391471 ÷ 77 
Let's see how many times 77 fits into 391471.

Let's proceed to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 77

Advancing to step 2:
77 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 77

Advancing to step 3:
391 divided by 77 is 5 with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 385 from 391, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 77

On to step 4:
77 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 77

Moving on to step 5:
647 divided by 77 is 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
Subtracting 616 from 647 leaves us with 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 77

Let's proceed to step 6:
77 goes into 311 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 5084.0
If we subtract 308 from 311, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 77, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5084.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 5084.03
Deduct 231 from 300 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
690 divided by 77 is 8 with a remainder of 74.
The next digit of our result is 8. 
Result so far: 5084.038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
The number 77 fits into 740 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 5084.0389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
470 divided by 77 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 5084.03896
The remainder is 8 after subtracting 462 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 77, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 5084.038961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
When dividing 30 by 77, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5084.038961
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 5084.03896103
Subtracting 231 from 300 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 5084.03896103 and a remainder of 6.9e-08.
