We look at the division of 672121 by 77 
Our goal is to divide 672121 by 77.

Moving on to step 1:
77 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 77

On to step 2:
If we divide 67 by 77, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 77

Going ahead to step 3:
77 can be fit into 672 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 616 away from 672, we end up with 56.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 77

Step 4:
The number 77 fits into 561 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we subtract 539 from 561, we get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 77

Moving on to step 5:
222 divided by 77 is 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 872.0
If we take 154 away from 222, we end up with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 77

Going ahead to step 6:
When dividing 681 by 77, we get 8 with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 8728.0
If we subtract 616 from 681, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
The number 77 fits into 650 8 times, leaving a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8728.8
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
340 divided by 77 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 8728.84
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
77 can be fit into 320 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8728.844
The remainder is 12 after subtracting 308 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8728.844 with a remaining 0.0012.
