64454399 ÷ 779 
We want to figure out the number of times 64454399 can be divided by 779.

Let's proceed to step 1:
When dividing 6 by 779, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 779

Going ahead to step 2:
If we divide 64 by 779, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 779

Moving on to step 3:
644 divided by 779 is 0 with a remainder of 644.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 644, we get 644.
Take the next digit (5) from the dividend and append it to 644, then repeat: 6445 / 779

Advancing to step 4:
779 can be fit into 6445 8 times, resulting in a remainder of 213.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 6232 from 6445 leaves us with 213.
Fetch the next digit (4) from the dividend, attach it to 213 and continue: 2134 / 779

Let's proceed to step 5:
779 goes into 2134 2 times with a remainder of 576.
The next digit of our result is 2. 
Result so far: 82.0
Deduct 1558 from 2134 and we're left with 576.
Include the next digit (3) from the dividend after 576, then repeat: 5763 / 779

Step 6:
779 goes into 5763 7 times with a remainder of 310.
Write down 7 as next digit of the result. 
Result so far: 827.0
If we take 5453 away from 5763, we end up with 310.
Fetch the next digit (9) from the dividend, attach it to 310 and continue: 3109 / 779

Step 7:
779 goes into 3109 3 times with a remainder of 772.
Use 3 as the next digit of our solution. 
Result so far: 8273.0
Deduct 2337 from 3109 and we're left with 772.
Append the next digit (9) from the dividend to 772 and continue with: 7729 / 779

Step 8:
7729 divided by 779 is 9 with a remainder of 718.
Record the quotient 9 as the next digit in the result. 
Result so far: 82739.0
If we subtract 7011 from 7729, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Let's proceed to step 9:
779 goes into 7180 9 times with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 82739.9
Subtract 7011 from 7180 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 10:
779 goes into 1690 2 times with a remainder of 132.
Write down 2 as next digit of the result. 
Result so far: 82739.92
Deduct 1558 from 1690 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
If we divide 1320 by 779, we get 1 and a remainder of 541.
Write down 1 as next digit of the result. 
Result so far: 82739.921
Deduct 779 from 1320 and we're left with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Advancing to step 12:
779 goes into 5410 6 times with a remainder of 736.
Record the quotient 6 as the next digit in the result. 
Result so far: 82739.9216
The remainder is 736 after subtracting 4674 from 5410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 13:
The number 779 fits into 7360 9 times, leaving a remainder of 349.
Write down 9 as next digit of the result. 
Result so far: 82739.92169
Subtract 7011 from 7360 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Let's proceed to step 14:
When dividing 3490 by 779, we get 4 with a remainder of 374.
Record the quotient 4 as the next digit in the result. 
Result so far: 82739.921694
If we take 3116 away from 3490, we end up with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 15:
779 goes into 3740 4 times with a remainder of 624.
The number 4 becomes the next digit in our result. 
Result so far: 82739.9216944
The remainder is 624 after subtracting 3116 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The quotient of the division is 82739.9216944, and the remainder is 6.24e-06.
