Let's divide 121777 by 8
We're looking to find how many times 8 goes into 121777.

Step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 8

Advancing to step 2:
8 can be fit into 12 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 8 from 12 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 8

On to step 3:
8 goes into 41 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 40 away from 41, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 8

Step 4:
8 goes into 17 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 16 from 17 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 8

On to step 5:
8 goes into 17 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 1522.0
Subtracting 16 from 17 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 8

On to step 6:
When dividing 17 by 8, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 15222.0
Subtracting 16 from 17 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 8 fits into 10 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 15222.1
If we take 8 away from 10, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
When dividing 20 by 8, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 15222.12
If we subtract 16 from 20, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
8 goes into 40 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 15222.125
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15222.125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15222.125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 15222.125 with a remaining 0.0.
