63458144 ÷ 779 
Let's see how many times 779 fits into 63458144.

Going ahead to step 1:
The number 779 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 779

Advancing to step 2:
779 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 779

Step 3:
779 goes into 634 0 times with a remainder of 634.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 634 after subtracting 0 from 634.
Fetch the next digit (5) from the dividend, attach it to 634 and continue: 6345 / 779

Step 4:
The number 779 fits into 6345 8 times, leaving a remainder of 113.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 6232 from 6345, we get 113.
Append the next digit (8) from the dividend to 113 and continue with: 1138 / 779

Moving on to step 5:
779 can be fit into 1138 1 times, resulting in a remainder of 359.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 359 after subtracting 779 from 1138.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 779

Going ahead to step 6:
779 goes into 3591 4 times with a remainder of 475.
The next digit of our result is 4. 
Result so far: 814.0
Subtracting 3116 from 3591 leaves us with 475.
Take the next digit (4) from the dividend and append it to 475, then repeat: 4754 / 779

Going ahead to step 7:
When dividing 4754 by 779, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 8146.0
If we subtract 4674 from 4754, we get 80.
Take the next digit (4) from the dividend and append it to 80, then repeat: 804 / 779

Step 8:
779 goes into 804 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 81461.0
Deduct 779 from 804 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
779 can be fit into 250 0 times, resulting in a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 81461.0
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 10:
If we divide 2500 by 779, we get 3 and a remainder of 163.
The next digit of our result is 3. 
Result so far: 81461.03
If we take 2337 away from 2500, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 11:
1630 divided by 779 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 81461.032
Subtracting 1558 from 1630 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
The number 779 fits into 720 0 times, leaving a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 81461.032
Subtracting 0 from 720 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 13:
7200 divided by 779 is 9 with a remainder of 189.
Record the quotient 9 as the next digit in the result. 
Result so far: 81461.03209
Deduct 7011 from 7200 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Moving on to step 14:
If we divide 1890 by 779, we get 2 and a remainder of 332.
The number 2 becomes the next digit in our result. 
Result so far: 81461.032092
Deduct 1558 from 1890 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 15:
3320 divided by 779 is 4 with a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 81461.0320924
The remainder is 204 after subtracting 3116 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 16:
779 can be fit into 2040 2 times, resulting in a remainder of 482.
The number 2 becomes the next digit in our result. 
Result so far: 81461.03209242
If we take 1558 away from 2040, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

After the division, we end up with 81461.03209242 and a remainder of 4.82e-07.
