We're dividing 77489699 by 312 
We're looking to find how many times 312 goes into 77489699.

On to step 1:
312 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 312

Advancing to step 2:
77 divided by 312 is 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 312

Going ahead to step 3:
312 can be fit into 774 2 times, resulting in a remainder of 150.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 624 away from 774, we end up with 150.
Bring next digit (8) of the dividend behind the 150 and repeat the process: 1508 / 312

Step 4:
312 can be fit into 1508 4 times, resulting in a remainder of 260.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 1248 from 1508 to get 260.
Include the next digit (9) from the dividend after 260, then repeat: 2609 / 312

Let's proceed to step 5:
When dividing 2609 by 312, we get 8 with a remainder of 113.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
If we subtract 2496 from 2609, we get 113.
Include the next digit (6) from the dividend after 113, then repeat: 1136 / 312

Let's proceed to step 6:
The number 312 fits into 1136 3 times, leaving a remainder of 200.
The next digit of our result is 3. 
Result so far: 2483.0
Subtracting 936 from 1136 leaves us with 200.
Include the next digit (9) from the dividend after 200, then repeat: 2009 / 312

On to step 7:
The number 312 fits into 2009 6 times, leaving a remainder of 137.
Record the quotient 6 as the next digit in the result. 
Result so far: 24836.0
If we subtract 1872 from 2009, we get 137.
Bring next digit (9) of the dividend behind the 137 and repeat the process: 1379 / 312

Going ahead to step 8:
The number 312 fits into 1379 4 times, leaving a remainder of 131.
Put 4 as the next digit of the answer. 
Result so far: 248364.0
If we subtract 1248 from 1379, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
When dividing 1310 by 312, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 248364.4
If we subtract 1248 from 1310, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 10:
312 goes into 620 1 times with a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 248364.41
The remainder is 308 after subtracting 312 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
When dividing 3080 by 312, we get 9 with a remainder of 272.
Write down 9 as next digit of the result. 
Result so far: 248364.419
Deduct 2808 from 3080 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 12:
If we divide 2720 by 312, we get 8 and a remainder of 224.
Write down 8 as next digit of the result. 
Result so far: 248364.4198
If we take 2496 away from 2720, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 13:
If we divide 2240 by 312, we get 7 and a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 248364.41987
Subtracting 2184 from 2240 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
312 can be fit into 560 1 times, resulting in a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 248364.419871
The remainder is 248 after subtracting 312 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 15:
When dividing 2480 by 312, we get 7 with a remainder of 296.
Record the quotient 7 as the next digit in the result. 
Result so far: 248364.4198717
If we take 2184 away from 2480, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 16:
312 goes into 2960 9 times with a remainder of 152.
Use 9 as the next digit of our solution. 
Result so far: 248364.41987179
If we take 2808 away from 2960, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 248364.41987179 and a remainder of 1.52e-07.
