We look at the division of 957309 by 77 
We want to divide 957309 by 77.

Advancing to step 1:
77 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 77

Let's proceed to step 2:
77 goes into 95 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 77 from 95 leaves us with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 77

Let's proceed to step 3:
If we divide 187 by 77, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 154 from 187, we get 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 77

Going ahead to step 4:
77 goes into 333 4 times with a remainder of 25.
Write down 4 as next digit of the result. 
Result so far: 124.0
Deduct 308 from 333 and we're left with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 77

On to step 5:
77 goes into 250 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 1243.0
The remainder is 19 after subtracting 231 from 250.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 77

Advancing to step 6:
199 divided by 77 is 2 with a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 12432.0
Deduct 154 from 199 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
The number 77 fits into 450 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 12432.5
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
650 divided by 77 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 12432.58
Subtract 616 from 650 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
77 can be fit into 340 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 12432.584
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 12432.5844
Subtract 308 from 320 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 12432.5844, with a leftover of 0.00012.
