66373937 ÷ 783 
We want to divide 66373937 by 783.

Step 1:
783 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 783

Going ahead to step 2:
783 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 783

On to step 3:
783 goes into 663 0 times with a remainder of 663.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 663, we end up with 663.
Append the next digit (7) from the dividend to 663 and continue with: 6637 / 783

Going ahead to step 4:
The number 783 fits into 6637 8 times, leaving a remainder of 373.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6264 from 6637 to get 373.
Grab the next digit (3) from the dividend, add it to 373, then carry on: 3733 / 783

Going ahead to step 5:
3733 divided by 783 is 4 with a remainder of 601.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 3132 from 3733 and we're left with 601.
Fetch the next digit (9) from the dividend, attach it to 601 and continue: 6019 / 783

On to step 6:
783 can be fit into 6019 7 times, resulting in a remainder of 538.
Write down 7 as next digit of the result. 
Result so far: 847.0
If we subtract 5481 from 6019, we get 538.
Bring next digit (3) of the dividend behind the 538 and repeat the process: 5383 / 783

Step 7:
783 goes into 5383 6 times with a remainder of 685.
The number 6 becomes the next digit in our result. 
Result so far: 8476.0
Deduct 4698 from 5383 and we're left with 685.
Bring next digit (7) of the dividend behind the 685 and repeat the process: 6857 / 783

Moving on to step 8:
6857 divided by 783 is 8 with a remainder of 593.
The next digit of our result is 8. 
Result so far: 84768.0
Subtracting 6264 from 6857 leaves us with 593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Advancing to step 9:
5930 divided by 783 is 7 with a remainder of 449.
The next digit of our result is 7. 
Result so far: 84768.7
Subtracting 5481 from 5930 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 10:
The number 783 fits into 4490 5 times, leaving a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 84768.75
The remainder is 575 after subtracting 3915 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 11:
When dividing 5750 by 783, we get 7 with a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 84768.757
If we take 5481 away from 5750, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Step 12:
If we divide 2690 by 783, we get 3 and a remainder of 341.
The next digit of our result is 3. 
Result so far: 84768.7573
The remainder is 341 after subtracting 2349 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 13:
The number 783 fits into 3410 4 times, leaving a remainder of 278.
The number 4 becomes the next digit in our result. 
Result so far: 84768.75734
Subtract 3132 from 3410 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.

Let's proceed to step 14:
The number 783 fits into 2780 3 times, leaving a remainder of 431.
Use 3 as the next digit of our solution. 
Result so far: 84768.757343
Subtracting 2349 from 2780 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 15:
783 can be fit into 4310 5 times, resulting in a remainder of 395.
The next digit of our result is 5. 
Result so far: 84768.7573435
Deduct 3915 from 4310 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Step 16:
783 can be fit into 3950 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 84768.75734355
The remainder is 35 after subtracting 3915 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 84768.75734355, and the remainder is 3.5e-08.
