39649857 ÷ 773 
We want to figure out the number of times 39649857 can be divided by 773.

Moving on to step 1:
773 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 773

Advancing to step 2:
When dividing 39 by 773, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 773

Going ahead to step 3:
773 can be fit into 396 0 times, resulting in a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.
Fetch the next digit (4) from the dividend, attach it to 396 and continue: 3964 / 773

Going ahead to step 4:
The number 773 fits into 3964 5 times, leaving a remainder of 99.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 3865 from 3964 leaves us with 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 773

Going ahead to step 5:
The number 773 fits into 999 1 times, leaving a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 773 from 999 leaves us with 226.
Grab the next digit (8) from the dividend, add it to 226, then carry on: 2268 / 773

Step 6:
773 goes into 2268 2 times with a remainder of 722.
Write down 2 as next digit of the result. 
Result so far: 512.0
Subtracting 1546 from 2268 leaves us with 722.
Grab the next digit (5) from the dividend, add it to 722, then carry on: 7225 / 773

Going ahead to step 7:
When dividing 7225 by 773, we get 9 with a remainder of 268.
Put 9 as the next digit of the answer. 
Result so far: 5129.0
If we subtract 6957 from 7225, we get 268.
Include the next digit (7) from the dividend after 268, then repeat: 2687 / 773

On to step 8:
When dividing 2687 by 773, we get 3 with a remainder of 368.
Use 3 as the next digit of our solution. 
Result so far: 51293.0
Subtract 2319 from 2687 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 9:
The number 773 fits into 3680 4 times, leaving a remainder of 588.
Record the quotient 4 as the next digit in the result. 
Result so far: 51293.4
The remainder is 588 after subtracting 3092 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 10:
The number 773 fits into 5880 7 times, leaving a remainder of 469.
Record the quotient 7 as the next digit in the result. 
Result so far: 51293.47
Subtract 5411 from 5880 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 11:
773 can be fit into 4690 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 51293.476
Deduct 4638 from 4690 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
The number 773 fits into 520 0 times, leaving a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 51293.476
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 13:
The number 773 fits into 5200 6 times, leaving a remainder of 562.
The number 6 becomes the next digit in our result. 
Result so far: 51293.47606
Deduct 4638 from 5200 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 14:
When dividing 5620 by 773, we get 7 with a remainder of 209.
Use 7 as the next digit of our solution. 
Result so far: 51293.476067
If we subtract 5411 from 5620, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 15:
2090 divided by 773 is 2 with a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 51293.4760672
The remainder is 544 after subtracting 1546 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 16:
If we divide 5440 by 773, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 51293.47606727
If we subtract 5411 from 5440, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 51293.47606727 with a remaining 2.9e-08.
