63146966 divided by 770 
We want to figure out the number of times 63146966 can be divided by 770.

Going ahead to step 1:
If we divide 6 by 770, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 770

On to step 2:
When dividing 63 by 770, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 770

On to step 3:
When dividing 631 by 770, we get 0 with a remainder of 631.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 631 to get 631.
Bring next digit (4) of the dividend behind the 631 and repeat the process: 6314 / 770

Advancing to step 4:
770 goes into 6314 8 times with a remainder of 154.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 6160 away from 6314, we end up with 154.
Bring next digit (6) of the dividend behind the 154 and repeat the process: 1546 / 770

Step 5:
770 goes into 1546 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtract 1540 from 1546 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 770

On to step 6:
770 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we subtract 0 from 69, we get 69.
Take the next digit (6) from the dividend and append it to 69, then repeat: 696 / 770

Going ahead to step 7:
696 divided by 770 is 0 with a remainder of 696.
Use 0 as the next digit of our solution. 
Result so far: 8200.0
Subtracting 0 from 696 leaves us with 696.
Include the next digit (6) from the dividend after 696, then repeat: 6966 / 770

On to step 8:
The number 770 fits into 6966 9 times, leaving a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 82009.0
Subtracting 6930 from 6966 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
The number 770 fits into 360 0 times, leaving a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 82009.0
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 10:
The number 770 fits into 3600 4 times, leaving a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 82009.04
Subtract 3080 from 3600 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 11:
5200 divided by 770 is 6 with a remainder of 580.
The number 6 becomes the next digit in our result. 
Result so far: 82009.046
The remainder is 580 after subtracting 4620 from 5200.
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 12:
770 can be fit into 5800 7 times, resulting in a remainder of 410.
Use 7 as the next digit of our solution. 
Result so far: 82009.0467
The remainder is 410 after subtracting 5390 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 13:
770 can be fit into 4100 5 times, resulting in a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 82009.04675
The remainder is 250 after subtracting 3850 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 14:
If we divide 2500 by 770, we get 3 and a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 82009.046753
The remainder is 190 after subtracting 2310 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 15:
The number 770 fits into 1900 2 times, leaving a remainder of 360.
The next digit of our result is 2. 
Result so far: 82009.0467532
Subtract 1540 from 1900 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 16:
770 goes into 3600 4 times with a remainder of 520.
The next digit of our result is 4. 
Result so far: 82009.04675324
If we subtract 3080 from 3600, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final outcome is 82009.04675324, with a leftover of 5.2e-07.
