Let's divide 288221 by 77
We want to figure out the number of times 288221 can be divided by 77.

Advancing to step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 77

Let's proceed to step 2:
When dividing 28 by 77, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 77

Advancing to step 3:
When dividing 288 by 77, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 231 from 288 to get 57.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 77

Going ahead to step 4:
572 divided by 77 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we take 539 away from 572, we end up with 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 77

Step 5:
77 can be fit into 332 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 374.0
Deduct 308 from 332 and we're left with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 77

Moving on to step 6:
When dividing 241 by 77, we get 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3743.0
Subtracting 231 from 241 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 3743.1
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 8:
When dividing 230 by 77, we get 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 3743.12
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
77 goes into 760 9 times with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 3743.129
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
77 goes into 670 8 times with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 3743.1298
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
540 divided by 77 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 3743.12987
Subtract 539 from 540 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3743.12987
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 77 fits into 100 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 3743.1298701
Subtract 77 from 100 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 14:
When dividing 230 by 77, we get 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 3743.12987012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

After the division, we end up with 3743.12987012 and a remainder of 7.6e-08.
