We look at the division of 77599847 by 77 
We want to figure out the number of times 77599847 can be divided by 77.

Going ahead to step 1:
7 divided by 77 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 77

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
The remainder is 0 after subtracting 77 from 77.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 77

Moving on to step 3:
When dividing 5 by 77, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 77

Advancing to step 4:
77 goes into 59 0 times with a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 59, we get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 77

Let's proceed to step 5:
When dividing 599 by 77, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 1007.0
If we take 539 away from 599, we end up with 60.
Fetch the next digit (8) from the dividend, attach it to 60 and continue: 608 / 77

Step 6:
608 divided by 77 is 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 10077.0
If we take 539 away from 608, we end up with 69.
Take the next digit (4) from the dividend and append it to 69, then repeat: 694 / 77

On to step 7:
77 can be fit into 694 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 100779.0
If we take 693 away from 694, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 77

Let's proceed to step 8:
17 divided by 77 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 1007790.0
Subtract 0 from 17 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
When dividing 170 by 77, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1007790.2
Deduct 154 from 170 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
77 can be fit into 160 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1007790.22
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 1007790.22, and the remainder is 0.006.
