When dividing 6 by 977, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 977

Advancing to step 2:
62 divided by 977 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 62 to get 62.

Let's proceed to step 5:
The number 977 fits into 3915 4 times, leaving a remainder of 7.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 3908 from 3915 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 977

The remainder is 759 after subtracting 0 from 759.
Fetch the next digit (8) from the dividend, attach it to 759 and continue: 7598 / 977

Going ahead to step 8:
When dividing 7598 by 977, we get 7 with a remainder of 759.
Put 7 as the next digit of the answer. 
Result so far: 64007.0
Deduct 6839 from 7598 and we're left with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Let's proceed to step 9:
When dividing 7590 by 977, we get 7 with a remainder of 751.
The next digit of our result is 7. 
Result so far: 64007.7
Subtract 6839 from 7590 to get 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Moving on to step 10:
977 can be fit into 7510 7 times, resulting in a remainder of 671.
Write down 7 as next digit of the result. 
Result so far: 64007.77
The remainder is 671 after subtracting 6839 from 7510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

The final outcome is 64007.77, with a leftover of 0.671.
