We look at the division of 77926688 by 138 
We're looking to find how many times 138 goes into 77926688.

Moving on to step 1:
138 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 138

Moving on to step 2:
When dividing 77 by 138, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 138

Going ahead to step 3:
138 can be fit into 779 5 times, resulting in a remainder of 89.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 690 from 779 to get 89.
Take the next digit (2) from the dividend and append it to 89, then repeat: 892 / 138

Advancing to step 4:
138 goes into 892 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 828 from 892 to get 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 138

Advancing to step 5:
646 divided by 138 is 4 with a remainder of 94.
The next digit of our result is 4. 
Result so far: 564.0
If we subtract 552 from 646, we get 94.
Include the next digit (6) from the dividend after 94, then repeat: 946 / 138

Let's proceed to step 6:
138 can be fit into 946 6 times, resulting in a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 5646.0
The remainder is 118 after subtracting 828 from 946.
Take the next digit (8) from the dividend and append it to 118, then repeat: 1188 / 138

Going ahead to step 7:
138 goes into 1188 8 times with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 56468.0
If we take 1104 away from 1188, we end up with 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 138

Going ahead to step 8:
The number 138 fits into 848 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 564686.0
Subtract 828 from 848 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 9:
138 goes into 200 1 times with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 564686.1
If we take 138 away from 200, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
138 can be fit into 620 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 564686.14
Subtracting 552 from 620 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
138 can be fit into 680 4 times, resulting in a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 564686.144
If we take 552 away from 680, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 564686.144 and a remainder of 0.0128.
