We're dividing 100224 by 77 
We want to figure out the number of times 100224 can be divided by 77.

On to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 77

Going ahead to step 2:
The number 77 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 77

Moving on to step 3:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 77 away from 100, we end up with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 77

Moving on to step 4:
77 can be fit into 232 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 231 from 232, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 77

Going ahead to step 5:
12 divided by 77 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 77

Step 6:
77 can be fit into 124 1 times, resulting in a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1301.0
If we subtract 77 from 124, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
77 can be fit into 470 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1301.6
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
80 divided by 77 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1301.61
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1301.61
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
If we divide 300 by 77, we get 3 and a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 1301.6103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
77 can be fit into 690 8 times, resulting in a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 1301.61038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 12:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 1301.610389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 13:
If we divide 470 by 77, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1301.6103896
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
77 can be fit into 80 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1301.61038961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 1301.61038961 with a remainder of 3e-09.
