We look at the division of 770502 by 77 
We're looking to find how many times 77 goes into 770502.

Let's proceed to step 1:
7 divided by 77 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 77

On to step 2:
If we divide 77 by 77, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 77 from 77 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 77

Going ahead to step 3:
77 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 77

Advancing to step 4:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 77

On to step 5:
If we divide 50 by 77, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1000.0
Subtract 0 from 50 to get 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 77

Advancing to step 6:
When dividing 502 by 77, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 10006.0
Deduct 462 from 502 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.

Moving on to step 7:
77 goes into 400 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 10006.5
Subtracting 385 from 400 leaves us 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.

Moving on to step 8:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 10006.51
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.

Advancing to step 9:
77 can be fit into 730 9 times, resulting in a remainder of 37.
The next digit of our result is 9. 
Result so far: 10006.519
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.

Advancing to step 10:
When dividing 370 by 77, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 10006.5194
Subtract 308 from 370 to 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.

On to step 11:
When dividing 620 by 77, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10006.51948
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.

Let's proceed to step 12:
When dividing 40 by 77, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10006.51948
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.

Step 13:
If we divide 400 by 77, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 10006.5194805
Deduct 385 from 400 and we're left 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.

Step 14:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 10006.51948051
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 10006.51948051, with a leftover of 7.3e-08.
