39670111 ÷ 777 
We want to figure out the number of times 39670111 can be divided by 777.

Step 1:
3 divided by 777 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 777

Advancing to step 2:
If we divide 39 by 777, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 777

Advancing to step 3:
When dividing 396 by 777, we get 0 with a remainder of 396.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 396 after subtracting 0 from 396.
Take the next digit (7) from the dividend and append it to 396, then repeat: 3967 / 777

Let's proceed to step 4:
777 can be fit into 3967 5 times, resulting in a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 3885 from 3967 to get 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 777

Moving on to step 5:
The number 777 fits into 820 1 times, leaving a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 777 from 820 and we're left with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 777

Moving on to step 6:
777 goes into 431 0 times with a remainder of 431.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Deduct 0 from 431 and we're left with 431.
Bring next digit (1) of the dividend behind the 431 and repeat the process: 4311 / 777

Going ahead to step 7:
777 goes into 4311 5 times with a remainder of 426.
Put 5 as the next digit of the answer. 
Result so far: 5105.0
Subtracting 3885 from 4311 leaves us with 426.
Include the next digit (1) from the dividend after 426, then repeat: 4261 / 777

On to step 8:
The number 777 fits into 4261 5 times, leaving a remainder of 376.
Use 5 as the next digit of our solution. 
Result so far: 51055.0
Deduct 3885 from 4261 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 9:
777 goes into 3760 4 times with a remainder of 652.
The next digit of our result is 4. 
Result so far: 51055.4
If we subtract 3108 from 3760, we get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

On to step 10:
If we divide 6520 by 777, we get 8 and a remainder of 304.
Record the quotient 8 as the next digit in the result. 
Result so far: 51055.48
Subtracting 6216 from 6520 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
When dividing 3040 by 777, we get 3 with a remainder of 709.
The next digit of our result is 3. 
Result so far: 51055.483
The remainder is 709 after subtracting 2331 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Moving on to step 12:
The number 777 fits into 7090 9 times, leaving a remainder of 97.
Put 9 as the next digit of the answer. 
Result so far: 51055.4839
If we take 6993 away from 7090, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 13:
777 goes into 970 1 times with a remainder of 193.
The next digit of our result is 1. 
Result so far: 51055.48391
If we take 777 away from 970, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 14:
777 can be fit into 1930 2 times, resulting in a remainder of 376.
The next digit of our result is 2. 
Result so far: 51055.483912
Subtracting 1554 from 1930 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 15:
When dividing 3760 by 777, we get 4 with a remainder of 652.
The number 4 becomes the next digit in our result. 
Result so far: 51055.4839124
Subtract 3108 from 3760 to get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Let's proceed to step 16:
If we divide 6520 by 777, we get 8 and a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 51055.48391248
Deduct 6216 from 6520 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

After the division, we end up with 51055.48391248 and a remainder of 3.04e-07.
