We're dividing 783600 by 77 
We want to figure out the number of times 783600 can be divided by 77.

Advancing to step 1:
When dividing 7 by 77, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 77

Step 2:
When dividing 78 by 77, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 77 from 78 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 77

Let's proceed to step 3:
When dividing 13 by 77, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 77

Advancing to step 4:
The number 77 fits into 136 1 times, leaving a remainder of 59.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 77 from 136 and we're left with 59.
Fetch the next digit (0) from the dividend, attach it to 59 and continue: 590 / 77

Let's proceed to step 5:
77 goes into 590 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 1017.0
Subtracting 539 from 590 leaves us with 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 77

On to step 6:
510 divided by 77 is 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 10176.0
The remainder is 48 after subtracting 462 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 77 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 10176.6
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
77 can be fit into 180 2 times, resulting in a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 10176.62
Subtracting 154 from 180 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
77 goes into 260 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 10176.623
If we take 231 away from 260, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
77 goes into 290 3 times with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 10176.6233
If we take 231 away from 290, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 10176.6233 with a remaining 0.00059.
