We're dividing 783820 by 77 
Let's see how many times 77 fits into 783820.

Advancing to step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 77

Going ahead to step 2:
The number 77 fits into 78 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 78 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 77

Step 3:
When dividing 13 by 77, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 77

Let's proceed to step 4:
77 goes into 138 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 77 from 138 leaves us with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 77

On to step 5:
612 divided by 77 is 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 1017.0
If we take 539 away from 612, we end up with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 77

Advancing to step 6:
730 divided by 77 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 10179.0
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.

Step 7:
370 divided by 77 is 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 10179.4
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.

Advancing to step 8:
77 goes into 620 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10179.48
Deduct 616 from 620 and we're left 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.

Advancing to step 9:
77 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10179.48
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.

Moving on to step 10:
The number 77 fits into 400 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10179.4805
The remainder is 15 after subtracting 385 from 400.
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 11:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 10179.48051
Subtract 77 from 150 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 12:
If we divide 730 by 77, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 10179.480519
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.

Advancing to step 13:
77 goes into 370 4 times with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 10179.4805194
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.

Let's proceed to step 14:
77 can be fit into 620 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 10179.48051948
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.

In conclusion, the division gives 10179.48051948 with a balance of 4e-09.
