We're dividing 648839 by 77 
We want to figure out the number of times 648839 can be divided by 77.

On to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 77

Going ahead to step 2:
The number 77 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 77

Step 3:
77 goes into 648 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 32 after subtracting 616 from 648.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 77

Going ahead to step 4:
When dividing 328 by 77, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 308 from 328 leaves us with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 77

Advancing to step 5:
If we divide 203 by 77, we get 2 and a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 842.0
Subtracting 154 from 203 leaves us with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 77

Step 6:
When dividing 499 by 77, we get 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 8426.0
Subtracting 462 from 499 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
77 goes into 370 4 times with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 8426.4
The remainder is 62 after subtracting 308 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
The number 77 fits into 620 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8426.48
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 77 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8426.48
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
77 can be fit into 400 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8426.4805
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 8426.48051
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
77 can be fit into 730 9 times, resulting in a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 8426.480519
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
When dividing 370 by 77, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 8426.4805194
Deduct 308 from 370 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 77, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8426.48051948
If we take 616 away from 620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 8426.48051948, with a leftover of 4e-09.
