We look at the division of 64691708 by 977 
We want to divide 64691708 by 977.

Advancing to step 1:
If we divide 6 by 977, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 977

Advancing to step 2:
64 divided by 977 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 977

Advancing to step 3:
977 can be fit into 646 0 times, resulting in a remainder of 646.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 646, we get 646.
Grab the next digit (9) from the dividend, add it to 646, then carry on: 6469 / 977

On to step 4:
6469 divided by 977 is 6 with a remainder of 607.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5862 away from 6469, we end up with 607.
Take the next digit (1) from the dividend and append it to 607, then repeat: 6071 / 977

Let's proceed to step 5:
977 goes into 6071 6 times with a remainder of 209.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 5862 from 6071 and we're left with 209.
Include the next digit (7) from the dividend after 209, then repeat: 2097 / 977

On to step 6:
2097 divided by 977 is 2 with a remainder of 143.
The next digit of our result is 2. 
Result so far: 662.0
The remainder is 143 after subtracting 1954 from 2097.
Grab the next digit (0) from the dividend, add it to 143, then carry on: 1430 / 977

Advancing to step 7:
When dividing 1430 by 977, we get 1 with a remainder of 453.
Write down 1 as next digit of the result. 
Result so far: 6621.0
If we subtract 977 from 1430, we get 453.
Take the next digit (8) from the dividend and append it to 453, then repeat: 4538 / 977

Moving on to step 8:
977 can be fit into 4538 4 times, resulting in a remainder of 630.
The number 4 becomes the next digit in our result. 
Result so far: 66214.0
The remainder is 630 after subtracting 3908 from 4538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 9:
977 can be fit into 6300 6 times, resulting in a remainder of 438.
The next digit of our result is 6. 
Result so far: 66214.6
Subtracting 5862 from 6300 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 10:
977 can be fit into 4380 4 times, resulting in a remainder of 472.
Put 4 as the next digit of the answer. 
Result so far: 66214.64
Deduct 3908 from 4380 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 11:
977 can be fit into 4720 4 times, resulting in a remainder of 812.
Put 4 as the next digit of the answer. 
Result so far: 66214.644
If we take 3908 away from 4720, we end up with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

The final outcome is 66214.644, with a leftover of 0.0812.
