642031 ÷ 77 
Our goal is to divide 642031 by 77.

Moving on to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 77

On to step 2:
64 divided by 77 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 77

On to step 3:
If we divide 642 by 77, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 26 after subtracting 616 from 642.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 77

Let's proceed to step 4:
77 can be fit into 260 3 times, resulting in a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we take 231 away from 260, we end up with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 77

On to step 5:
77 can be fit into 293 3 times, resulting in a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 833.0
If we subtract 231 from 293, we get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 77

Advancing to step 6:
If we divide 621 by 77, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 8338.0
Subtract 616 from 621 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 77, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 8338.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
77 can be fit into 500 6 times, resulting in a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 8338.06
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
77 goes into 380 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 8338.064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
If we divide 720 by 77, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 8338.0649
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
270 divided by 77 is 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 8338.06493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 12:
77 can be fit into 390 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8338.064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
The number 77 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8338.064935
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
77 goes into 500 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 8338.06493506
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 8338.06493506 with a remainder of 3.8e-08.
