We look at the division of 76973977 by 64 
Let's see how many times 64 fits into 76973977.

Step 1:
64 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 64

Going ahead to step 2:
When dividing 76 by 64, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 64 away from 76, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 64

On to step 3:
64 can be fit into 129 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 1 after subtracting 128 from 129.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 64

On to step 4:
17 divided by 64 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 120.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 64

Step 5:
The number 64 fits into 173 2 times, leaving a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 1202.0
If we take 128 away from 173, we end up with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 64

Going ahead to step 6:
459 divided by 64 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 12027.0
The remainder is 11 after subtracting 448 from 459.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 64

Going ahead to step 7:
When dividing 117 by 64, we get 1 with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 120271.0
Deduct 64 from 117 and we're left with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 64

Step 8:
64 goes into 537 8 times with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 1202718.0
If we subtract 512 from 537, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 64 is 3 with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 1202718.3
Deduct 192 from 250 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
When dividing 580 by 64, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 1202718.39
If we subtract 576 from 580, we 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.

On to step 11:
The number 64 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1202718.39
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 64 fits into 400 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 1202718.3906
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 1202718.39062
Subtract 128 from 160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
If we divide 320 by 64, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1202718.390625
If we take 320 away from 320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
64 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1202718.390625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1202718.390625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1202718.390625 and a remainder of 0.0.
