Let's divide 39783434 by 77
We want to figure out the number of times 39783434 can be divided by 77.

Let's proceed to step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 77

Advancing to step 2:
The number 77 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 77

Advancing to step 3:
77 can be fit into 397 5 times, resulting in a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 385 from 397 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 77

Advancing to step 4:
The number 77 fits into 128 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 77 from 128 leaves us with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 77

Step 5:
77 goes into 513 6 times with a remainder of 51.
The next digit of our result is 6. 
Result so far: 516.0
Subtract 462 from 513 to get 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 77

Step 6:
When dividing 514 by 77, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 5166.0
The remainder is 52 after subtracting 462 from 514.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 77

On to step 7:
If we divide 523 by 77, we get 6 and a remainder of 61.
The next digit of our result is 6. 
Result so far: 51666.0
The remainder is 61 after subtracting 462 from 523.
Fetch the next digit (4) from the dividend, attach it to 61 and continue: 614 / 77

On to step 8:
If we divide 614 by 77, we get 7 and a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 516667.0
Deduct 539 from 614 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 9:
The number 77 fits into 750 9 times, leaving a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 516667.9
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 10:
77 can be fit into 570 7 times, resulting in a remainder of 31.
The next digit of our result is 7. 
Result so far: 516667.97
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
77 goes into 310 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 516667.974
If we take 308 away from 310, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
The number 77 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 516667.974
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 77, we get 2 and a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 516667.97402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
The number 77 fits into 460 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 516667.974025
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 15:
77 can be fit into 750 9 times, resulting in a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 516667.9740259
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 16:
The number 77 fits into 570 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 516667.97402597
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 516667.97402597 with a remaining 3.1e-08.
