We're dividing 77793466 by 630 
We want to figure out the number of times 77793466 can be divided by 630.

Advancing to step 1:
The number 630 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 630

Advancing to step 2:
If we divide 77 by 630, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 630

Step 3:
The number 630 fits into 777 1 times, leaving a remainder of 147.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 630 from 777 to get 147.
Include the next digit (9) from the dividend after 147, then repeat: 1479 / 630

Step 4:
1479 divided by 630 is 2 with a remainder of 219.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1260 from 1479 and we're left with 219.
Append the next digit (3) from the dividend to 219 and continue with: 2193 / 630

Step 5:
630 goes into 2193 3 times with a remainder of 303.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Deduct 1890 from 2193 and we're left with 303.
Take the next digit (4) from the dividend and append it to 303, then repeat: 3034 / 630

Let's proceed to step 6:
630 goes into 3034 4 times with a remainder of 514.
Use 4 as the next digit of our solution. 
Result so far: 1234.0
The remainder is 514 after subtracting 2520 from 3034.
Append the next digit (6) from the dividend to 514 and continue with: 5146 / 630

On to step 7:
630 goes into 5146 8 times with a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 12348.0
The remainder is 106 after subtracting 5040 from 5146.
Grab the next digit (6) from the dividend, add it to 106, then carry on: 1066 / 630

Step 8:
630 can be fit into 1066 1 times, resulting in a remainder of 436.
The number 1 becomes the next digit in our result. 
Result so far: 123481.0
If we subtract 630 from 1066, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 9:
4360 divided by 630 is 6 with a remainder of 580.
The next digit of our result is 6. 
Result so far: 123481.6
If we subtract 3780 from 4360, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 10:
If we divide 5800 by 630, we get 9 and a remainder of 130.
Write down 9 as next digit of the result. 
Result so far: 123481.69
Deduct 5670 from 5800 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
If we divide 1300 by 630, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 123481.692
Subtract 1260 from 1300 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
630 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 123481.692
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
630 can be fit into 4000 6 times, resulting in a remainder of 220.
Put 6 as the next digit of the answer. 
Result so far: 123481.69206
If we subtract 3780 from 4000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 14:
If we divide 2200 by 630, we get 3 and a remainder of 310.
The next digit of our result is 3. 
Result so far: 123481.692063
The remainder is 310 after subtracting 1890 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 15:
The number 630 fits into 3100 4 times, leaving a remainder of 580.
The number 4 becomes the next digit in our result. 
Result so far: 123481.6920634
If we take 2520 away from 3100, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 16:
630 goes into 5800 9 times with a remainder of 130.
Put 9 as the next digit of the answer. 
Result so far: 123481.69206349
If we subtract 5670 from 5800, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 123481.69206349, and the remainder is 1.3e-07.
