Let's divide 407939 by 77
Our goal is to divide 407939 by 77.

Moving on to step 1:
The number 77 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 77

Step 2:
77 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 77

Going ahead to step 3:
77 goes into 407 5 times with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 385 from 407 leaves us with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 77

Going ahead to step 4:
The number 77 fits into 229 2 times, leaving a remainder of 75.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Deduct 154 from 229 and we're left with 75.
Take the next digit (3) from the dividend and append it to 75, then repeat: 753 / 77

Going ahead to step 5:
When dividing 753 by 77, we get 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
Deduct 693 from 753 and we're left with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 77

Moving on to step 6:
If we divide 609 by 77, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 5297.0
If we take 539 away from 609, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
If we divide 700 by 77, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 5297.9
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 77 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 5297.9
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
700 divided by 77 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 5297.909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
77 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 5297.909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
When dividing 700 by 77, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 5297.90909
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
When dividing 70 by 77, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 5297.90909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
700 divided by 77 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 5297.9090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 77, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 5297.9090909
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 5297.9090909 with a remaining 7e-08.
