Let's divide 645192 by 77
We want to figure out the number of times 645192 can be divided by 77.

Advancing to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 77

Advancing to step 2:
64 divided by 77 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 77

Going ahead to step 3:
The number 77 fits into 645 8 times, leaving a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 616 from 645 leaves us with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 77

Step 4:
When dividing 291 by 77, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 231 from 291, we get 60.
Grab the next digit (9) from the dividend, add it to 60, then carry on: 609 / 77

Going ahead to step 5:
The number 77 fits into 609 7 times, leaving a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 837.0
If we subtract 539 from 609, we get 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 77

Advancing to step 6:
77 can be fit into 702 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 8379.0
Subtracting 693 from 702 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
77 can be fit into 90 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 8379.1
If we take 77 away from 90, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
77 goes into 130 1 times with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 8379.11
Subtract 77 from 130 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 8379.11 and a remainder of 0.053.
