39524381 ÷ 778 
Let's see how many times 778 fits into 39524381.

Step 1:
When dividing 3 by 778, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 778

Let's proceed to step 2:
39 divided by 778 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 778

Going ahead to step 3:
The number 778 fits into 395 0 times, leaving a remainder of 395.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 395, we get 395.
Fetch the next digit (2) from the dividend, attach it to 395 and continue: 3952 / 778

Moving on to step 4:
778 can be fit into 3952 5 times, resulting in a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3890 from 3952, we get 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 778

On to step 5:
624 divided by 778 is 0 with a remainder of 624.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 624 leaves us with 624.
Bring next digit (3) of the dividend behind the 624 and repeat the process: 6243 / 778

Going ahead to step 6:
The number 778 fits into 6243 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 508.0
Deduct 6224 from 6243 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 778

Let's proceed to step 7:
778 goes into 198 0 times with a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 5080.0
Deduct 0 from 198 and we're left with 198.
Fetch the next digit (1) from the dividend, attach it to 198 and continue: 1981 / 778

Step 8:
1981 divided by 778 is 2 with a remainder of 425.
Use 2 as the next digit of our solution. 
Result so far: 50802.0
Subtracting 1556 from 1981 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 9:
The number 778 fits into 4250 5 times, leaving a remainder of 360.
Put 5 as the next digit of the answer. 
Result so far: 50802.5
If we take 3890 away from 4250, we end up 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.

Advancing to step 10:
778 goes into 3600 4 times with a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 50802.54
Deduct 3112 from 3600 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 11:
If we divide 4880 by 778, we get 6 and a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 50802.546
Deduct 4668 from 4880 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 12:
When dividing 2120 by 778, we get 2 with a remainder of 564.
Write down 2 as next digit of the result. 
Result so far: 50802.5462
If we subtract 1556 from 2120, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 13:
If we divide 5640 by 778, we get 7 and a remainder of 194.
Use 7 as the next digit of our solution. 
Result so far: 50802.54627
Subtracting 5446 from 5640 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 14:
1940 divided by 778 is 2 with a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 50802.546272
Deduct 1556 from 1940 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 15:
778 goes into 3840 4 times with a remainder of 728.
Record the quotient 4 as the next digit in the result. 
Result so far: 50802.5462724
The remainder is 728 after subtracting 3112 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 16:
If we divide 7280 by 778, we get 9 and a remainder of 278.
The next digit of our result is 9. 
Result so far: 50802.54627249
Subtract 7002 from 7280 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

The final result is 50802.54627249 with a remainder of 2.78e-07.
