64454 divided by 77 
We want to figure out the number of times 64454 can be divided by 77.

On to step 1:
6 divided by 77 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 77

Advancing to step 2:
77 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 77

Going ahead to step 3:
The number 77 fits into 644 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 616 away from 644, we end up with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 77

On to step 4:
285 divided by 77 is 3 with a remainder of 54.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 231 from 285 leaves us with 54.
Grab the next digit (4) from the dividend, add it to 54, then carry on: 544 / 77

Let's proceed to step 5:
When dividing 544 by 77, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 837.0
If we subtract 539 from 544, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
77 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 837.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
500 divided by 77 is 6 with a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 837.06
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
If we divide 380 by 77, we get 4 and a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 837.064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
720 divided by 77 is 9 with a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 837.0649
If we take 693 away from 720, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 10:
If we divide 270 by 77, we get 3 and a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 837.06493
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 11:
77 can be fit into 390 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 837.064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
50 divided by 77 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 837.064935
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
When dividing 500 by 77, we get 6 with a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 837.06493506
If we subtract 462 from 500, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 837.06493506, and the remainder is 3.8e-08.
