We look at the division of 7782743 by 770 
Our goal is to divide 7782743 by 770.

Let's proceed to step 1:
If we divide 7 by 770, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 770

Going ahead to step 2:
If we divide 77 by 770, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 770

Going ahead to step 3:
778 divided by 770 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 770 from 778, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 770

Step 4:
770 goes into 82 0 times with a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 82 to get 82.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 770

Going ahead to step 5:
770 goes into 827 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtracting 770 from 827 leaves us with 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 770

Advancing to step 6:
574 divided by 770 is 0 with a remainder of 574.
Use 0 as the next digit of our solution. 
Result so far: 1010.0
The remainder is 574 after subtracting 0 from 574.
Bring next digit (3) of the dividend behind the 574 and repeat the process: 5743 / 770

Advancing to step 7:
When dividing 5743 by 770, we get 7 with a remainder of 353.
Record the quotient 7 as the next digit in the result. 
Result so far: 10107.0
Subtracting 5390 from 5743 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 8:
770 goes into 3530 4 times with a remainder of 450.
The next digit of our result is 4. 
Result so far: 10107.4
Deduct 3080 from 3530 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 9:
770 can be fit into 4500 5 times, resulting in a remainder of 650.
Write down 5 as next digit of the result. 
Result so far: 10107.45
Subtract 3850 from 4500 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 10:
When dividing 6500 by 770, we get 8 with a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 10107.458
Deduct 6160 from 6500 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
If we divide 3400 by 770, we get 4 and a remainder of 320.
The next digit of our result is 4. 
Result so far: 10107.4584
Subtract 3080 from 3400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
770 goes into 3200 4 times with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 10107.45844
If we subtract 3080 from 3200, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 10107.45844 with a balance of 0.00012.
