64963806 ÷ 669 
We want to divide 64963806 by 669.

Moving on to step 1:
669 can be fit into 6 0 times, resulting in 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 (4) from the dividend to 6 and continue with: 64 / 669

On to step 2:
The number 669 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 669

Moving on to step 3:
649 divided by 669 is 0 with a remainder of 649.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 649, we get 649.
Include the next digit (6) from the dividend after 649, then repeat: 6496 / 669

Step 4:
The number 669 fits into 6496 9 times, leaving a remainder of 475.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 6021 away from 6496, we end up with 475.
Include the next digit (3) from the dividend after 475, then repeat: 4753 / 669

Advancing to step 5:
4753 divided by 669 is 7 with a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtracting 4683 from 4753 leaves us with 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 669

Moving on to step 6:
When dividing 708 by 669, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 971.0
The remainder is 39 after subtracting 669 from 708.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 669

Let's proceed to step 7:
The number 669 fits into 390 0 times, leaving a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 9710.0
If we subtract 0 from 390, we get 390.
Append the next digit (6) from the dividend to 390 and continue with: 3906 / 669

Step 8:
If we divide 3906 by 669, we get 5 and a remainder of 561.
Write down 5 as next digit of the result. 
Result so far: 97105.0
If we take 3345 away from 3906, we end up with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 9:
669 goes into 5610 8 times with a remainder of 258.
Put 8 as the next digit of the answer. 
Result so far: 97105.8
The remainder is 258 after subtracting 5352 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
When dividing 2580 by 669, we get 3 with a remainder of 573.
The number 3 becomes the next digit in our result. 
Result so far: 97105.83
If we subtract 2007 from 2580, we get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 11:
When dividing 5730 by 669, we get 8 with a remainder of 378.
Write down 8 as next digit of the result. 
Result so far: 97105.838
The remainder is 378 after subtracting 5352 from 5730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 12:
The number 669 fits into 3780 5 times, leaving a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 97105.8385
If we subtract 3345 from 3780, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 13:
When dividing 4350 by 669, we get 6 with a remainder of 336.
The next digit of our result is 6. 
Result so far: 97105.83856
Deduct 4014 from 4350 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 14:
669 goes into 3360 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 97105.838565
The remainder is 15 after subtracting 3345 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 15:
The number 669 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 97105.838565
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 16:
1500 divided by 669 is 2 with a remainder of 162.
Write down 2 as next digit of the result. 
Result so far: 97105.83856502
Subtract 1338 from 1500 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 97105.83856502, with a leftover of 1.62e-07.
