51683653 ÷ 77 
We're looking to find how many times 77 goes into 51683653.

Moving on to step 1:
77 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 77

Step 2:
77 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 77

Let's proceed to step 3:
77 goes into 516 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 54 after subtracting 462 from 516.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 77

Moving on to step 4:
548 divided by 77 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtracting 539 from 548 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 77

Advancing to step 5:
If we divide 93 by 77, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 671.0
If we take 77 away from 93, we end up with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 77

On to step 6:
77 can be fit into 166 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 6712.0
Subtracting 154 from 166 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 77

Moving on to step 7:
The number 77 fits into 125 1 times, leaving a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 67121.0
Deduct 77 from 125 and we're left with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 77

On to step 8:
77 goes into 483 6 times with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 671216.0
Deduct 462 from 483 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
The number 77 fits into 210 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 671216.2
The remainder is 56 after subtracting 154 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 77, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 671216.27
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
210 divided by 77 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 671216.272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
77 goes into 560 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 671216.2727
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
210 divided by 77 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 671216.27272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
77 goes into 560 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 671216.272727
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 15:
210 divided by 77 is 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 671216.2727272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
77 can be fit into 560 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 671216.27272727
Deduct 539 from 560 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 671216.27272727, and the remainder is 2.1e-08.
