138122 ÷ 77 
Our goal is to divide 138122 by 77.

On to step 1:
1 divided by 77 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 77

Going ahead to step 2:
When dividing 13 by 77, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 77

Going ahead to step 3:
The number 77 fits into 138 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 138 to get 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 77

Advancing to step 4:
If we divide 611 by 77, we get 7 and a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 539 away from 611, we end up with 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 77

Let's proceed to step 5:
77 goes into 722 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 179.0
If we subtract 693 from 722, we get 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 77

Let's proceed to step 6:
292 divided by 77 is 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 1793.0
If we subtract 231 from 292, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
610 divided by 77 is 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 1793.7
If we take 539 away from 610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 8:
If we divide 710 by 77, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1793.79
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
When dividing 170 by 77, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 1793.792
If we take 154 away from 170, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 77 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 1793.7922
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 1793.7922 and a remainder of 6e-05.
