Let's divide 939880 by 77
We want to divide 939880 by 77.

Let's proceed to step 1:
The number 77 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 77

Moving on to step 2:
93 divided by 77 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 93 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 77

Step 3:
77 can be fit into 169 2 times, resulting in a remainder of 15.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 15 after subtracting 154 from 169.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 77

Step 4:
When dividing 158 by 77, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 154 from 158 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 77

Moving on to step 5:
48 divided by 77 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 1220.0
If we take 0 away from 48, we end up with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 77

On to step 6:
If we divide 480 by 77, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 12206.0
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 77 is 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 12206.2
If we subtract 154 from 180, we get 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 8:
When dividing 260 by 77, we get 3 with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 12206.23
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.

Advancing to step 9:
The number 77 fits into 290 3 times, leaving a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 12206.233
Subtracting 231 from 290 leaves us 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.

The final result is 12206.233 with a remainder of 0.0059.
