Let's divide 753790 by 77
We're looking to find how many times 77 goes into 753790.

On to step 1:
The number 77 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 77

Moving on to step 2:
If we divide 75 by 77, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 77

Let's proceed to step 3:
77 can be fit into 753 9 times, resulting in a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 753, we end up with 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 77

Moving on to step 4:
The number 77 fits into 607 7 times, leaving a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 539 from 607 and we're left with 68.
Bring next digit (9) of the dividend behind the 68 and repeat the process: 689 / 77

Step 5:
77 goes into 689 8 times with a remainder of 73.
Write down 8 as next digit of the result. 
Result so far: 978.0
Subtract 616 from 689 to get 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 77

Let's proceed to step 6:
77 goes into 730 9 times with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 9789.0
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 9789.4
If we subtract 308 from 370, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
The number 77 fits into 620 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9789.48
If we take 616 away from 620, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 77 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9789.48
If we take 0 away from 40, we end up 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.

Advancing to step 10:
The number 77 fits into 400 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 9789.4805
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
150 divided by 77 is 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 9789.48051
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 12:
When dividing 730 by 77, we get 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 9789.480519
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
370 divided by 77 is 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 9789.4805194
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 77, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 9789.48051948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 9789.48051948, with a leftover of 4e-09.
