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
138 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 495794.26
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 138 is 8 with a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 495794.2608
If we subtract 1104 from 1200, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
960 divided by 138 is 6 with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 495794.26086
If we subtract 828 from 960, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
If we divide 1320 by 138, we get 9 and a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 495794.260869
Deduct 1242 from 1320 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 15:
When dividing 780 by 138, we get 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 495794.2608695
If we take 690 away from 780, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 16:
138 can be fit into 900 6 times, resulting in a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 495794.26086956
Subtracting 828 from 900 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 495794.26086956 with a remaining 7.2e-08.
